(This product may have small flaws, in some cases they may be negligible).
Despite the fact that the origin of Parcheesi and its date of invention are still unclear, there are indications that bring us closer to the Mayan world of the 7th century with patolli, a game very similar to current Parcheesi. Although, the current word, Parcheesi, comes from the Hindustani pacisi o pacis, which means 25. This was the maximum figure that could be scored when throwing the shells of a mollusk that the Indians used instead of the current dice. In turn, pacisi (which is pronounced more or less parchisii) is the abbreviation of a game called chaupar, of great tradition in India.
However, for the most familiar form of the famous game we have to look back to the second half of the 16th century, to a game that Francisco I de 'Medici gave to Felipe II. Some compare the meaning of the game and its appearance with that of medieval labyrinths that symbolically recreated the path of life and pilgrimage routes. In fact, it is difficult to know how the game got to the West. It is very possible that the Muslims introduced it, that in the 7th century the chess of the Sassanid Empire was already adopted, and that it arrived in Western Europe in the 9th century with the Islamic invasion of the Iberian Peninsula.
The tradition and history of this game also passes through us and lives on through each player who approaches the board and walks through its squares. Therefore, we invite everyone, whether experienced players or new discoverers, to take part in this living piece of history.

Russian security officer dies in Moscow shooting incident
An unidentified gunman opened fire behind the FSB's headquarters in central Moscow, wounding five others.

By Associated Press Reporter
An unidentified gunman opened fire outside the Moscow headquarters of Russia's top security agency, killing one officer and wounding five others, officials have said.
https://www.belfasttelegraph.co.uk/news/world-news/russian-security-officer-dies-in-moscow-shooting-incident-38800182.html
https://www.belfasttelegraph.co.uk/news/world-news/dd257/38800180.ece/AUTOCROP/h342/bpanews_e3552296-d043-466f-8e91-79e4483fcd04_1
The Federal Security Service, or FSB, said the assailant was acting alone and did not enter its building.
Earlier, it said the assailant had been "neutralised" — a term usually used by Russian officials when an assailant is killed.
The Health Ministry said that five other people were wounded in the shooting, including two security officers who were badly injured by the gunman.
The FSB said the shooting occurred at a building directly behind its headquarters on Lubyanka Square.

The agency, which is the main successor agency to the Soviet-era KGB, would not give further details or comment on the attacker's motives.
In a video shared on social media, loud shots and bangs can be heard.
Robert Anchipolovsky, an Israeli musician, was on the way to his concert in Moscow when he started filming the street from his car. As he started filming, the shooting began.
"I thought it was fireworks and then I saw how police started to fall on the tarmac and crouch down," Mr Anchipolovsky told The Associated Press.
Vladimir Putin's spokesman, Dmitry Peskov, said the president had been informed of the shooting that came shortly after the Russian leader's annual news conference.
At about the same time when the shooting happened, Mr Putin made a speech at a Kremlin concert for FSB and other Russian security personnel.
In a speech marking the date the Soviet secret police was founded, Mr Putin hailed its officers for their efforts in combating terrorism and organised crime.

Maronite Patriarch Cardinal Mar Bechara Boutros al-Rai slammed on Sunday the bickering rival Lebanese politicians , held them responsible for the numerous explosions and security incidents plaguing the country and prayed to God to enlighten their minds.
"Political parties which refuse to reconcile with each other and understand one another , and those who are obstructing the formation of a new government and threatening or planning for presidential vacuum are responsible for all these crimes," Rai said during his Sunday Mass at the seat of the Maronite Patriarchate in Bkirki.
The purpose of the government should be to take of the human beings and not portfolios, he said in a veiled reference to Free Patriotic Movement leader Michel Aoun who has been dubbed as the last person standing behind the failure to form the cabinet.
Aoun has rejected a deal reached between rival parties on the rotation of portfolios in a 24-member cabinet based on the 8-8-8 formula.
"Let's pray that the Lord enlightens the minds of our officials so that we could overcome the crises," Rai said.
It said it was to punish Hezbollah for fighting alongside forces of Syrian President Bashar Assad.
Rai said it is the duty of the patriarchate to issue a national charter on the occasion of St. Maroun.
The document, which is expected to be issued following the monthly meeting of the council of Maronite bishops on Wednesday, holds onto the national principles and sets the priorities for a better future, the patriarch said.
The charter is based on three factors – national principles, concerns and priorities – Rai said earlier this week.
That is what the Lebanese folks been doing since the creation of Liban!
Need a lot of 'Enlightening', Rai … ask for some for the Religious Fatheads too.
The maronites patriarch prays for peace, understanding, tolerance, and respect amongst the different people's and politicians, on the other end of the scale there are religious leaders inciting revenge, killing, threats, fatwas for jihad licencing and approvals. Ummmmmmm, if the scale is weighing up good vs evil, then it's not hard to see the picture here.
He's also blessed with a brain..the only intelligent brain..in Lebanon mess.
You don't pray for peace, understanding and tolerance and go call a guy like bashar "reformist".
So far this patriarch has done nothing worth mentioning. He talks, talks but he didn't come up with anything, not for the Christians, not for the Lebanese.
Maybe you should do it..


Arsenal forward Theo Walcott believes it is only a matter of time before he returns to his best form after returning from injury that has kept him out since September.
The English international returned to Premier League action on Saturday when he was introduced for the final 20 minutes in the Gunners 2-0 win over former club Southampton.
The 24 year old admits that he has been somewhat rusty on his comeback, but feels it will not be long before he is up to full speed once again.
It is a challenge I can face, I have faced some in my short career so far.
It is nothing new to me, I know how to deal with it all. I have some fantastic people around me and know how good I am.
It will take a couple of games, but I am sure I will be back to my best very soon.
It has been longer than I thought, but it is so good to be back out on the pitch with the guys and playing in such a fantastic team.
Seeing the way we play football has been fairly pleasant to watch, but any player who is injured wants to go out there and perform.
It is frustrating at times, but you have just got to think about getting back fit as soon as you can, and I am happy to be back now.
Walcott was brought on as a substitute on the 70 minute mark but he didn't see much of the ball after coming on as most of the play was from the Gunners left-hand side. He had a wonderful chance to put Giroud through but rushed his pass. He was a bit rusty which is to be expected after a 2 month layoff and it was a relief to have him back on the pitch.
Walcott's return will come as a boost for Wenger because as good as Giroud has been, the over reliance on the French striker was taking its toll on him. His return will give the manager a chance to rest Giroud if necessary by playing the Englishman up front and although he didn't always convince when fielded as a central striker last season, his intelligent movement and smart finishing suggest he may be worth another try in the role.
Giroud will also benefit from Walcott's wing play as he provides the kind of exemplary service on which the Frenchman thrives. So, with fixtures coming thick and fast in the next 2 months it will be a pleasure for Wenger to have him back.
Can Walcott reprise his form from last season? Share your thoughts in the comments below.


Professor Steven Rothberg, the PVC (Research) at Loughborough University, officially declared the workshop open at 09:30, flanked by Professor Victor Murinde, the Director of CGF. More than 70 researchers, policy makers and practitioners from the UK, Netherlands, France, Canada, Cote d'Ivoire, Bulgaria, Israel, Iran, China, Kenya, Ghana, Nigeria, and Turkey came together to exchange ideas on preliminary research findings from the ongoing research project on 'Delivering Inclusive Financial Development and Growth', which is funded by the DFID and ESRC (Research Grant Ref. ES/N013344/2).
Importantly, the workshop was specially dedicated to a member of the research team of the project – Professor Christopher J. Green (Loughborough University), to celebrate his life-long contributions to economics and finance and to pay tribute to his exceptional mentorship of researchers both through his university academic career as well as his active involvement in the critical capacity building dimensions of the African Economic Research Consortium (AERC).
The keynote speech was given by Prof Njuguna Ndung'u, Executive Director of the AERC and former Governor of the Central Bank of Kenya. He eulogised Prof Green's dedication and contribution to the frontiers of research in economics and finance and to his exceptional contributions to the AERC Network.
'We should continue the legacy of Prof Christopher Green as we seek to provide answers to these and other questions relating to financial sector development and financial inclusion in developing countries, in general, and Africa, in particular.' said Prof Ndung'u.
Prof Ndung'u also shared his insights into 'Gaps, Challenges, and Policy Opinions in Financial Development and Financial Inclusion in Africa' and suggested three key elements that are fundamental to sustaining the digital evolution for financial development in Africa - 'Connectivity, interoperability, and electronic ID systems'.

Police Chief OD's on Stolen Fentanyl
by June Barrett · February 21, 2019
James Hughes Jr., 35, of Kirkersville, Ohio, died from a fentanyl overdose less than three months after he was appointed as chief of police. Unsettling evidence has surfaced indicating that Hughes stole the Fentanyl on which he overdosed from the police department's evidence room.
Lt. Ron Wright, from the nearby Reynoldsburg Police Department, said the drugs likely were evidence in other, on-going cases. "I'm no evidence room expert," said Wright, "but there are proper procedures," implying that such procedures may not have been followed, or that there was a lack of oversight. "Probably someone from the state's AG office should look into it," he said.
Authorities found Hughes in his home on May 25th, unresponsive because of ingestion of Fentanyl. Just two and a half months earlier on March 13th, the village council had convened a special meeting to name Hughes as chief. The previous chief Jeff Finley had resigned without notice, due to "irreconcilable differences" with the town's mayor, Terry Ashcraft.
After Hughes' death, some incidents about his past came to light. Whether or not they had been known to council members was not revealed. One such incident included a disorderly conduct conviction at a drive-thru restaurant in 2013. Department spokespersons have not said whether or not there is evidence of any drug use from Hughes' past, nor was his family available for comment.
"This just shows that no one is immune to this epidemic," said Wright.
Fentanyl is known to be more highly addictive than heroin. According to a Drug Enforcement Administration (DEA), administrative brief, Fentanyl "Remains the Most significant Synthetic Opioid Threat and Poses the Greatest Threat to the Opioid User Market in the United States.
As this story sadly shows, no one is immune from the effects of the opioid crisis gripping America. A young police chief steals from his own department for a drug which kills him, leaving his grieving family alone and suffering.

I think one of the worse fears that human beings have, and it is a primal thing, is to be eaten alive. It is really why we have this "fight or flight," reaction that is programmed into our DNA. The chances of the average human being today being eaten alive is almost zero but we still have our fight or flight protection built into who we are.
Now there is a spiritual equivalent to being eaten alive. It is very possible that we have someone in our lives who have the capacity to tear at our souls and eat us alive from the inside out. This is a great danger and takes the wisdom and strength of God Himself through the power of the Holy Spirit to deal with. If you are dealing with that today. If there is someone in your life that is ripping away at your very soul and the essence of who you are then my prayer for you today is to take up the shield of faith.
This shield is more real than any human shield that has been used in warfare for centuries. This is a shield that exists in the Kingdom of God in which we walk. And if we use it, if we pick it up, it will protect us from the fiery darts of an enemy who, if allowed, will tear your heart to pieces. The enemy uses people as arrows and he never misses the unprotected.
These arrows are not just arrows, which would be deadly enough, they are fiery arrows intended not just to kill and destroy but to burn. This fire, brothers and sisters, is quenched by the living waters that flows from the throne room of God. Come to God today before His throne, put the fire out, take up the shield of faith and stand in the evil day. May God bless you and be with you in the battle.
Is there fruit hanging from your branches? Has the life of Christ in you welled up from the depths of your spirit and produced fruit that others can identify and partake of? You have heard the saying that the fruit identifies the root. If others were looking at you, would they know what kind of tree that you were by the fruit that they could see? There is one thing about the life of Christ, it is unmistakable. It radiates, it produces passion, people can even see it on your face. It wells up in us. As God pours in His living waters into the very depths ow who we are, as the life of Christ bubbles up in us, it has to have an expression.
Artists must paint, singers must sing, musicians must play, sculptors must sculpt and writers must write. It is so vital to who they are, they are just out of sorts if they are not able to have an outlet for the passions that they were born with. It is not even something that they have any control over. If the life of Christ was born into the very depths of who we are it must and will have an expression. The creator of all things, dwelling in you, will love others, will comfort others, will share the truth with others. To those who have Christ living in them, to talk about the one they love is to turn their light on. Only as they are giving expression to that life that is in them are they truly alive.
I give thanks this morning for the Body of Christ, the saints around the world, His remnant people. There is one thing that I have noticed as I have met genuine saints from every conceivable background. They have " eyes of understanding." Not head knowledge, but eyes of understanding. Notice what Paul is praying for here; that they may have a deeper wisdom, a deeper revelation, an understanding that is more enlightened. His focus for the saints is that they have an even greater revelation of the riches of our inheritance. Is that how we pray today brothers and sisters? Do we have our eyes of understanding so focused on the riches of His glory that our prayers for the saints is that their understanding of the riches of His glory simply increases? Very rarely if ever do we see the Apostles pray for an alleviation of circumstances, no we see that the prayers are for a greater revelation of the glory of God and the eternal world to come. It is in this revelation that we are empowered to stand in the midst of any circumstances.
Too often the prayers of the saints are focused on the alleviation of the immediate physical circumstances, not realizing that the true power of those who walk the Kingdom walk, who walk not according to the flesh but according to the Spirit, lies not in an alleviation of circumstances but an elevation of Spiritual awareness. And who gives us this elevation of Spiritual awareness? "The Father of Glory." The very essence of glory, glory itself. God the Father is not glorious, He is glory itself. Just a glimpse of His glory elevates us high above the circumstances of our lives. We see this when Peter steps out of the boat in the midst of a raging storm. As His eyes are focused upon God, He is elevated above the storm. That which was sent to destroy him, now simply becomes a vehicle to bring glory to God. Right now, in the midst of your circumstances, what would bring God the most glory? We already know that God can calm any raging storm at any time, yet He bids us come up higher for His glories sake. He prepares a table before us in the presence of our enemies. While they rage with all of their fury, we sit in peace in His presence and this confounds the enemy of our souls and brings glory to God, and in this, goodness and mercy follows us all the days of our lives.

Rachlin, Mena, BSO Bust the Chart
by David Patterson
February 1, 2019 February 1, 2019 by David Patterson
Mena, Rachlin, and BSO pitched a peculiarly bonded appointment with Haydn, Mendelssohn, and Janáček. The 43-year old Lithuanian-born Julian Rachlin, standing at 83rd among "The World's Greatest Violinists," should certainly rise in ranking after his appearance Thursday evening at Symphony Hall. Boston's audience loved him. From Juanjo Mena on the podium stemmed an organic approach that would lead to sound-structure substance.
Haydn's Symphony No. 44, his Trauersinfonie, or Mourning Symphony, became more or less a quest for the single statement under guest conductor Juanjo Mena. Haydn's classical antecedent- consequent phrasing ascended from a simpler question and answer with Mena melding shorter phrases, the result being a large seamless outcome. Mena shaped a forceful four-note figure, a motto of sorts, in the first movement and played with dynamic contrasts. Yet Mena's all-in-one Allegro con brio grounded Haydn's nifty shifts. With Haydn come surprises. In this symphony, the usual third movement minuet came earlier. The trio could have been another surprise, but Mena played that down. Finely molded lines in strict canon took over. This was a very repetitious, near-boring iteration of the second movement.
In the Adagio, Mena often looked to the first violins, hands painting the melody that Haydn so adored. In the Finale: Presto, as with the rest of the symphony, the aesthetic of heightened emotionalism, or Sturm und Drang, gave way to more oneness.
Julian Rachlin hears in Mendelssohn a "charming person not an angry man" one full of inspiration, joy. Near the hand-held portion of the bow Rachlin would draw weightlessness opposite of the expected. Rather than exacting intonation, Rachlin would reach out for sunshine where shade often spreads. That is Rachlin's melodic Mendelssohn the Boston audience heard throughout the Violin Concerto in E Minor. Remarkably, the Allegro Molto Appassionato, rapid passage work popped with certain exuberance under Rachlin's deft fingers.

During moments of orchestral intervals, Rachlin reacted with a bit of body bobbing. These rare instances only heightened the benevolence pervading this Mendelssohn. And the cadenza, as with Rachlin's entire concerto musing, lit up with virtuosic restraint, still more humanity pouring out of his violin.
High harmonics on the E string somehow astonishingly allied with the lowest notes on the G string. Still more, his is not a big sound.
Warmth abounded in the Andante. For the finale, first in minor then in major, Rachlin had to be thinking of a "celebration of joy," his own words. Goodbye to brilliance and hello to feathery, whimsical, out-of-this world playing, ingenious in concept and execution.
Julian Rachlin steered Mena and the BSO clear of sentimentality to share higher aims. Embracing optimism and assurance clearly separates this violinist from today's crowded field of artists swept up with I can play it faster. Rachlin truly is filling a vacuum. He had Boston's audience standing and cheering. On a night where a polar vortex kept some from attending, those who were at Symphony Hall would, no surprise, would vote—with their cheers and shouts— this magnificent artist way up in the polling charts of all-time great violinists.
The BSO, too, touched deeply. An ultimate fineness, an extraordinary transparency akin to chamber playing wondrously complemented Rachlin.
Janáček's Suite from The Cunning Little Vixen turns one of his operas into orchestral storytelling without the picturebook qualities of the original. Why not follow BSO's presentation of Firebird Suite of Stravinsky with titles shown on the overhead screen? The voluptuous, the haunting, the memorable English Horn of Robert Sheena here and later in the following Janáček is a must-count among the best BSO moments
Next, awakened brass with tympani stirred up the opening fanfare of Janáček's Sinofonietta to spine-tingling effect. In "The Castle, Brno," the BSO threw a sudden royal low-roar scare, startlingly shifted to fearsome festivity, morphed to the pastoral, and warmed to the romantic. Later, BSO delivered waves of strings, brass fanfares and rocketing woodwinds. "Town Hall"—where Hitchcock thrillers perhaps got mileage out the composer's 1926 work —missed such suspense.
The audience applauded enthusiastically it appeared more for the impeccable and refined BSO than, perhaps, for Janáček's travelogue of the militaristic and festive.

Some thoughts from attending Thursday night:
1) Juanjo Mena is really underrated. I've now heard 3 or 4 concerts he's conducted with the BSO, and they have never been anything less than wonderful. I still remember his performance several years ago of Schubert's 9th, the best I've ever heard. I hope we hear a lot more of him in the years to come. There are few guest conductors of his generation that I enjoy more.
2) Neither we nor others in our row, all regular attendees, thought a whole lot of Julian Rachlin. His vibrato is so wide that it's challenging to listen to. He doesn't have a big sound a la Vadim Repin. I did not care for his grimaces, body jerks, and visual performance. That aspect of his playing felt cheap, distracting, and divorced from what I actually heard. Unlike David Patterson, I think his ranking on the list arguably should go down, not up. If the BSO does book him again, we'll probably trade out of that concert unless we really want to hear the rest of the program.
3) The BSO had a really good night on Thursday. The playing throughout was gorgeous, especially the Haydn and the violin concerto. I really enjoyed the Sinfonietta, although it's a piece I've only heard in recording a few times before. But this performance was very engaging.
Comment by Mogulmeister — February 1, 2019 at 6:10 pm
However does Mr. Patterson know what the audience was applauding at the conclusion of Jancek's Sinfonietta? I was applauding for both the BSO's virtuosic performance and the piece itself, which I had never heard in a live performance.
I'd prefer the reviewer just state his opinion rather than inferring the audience shares it.
Comment by Peter Johnson — February 2, 2019 at 10:06 am
I agree with Mr. Johnson. The Janáček pieces were for me the highlight of this concert, particularly the Sinfonietta which I had heard live only once before (but performed then by a ballet orchestra). But where were the BSO regular trumpeters? Also, it was good to see a couple of the BSO's Wagner tubas being put to good use.
Comment by Dennis Milford — February 2, 2019 at 4:43 pm
Dennis Milford, all four of the trumpet players on the regular BSO roster were playing the Sinfonietta. But the work requires 12 trumpets plus two bass trumpets—as many trumpeters as first violinists—and so there were naturally a lot of extra players.
Comment by Stephen Owades — February 2, 2019 at 10:44 pm
I can understand Mr. Milford: First trumpet Thomas Rolfs was not in sight on Friday. Several other regulars were.
Comment by martin cohn — February 3, 2019 at 9:05 am
Martin Cohn, Tom Rolfs was at the far audience-right end of the row of trumpets. I couldn't see him unless I leaned forward from my side-first-balcony seat, and I'm not surprised that you missed seeing him altogether.
Comment by Stephen Owades — February 3, 2019 at 1:57 pm
I don't review things very often, but this concert for me felt like a must, and I am expressing my views alone. The Haydn was for me good enough, the Mendelssohn with Mr. Rachlin was fleet and assured with the orchestra in fine form, but the Janacek was simply superb especially what for me is the finest performance I have heard of the Sinfonietta, which I'd wager will go down as one of the BSO's memorable performances among the many. People who missed this due to the Arctic cold I hope can make a try for the repeat concert on Tuesday or tune in on WGBH next Monday February 11th. Simply not to be missed whatever is possible for you. The Brass in the finale is still ringing bouncing across my study walls with even the Northern vortex pausing to tune in.
Comment by Peter LeSourd Barkley — February 3, 2019 at 9:20 pm
Thank you for placing the BSO trumpeters. I could not see them from 2nd balcony right.
Sorry, this comment forum is now closed.

my feet were cold and our path oddly shaped.
well attended and a notable beginning.

The Shenandoah Valley Quilters Guild celebrated its 25th anniversary in January 2012. Read on to find out how our group got its start . . .
Pages of the Past – 1986
Dorothy Burks Williams and her husband retired from Illinois to their farm in the Shenandoah Valley of Virginia. Her first activity was to find a quilt guild.
On Saturday, January 25, 1987, between two record-breaking snowstorms, nine enthusiastic women met and our Guild was born. Besides Dorothy, the charter members were Eleanor Canter, Guadalupe Cline, Sue Hodges, Barbara Johnson, Beryl Lawson, Paula Tehlewitz, Elsie Terry and Terry Wessel.
In February, Mary Beery, quilt teacher from the Clothes Line (now Patchwork Plus) fabric store in Dayton, was the speaker and 70 people arrived to overfill the Library room capacity of 50!
In March of the same year, we moved to a larger room at Mack Truck Company. In appreciation for the use of their room, we made a "Trip Around the World" wall hanging with an appliquéd bulldog. A bulldog is the logo for Mack Trucks. This quilt still hangs in their lobby.
There were only 5 officers – President, V. President, Treasurer, Secretary, Editor
Lisa McCumsey won the competition for a Guild logo and name tag.
Nancy Pearson was the first out-of-town speaker/teacher, who came all the way from Illinois to conduct 2 workshops on appliqué.
The Guild started selling SVQG Pins for $3 each.
The raffle quilt was donated by Dorothy Williams and won by Ellen Layman. The next raffle quilt was donated by Terry Wessel.

\section{\label{sec:introduction}Introduction}
	In recent studies, the chaotic behavior of quantum systems has been investigated from different viewpoints\cite{Steinberg2019,Roberts2016,Cotler2017}. A common property of chaotic systems is that during unitary time evolution, simple operators can become highly complicated. This leads to the scrambling of information stored in local operator\cite{Zhou2018}. This phenomena is investigated in different contexts i.e., random matrix theory\cite{Bohigas1984}, black holes\cite{Cotler2017} and quantum thermalisation\cite{Srednicki1994,Deutsch1991}.

	There are multiple ways to characterize chaos and information scrambling e.g. operator entanglement entropy or out-of-time-ordered commutator (OTOC)\cite{Prosen2007,Hashimoto2017}. In this paper, we are focusing on the latter which was originally introduced by Larkin and Ovchinnikov in 1969 in a calculation of the non-linear correction to the conductivity of a dirty superconductor \cite{Ovchinnikov1969}. The OTOC can be considered as the second moment of the commutator, defined as
	\begin{equation}
	C(t)=-\left\langle\left[W(t),V(0)\right]^2\right\rangle\geq 0,
	\label{eq:otocgen}
	\end{equation}
	where $W$ and $V$ are local operators possibly separated by finite distance and $W(t)=\exp(iHt)W\exp(-iHt)$ denotes the Heisenberg time evolution.

	The OTOC is a useful tool to measure the sensitivity of the time evolution of the system on the initial conditions\cite{Roberts2016} and to characterize information spreading processes. The information stored in local operators are spreading over many degrees of freedom during the time evolution and cannot be restored by local measurements\cite{Page1993}. This process i.e., the loss of information through delocalization is called scrambling\cite{Lashkari2013,Sekino2008}. In systems, where the short time exponential growth, bounded by thermal Lyapunov exponent $\lambda_L\leq 2\pi k_BT$ \cite{Roberts2016,Maldacena2016,Tsuji2018} is present are called fast scramblers, but there are also models where this short time growth is absent, called slow scramblers. Thus, a possible way to understand the nature of chaos and test capabilities of condensed matter systems for quantum information processing is to investigate the temporal behavior of OTOC. It has already been analyzed in a variety of systems, including Luttinger liquids\cite{Dra2017}, random unitary circuits\cite{Nahum2018,Rakovszky2018,vonKeyserlingk2018} in quantum Ising chain\cite{Lin2018}, XY chains\cite{Jiahui2019}, conformal field theories \cite{Roberts2015,Stanford2016} and Sachdev-Ye-Kitaev model\cite{Sachdev1993,Maldacena20162,Tsuji2017}. OTOC has been investigated experimentally as well in different many-body systems such as in cold atomic systems, trapped ions or in a nuclear magnetic resonance quantum simulator\cite{Li2017,Swingle2016,Zhu2016,Kaufman2016,Grttner2017,Landsman2019,Xinfang2019}.

	In this paper, we consider Dirac--Weyl systems in one, two and three dimensions, characterized by linear energy-momentum relation. These models are popular not only in the condensed matter physics but possess a rich history in high energy physics as well\cite{Kharzeev2009}. As already mentioned, the common property of these systems is the linear energy-momentum dispersion relation and the Brillouin zone contains monopole-like structures called Weyl or Dirac nodes. The most famous descendants are carbon nanotubes in one, graphene in two and Weyl-semimetals in three dimensions \cite{Armitage2018,CastroNeto2009}, respectively. The low energy excitations are described by massless non-interacting fermions and one of their unique features is that they can host topologically non-trivial states which are robust against small perturbations \cite{Okuyama2018,Hasan2010,Armitage2018}. This non-trivial topology shows up in exotic electromagnetic transport phenomena such as topologically protected edge states in zigzag carbon nanotubes in presence of spin-orbit interaction\cite{Okuyama2018}, the quantum spin Hall effect in graphene\cite{Kane2005} or the chiral anomaly \cite{Goswami2013,Vishwanath2013} or the anomalous Hall conductivity in Weyl semimetals \cite{Burkov2011}.

	To obtain the short and late time behavior of the OTOC, we rewrite Eq. (\ref{eq:otocgen}) in a more suggestive way as

	\begin{equation}
	C(t)=-\left\langle\left[W(t),V(0)\right]\right\rangle^2+K(t)
	\label{eq:otocgen2}
	\end{equation}
	where the first term is the square of the expectation value of the spin commutator and $K(t)$ is the variance of the commutator, i.e. $K(t)=\left\langle\left[W(t),V(0)\right]\right\rangle^2-\left\langle\left[W(t),V(0)\right]^2\right\rangle$. In other words, $K(t)$ measures the spreading of the probability distribution of the commutator compared to its expectation value. When the commutator as an operator is a c-number, the variance is zero\cite{Dra2017} which means the distribution of the commutator is a Dirac-delta function. A finite variance is the first indicator of the broadening of the distribution around the mean value. In our case, this indicates how the OTOC, i.e. the expectation value of the square of the commutator differs from the square of the expectation value of the commutator. One can in principle also obtain the full counting statistics of the commutator in general by calculating higher moments as $\langle\left[W(t), V(0)\right]^n \rangle$ in a similar way as in Eq. (\ref{eq:otocgen}).

	In this work, we investigate the short and late time behavior of OTOC in Dirac--Weyl systems. In this context, the OTOC was already investigated in interacting graphene\cite{klug} Weyl semimetals\cite{Chen2019} from different approaches. We are focusing on the response of a single non-interacting Dirac--Weyl cone which is diagonalizable straightforwardly, thus integrable. The short time behavior of OTOC gives a universal $t^2$ initial rise from both the square of the expectation value of the commutator and the variance from Eq. \eqref{eq:otocgen2}, though the contribution of the former parametrically is dominant over the latter. The late time decay is dominated only by $K(t)$ and depends on the dimension of the system and is independent of the chemical potential.

	This paper is organized as follows: in Sec. \ref{sec:hamiltonian}, we introduce the model Hamiltonian and the operators used for further calculations. In Sec. \ref{sec:respose}, the time-dependent expectation value of the spin commutator is calculated by separating the matrix element and occupation number dependent parts. In Sec. \ref{sec:otoc} calculation procedure of OTOC is outlined and briefly discuss the results. In Sec. \ref{sec:summary}, our main results are summarized.

	\section{\label{sec:hamiltonian}Low energy effective Hamiltonian}

	The low energy effective Hamiltonian of Dirac--Weyl systems in $d$ dimension is given by

	\begin{equation}
	H=v_\text{F}\mathbf{p}\cdot\boldsymbol{\sigma}
	\label{eq:ham}
	\end{equation}
	where $\textbf{p}$ is the momentum operator, $v_\text{F}$ is the Fermi velocity and $\boldsymbol{\sigma}$ denotes the corresponding Pauli matrices. For $d=1$ only $\sigma_{x}$ appears in the Hamiltonian, for $d=2$, $\boldsymbol{\sigma}=\left[\sigma_{x},\sigma_{y}\right]$ and for three dimensions all Pauli matrices are present. At low energy, the energy dispersion relation is linear in momentum for any dimension: $\varepsilon_{\lambda}(\mathbf{k})=\lambda\hbar v_\text{F}|\mathbf{k}|$ with $\lambda=\pm$ the band index\cite{CastroNeto2009,Armitage2018}. The corresponding wavefunctions are written as

	\begin{equation}
	\phi_{\lambda,\mathbf{k}}(\mathbf{r})=\frac{1}{\sqrt{V_{d}}}e^{i\mathbf{kr}}\left|k,\lambda\right\rangle,
	\label{eq:wavefunc}
	\end{equation}
	where $V_{d}$ is the volume and  $\left|k,\lambda\right\rangle$ is the normalized eigenspinor written in $d$ dimension as

	\begin{gather}
		\left|k,\lambda\right\rangle=
		\begin{cases}
			\frac{1}{\sqrt{2}}
			\begin{bmatrix}
				1 \\
				\lambda
			\end{bmatrix} &\text{for } d=1,\vspace{1mm}\\
			\frac{1}{\sqrt{2}}
			\begin{bmatrix}
				\lambda \\
				e^{i\varphi_{k}}
			\end{bmatrix} &\text{for } d=2,\vspace{1mm}\\
			\begin{bmatrix}
				\cos{\left(\frac{\vartheta_{k}+(\lambda-1)\pi/2}{2}\right)} \\
				\sin{\left(\frac{\vartheta_{k}+(\lambda-1)\pi/2}{2}\right)}e^{i\varphi_{ k}} \\
			\end{bmatrix} &\text{for } d=3.
		\end{cases}
		\label{eq:spinors}
	\end{gather}
	Here $\varphi_{k}$ is the polar angle in two and the azimuthal angle in three dimensions and $\vartheta_{k}$ is the polar angle in 3D. Using Eq. (\ref{eq:wavefunc}), we construct the local field operators. Considering a Hermitian operator $\mathcal{O}$, the spatial and time dependent formula in second quantized formalism is given by\cite{Mahan2000}

	\begin{equation}
	\mathcal{O}({\bf r},t)=\frac{1}{V_{d}}\sum_{k_{1},k_{2}}e^{i{\bf (k_1-k_2)r}}T(k_1,k_2)
	\left\langle k_2|\mathcal{O}|k_1\right\rangle c^{\dagger}_{k_2}c_{k_1}.
	\label{eq:secop}
	\end{equation}
	Here,  $k_{i}=({\bf k_{i}},\lambda_i)$ is a combination of the momentum state and band index, and  $c^{\dagger}_{k_2}$ and $c_{k_1}$ are fermionic creation and annihilation operators into state $k_2$ and $k_1$, respectively. The time dependence is represented by $T(k_1,k_2)=\exp\left[i(\varepsilon_{\lambda_2}(\mathbf{k}_2)-\varepsilon_{\lambda_1}(\mathbf{k}_1))t\right]$ with $\varepsilon_{\lambda_i}(\mathbf{k}_i)$, the energy of the Dirac--Weyl fermions and $\left\langle k_2|\mathcal{O}|k_1\right\rangle$ is the corresponding matrix element of $\mathcal{O}$ operator. In the following sections, we are focusing on the expectation value the spin commutators and the corresponding OTOC for spatially identical spin operators, thus we set $\textbf{r}=0$ in Eq. (\ref{eq:secop}) during the calculations.

	\section{\label{sec:respose}Spin correlation function}
	The correlation function of two spin operators $\sigma_{\alpha}(0,t)$ are related to linear response and defined by the standard Kubo formula as\cite{Giuliani2005}

	\begin{equation}
	\Pi^{\alpha\beta}(t)=i\left\langle\left[\sigma_{\alpha} (0,t),\sigma_{\beta} (0,0)\right]\right\rangle\Theta(t).
	\label{eq:kubo}
	\end{equation}
	Here, $\Theta(t)$ is the Heaviside step function and $\alpha,\beta=x,y,z$. For diagonal case, when $\alpha=\beta$ the expectation value of the commutator is

	\begin{equation}
	\Pi^{\alpha\alpha}(t)= \frac{i}{V_{d}^2}\sum_{k_1,k_2}T(k_1,k_2)\left|\left\langle k_2|\sigma_{\alpha}|k_1\right\rangle\right|^2\left[f(k_2)-f(k_1)\right],
	\label{eq:kuboexp}
	\end{equation}
	for $t>0$ and $f(k_i)=\left[\exp((\varepsilon_{\lambda_i}(\mathbf{k}_i)-\mu)/k_\text{B} T)+1\right]^{-1}$ is the Fermi function. Eq. (\ref{eq:kuboexp}) consists of two terms, the occupation number dependent part and the absolute value square of the matrix elements. These two terms are treated separately in the followings.

	\subsection{\label{sec:matrix}Matrix elements}

	By rewriting the appropriate polar and azimuthal coordinates of the eigenspinors in Eq. (\ref{eq:spinors}) to Cartesian coordinates of momentum vector, the square of matrix elements in Eq. (\ref{eq:kuboexp}) has a closed formula in $d$ dimension given by

	\begin{equation}
	\left|\left\langle k_2|\sigma_{\alpha}|k_1\right\rangle\right|^2=\frac{1}{2}\left[1-\lambda_1 \lambda_2\frac{{\bf k_1 k_2}-2k_{1,\alpha}k_{2,\alpha}}{|{\bf k_1}||{\bf k_2}|}\right].
	\label{eq:matsquare}
	\end{equation}
	In one dimension, there are no angular integrals and Eq. (\ref{eq:matsquare}) gives only Kronecker delta function as: $\left|\left\langle k_2|\sigma_{x}|k_1\right\rangle\right|^2=\delta_{\lambda,\lambda'}$ and $\left|\left\langle k_2|\sigma_{y,z}|k_1\right\rangle\right|^2=1-\delta_{\lambda,\lambda'}$. Rewriting the summations into spherical integrals in Eq. (\ref{eq:kuboexp}), we  evaluate the angular integrals separately since only the square of matrix elements in Eq. \eqref{eq:matsquare} depends on angular variables and are independent from the absolute value of momentum. In two and three dimensions, the integrals over angular variables are

	\begin{equation}
	M^{\alpha}_d(k_1,k_2)=\int\frac{d\Omega_1 d\Omega_2}{(2\pi)^{2(d-1)}}\left|\left\langle k_2|\sigma_{\alpha}|k_1\right\rangle\right|^2,
	\label{eq:intmatsquare}
	\end{equation}
	where $d\Omega_i=d\varphi_{k_i}$ in two and $d\Omega_i=d\varphi_{k_i}\sin(\vartheta_{k_i})d\vartheta_{k_i}$ in three dimensions with $i=1,2$. In one dimension, there is no angular integral, but we can still introduce $M^{\alpha}_1(k_1,k_2)$ by changing the boundary of the momentum integrals from $(-\infty,\infty)$ to $[0,\infty)$. Evaluating the integrals, we end up with

	\begin{equation}
	M^{\alpha}_1(k_1,k_2)=2, ~M^{\alpha}_2(k_1,k_2)=\frac{1}{2}, ~M^{\alpha}_3(k_1,k_2)=\frac{2}{(2\pi)^2}.
	\label{eq:mat}
	\end{equation}
	The angular integral of the square of matrix elements yields a band index ($\lambda$) independent constant what we use in the next section to derive the time dependence of the expectation value of the commutator.

	\subsection{\label{sec:expresp}Explicit form of the expectation value of the commutator}

	We evaluate the remaining integrals over the radial component of momentum. Let us introduce the following functions as

	\begin{align}
		G_{d}^{<}(t)&=\frac{1}{2\pi}\sum_{\lambda_1}\int_{0}^{\infty}dk~k^{d-1}T(k_1,0)f(k_1)e^{-\delta k}
		\label{eq:greenless}\\
		G_{d}^{>}(t)&=\frac{1}{2\pi}\sum_{\lambda_1}\int_{0}^{\infty}dk~k^{d-1}T(k_1,0)(1-f(k_1))e^{-\delta k}.
		\label{eq:greengreat}
	\end{align}
	Here, $dk$ denotes the integral over the radial component of  the momentum and $\delta$ is the exponential cutoff which is a commonly used cutoff scheme in field theories \cite{Giuliani2005}. The functions defined in Eqs. (\ref{eq:greenless}) and (\ref{eq:greengreat}) are practically the greater and lesser Green's functions\cite{Mahan2000, Rammer1986} with the only difference that instead of summing over the full momentum space, only the  radial component is integrated over.

	We express the expectation value of the commutator in terms of these Green's functions as

	\begin{equation}
	\Pi^{\alpha\alpha}(t)=-2M^{\alpha}_d(k_1,k_2)\text{Im}\left[G_{d}^{>}(t)\bar{G}_{d}^{<}(t)\right].
	\label{eq:kubogreen}
	\end{equation}
	We are interested in the zero temperature limit, allowing us to substitute the Fermi function with a Heaviside step function. In these non-interacting systems, no exponential growth with thermal Lyapunov exponent is expected, which justifies this simplification. The integral defined in the Green's functions can be evaluated, the detailed derivation is presented in Appendix \ref{app:appa}. After some straightforward algebra, the commutator looks as

	\begin{widetext}
		\begin{gather}
			\Pi^{\alpha\alpha}(\tau)=\text{sgn}(\mu)\times
			\begin{cases}
				\dfrac{8}{(2\pi)^2\delta^2}\dfrac{e^{-\nu}}{(\tau^2+1)^2}\left[\sin(\nu \tau)+\tau \cos(\nu \tau)\right] &\text{for } d=1,\vspace{2mm}\\
				\dfrac{2e^{-\nu}}{(2\pi)^2\delta^4}\dfrac{\tau^2-1}{\left(\tau^2+1\right)^4}\left[\left((1-\nu)\tau^2-(1+\nu)\right)\sin(\nu\tau)-\tau\left(\nu \tau^2+(2+\nu)\right)\cos(\nu \tau)\right] &\text{for } d=2,\vspace{2mm}\\
				\dfrac{16e^{-\nu}}{ (2\pi)^4\delta^6}\dfrac{3\tau^2-1}{\left(\tau^2+1\right)^6}\Big[\left[\nu(2-\nu)\tau^4+(6-2\nu^2)\tau^2-(\nu^2+2\nu+2)\right]\sin(\nu\tau)- \\
				-\left[\nu^2\tau^5-(2\nu^2+4\nu-2)\tau^3+(\nu^2+4\nu+6)\tau \right]\cos\left(\nu\tau\right)\Big] &\text{for } d=3.
			\end{cases}
			\label{eq:kuboe}
		\end{gather}
	\end{widetext}
	Here, we introduced dimensionless variable for time as $\tau= v_{\text{F}}t/\delta$ and  $\nu=|\mu|\delta/ v_\text{F}$ for chemical potential with $ v_{\text{F}}/\delta$, the high energy cutoff.

	The spin correlation functions with respect to time can be separated into three distinct regions: short time growth for $\tau \ll 1$, an intermediate time window for $1\ll \tau \ll 1/\nu$ and the late time decay when $\tau \gg 1/\nu$.
	Since the chemical potential always lies below the high energy cutoff, we use  $\nu\ll 1$.

	For short times, the correlation function grows linearly with time in all considered dimension. This short time linear behavior is shown in Fig. \ref{fig:kuboshort}. The intermediate time window which also represents the late time decay for the $\nu=0$ case is depicted in Fig. \ref{fig:kuboshort}. The exponents of power-law decay can be obtained by calculating the asymptotic behavior of the rational function in Eq. (\ref{eq:kuboe}) and taking the $\nu\tau \to 0$ for the trigonometric terms. As a result, the decay in $d$ dimensions is given by $\sim\tau^{-(2d+1)}$. For the third case with $\tau \gg 1/\nu$, the asymptotic behavior is obtained as $\sim\nu^{d-1}\cos(\nu\tau)/\tau^{(2(d-1)!+1)}$  with $!$ denoting the factorial function. We collected the short, intermediate and late time behaviors of the expectation value of the spin-spin commutator in Table \ref{tab:kubo} and displayed them in Fig. \ref{fig:kuboshort}.

	\begin{figure}[!ht]
		\includegraphics[width=\linewidth]{kubo}

The solid and dashed lines represent the $\nu=0$ and $\nu=0.05$ case, respectively. In any dimension, the early time growth scales with $\tau$. For intermediate times, the temporal decay exponent differs from the late time exponent for $d=2$ and $3$, which is apparent in the intermediate time window. For late times, the response decays as a power-law whose exponent depends on the chemical potential and the dimension. The black dash-dotted lines  are $\tau^{-3}$, $\tau^{-5}$ and $\tau^{-7}$ representing the possible intermediate and late time decay, respectively.}

	\section{\label{sec:otoc} Out-of-time-ordered commutator}

	The Dirac--Weyl systems are simple integrable models, thus  OTOC is expected to display a $\sim t^2$ initial growth and a power-law decay for late times. Using Eq. (\ref{eq:otocgen}), the OTOC for spatially non-separated spin operators is given by

	\begin{eqnarray}
	C_{\alpha\alpha}(t)= -\frac{1}{V_{d}^4}\sum_{\substack{k_1,k_2,\\ k_3}} \sum_{\substack{l_1,l_2,\\l_3}}T(k_1,k_2)T(l_1,l_2) \times \nonumber\\
	\times [\left \langle k_2|\sigma_\alpha|k_1\right\rangle
	\left \langle k_1|\sigma_\alpha|k_3\right\rangle
	\left \langle l_2|\sigma_\alpha|l_1\right\rangle
	\left \langle l_1|\sigma_\alpha|l_3\right\rangle
	\langle a^{\dagger}_{k_2}a_{k_3}a^{\dagger}_{l_2}a_{l_3}\rangle\nonumber\\
	-\left \langle k_2|\sigma_\alpha|k_1\right\rangle
	\left \langle k_1|\sigma_\alpha|k_3\right\rangle
	\left \langle l_2|\sigma_\alpha|l_1\right\rangle
	\left \langle l_3|\sigma_\alpha|l_2\right\rangle
	\langle a^{\dagger}_{k_2}a_{k_3}a^{\dagger}_{l_3}a_{l_1}\rangle\nonumber\\
	-\left \langle k_2|\sigma_\alpha|k_1\right\rangle
	\left \langle k_3|\sigma_\alpha|k_2\right\rangle
	\left \langle l_2|\sigma_\alpha|l_1\right\rangle
	\left \langle l_1|\sigma_\alpha|l_3\right\rangle
	\langle a^{\dagger}_{k_3}a_{k_1}a^{\dagger}_{l_2}a_{l_3}\rangle\nonumber\\
	+\left \langle k_2|\sigma_\alpha|k_1\right\rangle
	\left \langle k_3|\sigma_\alpha|k_2\right\rangle
	\left \langle l_2|\sigma_\alpha|l_1\right\rangle
	\left \langle l_3|\sigma_\alpha|l_2\right\rangle
	\langle a^{\dagger}_{k_3}a_{k_1}a^{\dagger}_{l_3}a_{l_1}\rangle].\nonumber\\
	\label{eq:otoc}
	\end{eqnarray}
	Here, $\alpha=x,y,z$ denotes the component of the spin. By using Wick's theorem, the expectation value of four  fermionic operators is

	\begin{eqnarray}
	\left\langle a^{\dagger}_{k_1}a_{k_2}a^{\dagger}_{k_3}a_{k_4}\right\rangle=\delta_{k_1,k_2}\delta_{k_3,k_4}f(k_1)f(k_3)\nonumber\\
	+\delta_{k_1,k_4}\delta_{k_3,k_2}f(k_1)[1-f(k_3)].
	\label{eq:fourexp}
	\end{eqnarray}
	The commutator can be split into two parts, the first and second one containing  $f(k_i)f(l_j)$ and $f(k_i)[1-f(l_j)]$ terms, respectively. The first part gives the square of the expectation value of the commutator, defined in Eq. (\ref{eq:kuboexp}), thus the OTOC looks as

	\begin{equation}
	C_{\alpha\alpha}(t)= -\left\langle\left[\sigma_\alpha (t),\sigma_\alpha \right]\right\rangle^2+K_{\alpha\alpha}(t),
	\label{eq:otocgen1}
	\end{equation}
	where $K_{\alpha\alpha}(t)$ is the variance of the commutator. It is given by

	\begin{eqnarray}
	K_{\alpha\alpha}(t)=-\frac{1}{V^4}\sum_{\substack{k_1,k_2,\\ l_1,l_2}}
	\left \langle k_2|\sigma_\alpha|k_1\right\rangle
	\left \langle k_1|\sigma_\alpha|l_2\right\rangle\times\nonumber\\
	\times\left \langle l_2|\sigma_\alpha|l_1\right\rangle
	\left \langle l_1|\sigma_\alpha|k_2\right\rangle\times\nonumber\\
	\times \Big(T(k_1,k_2)T(l_1,l_2)[f(k_2)[1-f(l_2)]+f(k_1)[1-f(l_1)]]\nonumber\\
	-T(k_1,l_1)[f(k_2)(1-f(l_2))+f(l_2)(1-f(k_2))]\Big).\nonumber\\
	\label{eq:otoccorr}
	\end{eqnarray}

	The product of the matrix elements is treated separately from remaining terms, and the integral over the angular variables, denoted by $N^{\alpha}_d(k_1,k_2)$ gives

	\begin{equation}
	N^{\alpha}_d(k_1,k_2)=\frac{\left(M^{\alpha}_d(k_1,k_2)\right)^2}{2},
	\label{eq:otocmatelem}
	\end{equation}
	where $M^{\alpha}_d(k_1,k_2)$ is defined in Eq. (\ref{eq:mat}). The remaining terms depend only the radial component of the momentum. Using Eq. (\ref{eq:greenless}) and Eq. (\ref{eq:greengreat}), we can rewrite the variance in Eq. (\ref{eq:otoccorr}) as

	\begin{eqnarray}
	K_{\alpha\alpha}(t)=2N^{\alpha}_d\Big(\left|G^{>}_{d}(t)+G^{<}_{d}(t)\right|^2\Big(\text{Re}\left[G^{>}_{d}(0^+)\bar{G}^{<}_{d}(0^+)\right]\nonumber\\
	-\text{Re}\left[G^{>}_{d}(t)\bar{G}^{<}_{d}(t)\right]\Big)-2\left(\text{Im}\left[G^{>}_{d}(t)\bar{G}^{<}_{d}(t)\right]\right)^2 \Big).\nonumber\\
	\label{eq:otoccorr2}
	\end{eqnarray}
	Here $G^{</>}_{d}(0^+)=\lim_{t\to 0^{+}}G^{</>}_{d}(t)$ and $N^{\alpha}_d$ is the prefactor coming from Eq. (\ref{eq:otocmatelem}). The detailed derivation is presented in Appendix \ref{app:appa}. Evaluating the integrals yields the variance as

	\begin{widetext}

		\end{gather}
	\end{widetext}

	Here, we used again the dimensionless variables for time ($\tau$) and the chemical potential ($\nu$).

	Eq. \eqref{eq:otoce} allows us to investigate the short and late time behavior of the OTOC, similarly to the case of the commutator in Eq. \eqref{eq:kuboe}. The natural energy scales in the problem are $\mu$ and $v_\text{F}/\delta$, translating into three separate temporal windows for short, intermediate and late times as $\tau\ll 1$, $1\ll\tau\ll 1/\nu$ and $1/\nu\ll\tau$, respectively. For short times, the OTOC grows with $\tau^2$ also shown in Fig. \ref{fig:otocshort}. This behavior follows from a Baker-Campbell-Hausdorff expansion of $\sigma_\alpha(t)$ with the nested commutators \cite{Dra2017,Roberts2016}

	\begin{equation}
	\sigma_\alpha(t)=\sigma_\alpha+it \left[H,\sigma_\alpha\right]+\frac{(it)^2}{2!}\left[ H,\left[H,\sigma_\alpha\right]\right]+\dots
	\label{eq:hausdorf}
	\end{equation}
	The contribution of the first term in Eq. (\ref{eq:hausdorf}) gives trivially vanishing contribution to both the expectation value of the commutator and the OTOC. The $\tau^2$ growth arises from the second term in Eq. (\ref{eq:hausdorf}) with the coefficient $\langle\left[\left[H,\sigma_\alpha\right],\sigma_\alpha\right]^2\rangle$. This short time growth originates from both the  square of the expectation value of the commutator and the variance of the commutator in Eq. (\ref{eq:otoce}).

	We note that the second term in Eq. (\ref{eq:hausdorf}) is also responsible for the linear growth of the response function for short times and it ensures that both the linear response and the OTOC have to be real since $H$ and $\sigma_\alpha$ are Hermitian operators, thus the expectation value of their commutator has to be real.

	For intermediate and late times, the OTOC decays in an identical power-law fashion, shown in Fig. \ref{fig:otocshort}. Irrespective of the value of $\nu$, the asymptotics of the temporal decay is $\sim \tau^{-4(d-1)!}$ with $!$ denoting the factorial function which is the same result as we obtained for late times. This means the exponent of the power-law decay is independent of the chemical potential and depends only on the spatial dimension of the system. This behavior comes from the time-independent part of Eq. (\ref{eq:otoccorr2}) i.e., $\text{Re}\left[G^{>}_{d}(0^+)\bar{G}^{<}_{d}(0^+)\right]$. The short and late time behaviors are represented in Table \ref{tab:otoc}.

	\begin{figure}[!ht]

The solid and dashed lines represent the $\nu=0$ and $\nu=0.2$ case, respectively. For short times, OTOC exhibits $\tau^2$ growth with a chemical potential dependent prefactor. For intermediate and late times it decays as a power-law with an exponent depending only on the spatial dimension. In contrast with the correlation function, there is no difference in the decay for intermediate and late times. The black dash-dotted lines are $\tau^{-4}$ and $\tau^{-8}$ functions.}

			\end{tabular}
		\end{ruledtabular}
		\caption{\label{tab:otoc} Characteristic time dependence of OTOC for short, intermediate and late times. For the latter two, the behaviour is identical, though.}
	\end{table}

	The influence of the variance on  OTOC is plotted in Fig. \ref{fig:var}. For short times, both the square of expectation value of the commutator and the variance scales with $\tau^2$ but former parametrically is dominant over the latter. This can be seen in Fig. \ref{fig:var} since the $K_{\alpha\alpha}(\tau)/C_{\alpha\alpha}(\tau)$ ratio is small for $\tau \ll 1$.
	For intermediate and late times, the ratio tends to one, independently of the chemical potential, indicating  that the OTOC is dominated by the variance in this regime.

	\begin{figure}[!ht]
		\includegraphics[width=\linewidth]{variance}
		\caption{\label{fig:var}  Ratio of the variance and OTOC as a function of time. The solid and dashed lines represent the $\nu=0$ and $\nu=0.2$ case, respectively. For $\tau \ll 1 $, the main contribution to OTOC comes from the square of the expectation value of the
commutator, while when $\tau \gg 1 $ the variance dominates.}
	\end{figure}

	In general, the quantum butterfly effect shows up in systems with exponential growth of the OTOC at short times and a large late time value\cite{Roberts20152,Roberts2016,Maldacena2016}. For non-interacting Dirac-Weyl systems, the OTOC scales with $\tau^2$ initially, i.e. with the lowest possible power and no exponential growth is identified.
	The late time OTOC vanishes which agrees with the general expectations since our models are non-interacting without any chaotic feature. This means the information encoded in local operators is lost slowly through time evolution\cite{Huang2016,Chen2016}. The same short time behavior was identified in different integrable models like Heisenberg XXZ chain\cite{Dra2017}, quantum Ising chain\cite{Lin2018}, and XY chain\cite{Jiahui2019}. These models also exhibit late time power-law decay, similarly to our findings, though the exponents depend on the actual system.

	\section{\label{sec:summary}Summary}

	In this work, we have investigated dynamics of the expectation value of the spin commutators and the corresponding OTOC in Dirac--Weyl systems in $d=1$, $2$ and $3$ dimensions. Three distinct temporal regions are identified during time evolution. For short times, $\tau \ll 1$, we obtain a linear initial rise in time.  For intermediate times, when $1\ll \tau\ll1/\nu$ the expectation value of the commutator starts to decay with power-law as $\sim\tau^{-(2d+1)}$. In the late time regime, the commutator decays with  $\sim\nu^{d-1}\cos(\nu\tau)/\tau^{(2(d-1)!+1)}$ for finite doping.

	The OTOC of local spin operators displays robust behavior, mostly independent of chemical potential. For short times, the OTOC grows with $\tau^2$, the lowest possible power, while for late times, it decays with $\tau^{-(4(d-1)!)}$ for all spin components. We note that the decay in the intermediate time window coincides with that for late times. The short time behavior is determined by both the square of the expectation value of the commutator and the variance while for late times the variance gives the dominant part. The power-law growth for short times and the vanishing late time value indicate that these systems are slow information scramblers. These results are essential when the effect of other sources of information scrambling (interaction, disorder) are analyzed on top of the non-interacting results.

Q: Designing a Test class for a custom Barrier I had to do an implementation of a custom barrier class using locks as part of my course work.
To test my LockBarrier class, I came up with a the following test code. It is working correctly, but I am concerned whether that is the proper way to do. Could you please suggest improvements I can do, especially structuring the classes. I think my way of coding is not the correct one. Any suggestions are welcome.
public class TestDriver
{
        private static LockBarrier barrier;

        static class Runnable1 implements Runnable
        {
            public Runnable1()
            { }

            public void run()
            {
                try
                {
                    System.out.println(Thread.currentThread().getId()+" lazy arrived at barrier");
                    Thread.sleep(10000);
                    barrier.await();
                    System.out.println(Thread.currentThread().getId()+" passed barrier");

                }
                catch (InterruptedException ie)
                {
                    System.out.println(ie);
                }
            }

        }

        static class Runnable2 implements Runnable
        {

            public Runnable2()

            public void run()
            {
                try
                {

                    //barrier.await(1,TimeUnit.SECONDS);
                    barrier.await();

        static class Runnable3 implements Runnable
        {
            public Runnable3()
            { }

            public void run()
            {
                try
                {
                    System.out.println(Thread.currentThread().getId()+" very lazy arrived at barrier");
                    Thread.sleep(20000);
                    barrier.await();
                    System.out.println(Thread.currentThread().getId()+" passed barrier");
                }
                catch (InterruptedException ie)
                {
                    System.out.println(ie);
                }
            }
        }

        public static void main(String[] args) throws InterruptedException
        {
            barrier = new LockBarrier(3);
            Thread t1 = new Thread(new TestDriver.Runnable1());
            Thread t2 = new Thread(new TestDriver.Runnable2());
            Thread t3 = new Thread(new TestDriver.Runnable3());
            t1.start();
            t2.start();
            t3.start();

            t1.join();
            t2.join();
            t3.join();
        }
}

A: Seperating Concurrency for your Class
Testing stuff concurrently is hard (tm)! GOOS amongst other people recommending separating the concurrency part from the parts that are doing some work. So, for example, if you had some Scheduler which is supposed to schedule some task on one or more threads. You can pass in the part that is responsible for the threading to your scheduler and just test the scheduler collaborates with this object correctly. This is more in a classic unit testing style.
An example with a `Scheduler is here, this uses a mocking framework to help. If you're not familiar with those ideas, don't worry, they're probably not relevant for your test.
Having said that, you might actually want to run your class 'in context' in a multi-threaded way. This seems to be the kind of test you're writing above. The trick here is to keep the test deterministic. Well, I say that, theres a couple of choices.
Deterministic
If you can setup your test to progress in a deterministic way, waiting at key points for conditions to be met before moving forward, you can try to simulate a specific condition to test. This means understanding exactly what you want to test (for example, forcing the code into a deadlock) and stepping through deterministically (for example, using abstractions like CountdownLatches etc to 'synchronise' the moving parts).
When you attempt to make some multi-threaded test syncrhonise its moving parts, you can use whatever concurrency abstraction is available to you but it's difficult because its concurrent; things could happen in an unexpected order. You're trying to mitegate this in your test by using the sleep calls. We generally don't like to sleep in a test because it'll make the test run slower and when you've got thousands of tests to run, every ms counts. If you lower the sleep period too much the test become non-deterministic and ordering isn't guaranteed.
Some examples include

*

*Forcing a deadlock using CountdownLatch

*Setting up a thread to be interuptted
You've spotted one of the gotchas where the main test thread will finish before the newly spawned threads under test complete (using the join). Another way is to wait for a condition, for example using WaitFor.
Soak / Load Testing
Another choice is to setup a test to setup, run and spam your classes in an attempt to overload them and force them to betray some subtle concurrency issue. Here, just as in the other style, you'll need to setup up specific assertion so that you can tell if and when the classes did betray themselves.
For you're test then, I'd suggest coming up with an assertion so that you can see both positive and negative runs against your class and replacing the sleep (and system.out calls. If you can, running your test from something like JUnit is more idiosyncratic.
For example, a basic test in the style you've started down might look like this
public class TestDriver {

    private static final CyclicBarrier barrier = new CyclicBarrier(3);
    private static final AtomicInteger counter = new AtomicInteger(0);

    static class Runnable1 implements Runnable {
        public void run() {
            try {
                barrier.await();
                counter.getAndIncrement();
            } catch (Exception ie) {
                throw new RuntimeException();
            }
        }

    }

    @Test (timeout = 200)
    public void shouldContinueAfterBarrier() throws InterruptedException {
        Thread t1 = new Thread(new Runnable1());
        Thread t2 = new Thread(new Runnable1());
        Thread t3 = new Thread(new Runnable1());
        t1.start();
        t2.start();
        t3.start();
        t1.join();
        t2.join();
        t3.join();
        assertThat(counter.get(), is(3));
    }
}

If possible, adding a timeout to your Barrier is good practice and would help write a negative test like this
public class TestDriver {

    private static final CyclicBarrier barrier = new CyclicBarrier(3);
    private static final AtomicInteger counter = new AtomicInteger(0);

    static class Runnable1 implements Runnable {
        public void run() {
            try {
                barrier.await(10, MILLISECONDS);
                counter.getAndIncrement();
            } catch (Exception ie) {
                throw new RuntimeException();
            }
        }
    }

    @Test (timeout = 200)
    public void shouldTimeoutIfLastBarrierNotReached() throws InterruptedException {
        Thread t1 = new Thread(new Runnable1());
        Thread t2 = new Thread(new Runnable1());
        t1.start();
        t2.start();
        t1.join();
        t2.join();
        assertThat(counter.get(), is(not((3))));
    }

}

If you wanted to post your implementation, we might be able to suggest more alternatives. Hope that gives you some ideas though...
EDIT: Another choice is to reach into your barrier object for finer grained assertions, for example,
@Test (timeout = 200)
public void shouldContinueAfterBarrier() throws InterruptedException, TimeoutException {
    Thread t1 = new Thread(new BarrierThread(barrier));
    Thread t2 = new Thread(new BarrierThread(barrier));
    Thread t3 = new Thread(new BarrierThread(barrier));
    assertThat(barrier.getNumberWaiting(), is(0));
    t1.start();
    t2.start();
    waitForBarrier(2);
    t3.start();
    waitForBarrier(0);
}

private static void waitForBarrier(final int barrierCount) throws InterruptedException, TimeoutException {
    waitOrTimeout(new Condition() {
        @Override
        public boolean isSatisfied() {
            return barrier.getNumberWaiting() == barrierCount;
        }
    }, timeout(millis(500)));
}

EDIT: I wrote some of this up at http://tempusfugitlibrary.org/recipes/2012/05/20/testing-concurrent-code/

A: The code looks good to me. Maybe you can pass the LockBarrier to the Runnable instead of declaring it outside.

Study suggests link between word choices and extraverts
Washington [US], December 31 (ANI): A study by a team of Nanyang Technological University, Singapore (NTU Singapore) psychologists has found a link between extraverts and their word choices.
The finding highlights the need for stronger linguistic indicators to be developed for use in online personality prediction tools, which are being rapidly adopted by companies to improve digital marketing strategies.
Today, marketing companies use predictive algorithms to help them forecast what consumers want based on their online behaviours. Companies are also keen to leverage data and machine learning to understand the psychological aspects of consumer behaviour, which cannot be observed directly but can provide valuable insights about how to improve targeted advertising.
For example, an 'extravert consumer' might be attracted to marketing messages that match their personality, and retail brands could then choose to target such consumers by using more extraverted and creative language to advertise their products.
However, personality prediction tools available today that are used by marketing firms are not entirely accurate due to a lack of theoretically sound designs.
Principal investigator of the study, Associate Professor Lin Qiu from the Psychology programme at the NTU School of Social Sciences said, "Current machine learning algorithms for personality prediction can seem like a black box -- there are many linguistic indicators that can be included in their design, but many of them are dependent on the type of computer application used. "
"This may lead to biases and overfitting, an error affecting the performance of the machine learning algorithms. This begs the question -- how should we create robust and accurate personality predictions?"
The study found a correlation between extraverts and their tendency to use certain categories of words. The results showed a small strength of the relationship between extraversion and the use of "positive emotion words" and "social process words."
Positive emotion words are defined by psychologists -- using text analysis tools -- as words that describe a pleasant emotional state, such as 'love', 'happy', or 'blessed', or that indicate positivity or optimism, such as 'beautiful' or 'nice'. Social process words include words containing personal pronouns except 'I', and words showing social intentions, such as 'meet', 'share' and 'talk'.
"This is the first time a relationship has been established between extraverts and their tendency to use the two categories of words. As it is a small correlation, we believe that stronger linguistic indicators are needed to improve machine learning approaches, amid rising interest in such tools in consumer marketing," Assoc Prof Qiu said.
The NTU team said the findings, which was published in the Journal of Research in Personality in December 2020, can provide marketers with well-founded linguistic predictors for the design of machine learning algorithms, improving the performance of software tools for personality prediction.
How the study was conducted
Previous individual studies reviewed by the NTU team have shown that extraversion, or the general tendency to experience positive emotions and enjoy social interactions, is related to the use of words described by psychologists as "positive emotion" or "social process" words. But the strength of this reported relationship has varied substantially between the different studies exploring it.
To establish the effectiveness of such linguistic predictors, the NTU team reviewed 37 studies looking at the same topic to conduct a meta-analysis. Extraversion was determined using internationally recognised personality type questionnaires.
Moving forward, the NTU research team will investigate the relationship between extraversion and other word categories.
While machine learning and predictive analytics can provide companies and marketers with an added advantage in their business strategies, more thought must be put into the design of such analytical models, the NTU research team said.
They hope their work will provide clarity on the types of words that can help guide the development of more accurate machine learning tools for personality prediction. (ANI)

Mont-Laurier – Investments in the forestry sector spur innovation, economic growth and job creation for our citizens. That is why the governments of Canada and Quebec are providing financial assistance totalling $8.4 million to Uniboard Canada Inc. The company, which has five plants in Quebec, operates the province's only medium- and high-density fibreboard plant, located in Mont-Laurier. The investment project, valued at more than $17 million, will enable the Mont-Laurier facilities to develop a system that will recover heat, currently dissipated into the atmosphere, and redirect it to the fibre drying system. This new process will significantly reduce the company's CO2 emissions and increase the plant's production capacity, thereby improving competitiveness with foreign manufacturers. About 100 jobs will also be saved as a result of the project.

Films We Can't Wait to See in 2017
: Life News
: 2020-02-03T07:19:22Z Tuesday, 27 Dec 2016 - 11:19 PM
If we're going to be honest 2016 hasn't been a great year for cinema. Sure there have been some brilliant films released (Have you seen Rogue One: A Star Wars Story!) but the majority have left audiences feeling disappointed.
Warer Bros and DC Comics fell flat on their faces as it launched its attempt at a cinematic empire, X-Men: Apocalypse was just a terrible mess and even Zoolander 2had zero personality.
However, 2017 is now on our doorsteps and looks set to be a fantastic year for film. There are returns from some much loved characters, plenty of sequels to get excited about and much, much more to look forward to.
Here's a quick list of everything we're excited about…
Martin Scorsese is one of Hollywood's greatest directors and his next film Silenceis already being applauded as one of his best works. It's taken 28 years for the film to reach our screens so it better be good!
Released January 1.
Dream team Ryan Gosling and Emma Stone reunite for this modern day musical set in the city of stars and dreams.
Released January 13.
T2: Trainspotting
Director Danny Boyle has brought the whole gang back twenty years later for a sequel that the world's been waiting for.
It's safe to say that the Fifty Shades series is not for everyone but there's undoubtedly a fan base out there that can't wait for the sequel which looks sexier, thrilling and ultimately a whole lot darker.
Released February 10.
If the adventures of bottom slapping Christian Grey don't appeal to you, there is an alternative film to see in February. Will Arnett's Batman was the best thing about The Lego Movie and now he has his very own film.
The first of many superhero films we can't wait to see is Logan. Hugh Jackman just never fails to please as Wolverine.
Released March 3.
Guardians of the Galaxy: Vol 2
The first film surprised audiences with its quick wit, funky soundtrack and offbeat humour and the sequel looks set to be bigger and better, especially thanks to the adorable Baby Groot.
Released April 28.
Alien: Covenant
Yes Prometheus was a mess but Covenant promises more action, Xenomorphs and less bullshit.
Released May 19.
Gal Gadot's Wonder Woman was the only decent thing about Batman V Supermanand let's face it; it is about time we had a female led superhero movie.
Released June 2.
Now, it is about time we had a decent Spider-Man film and here's hoping this is it.
Released July 7.
Movie maestro Christopher Nolan has made a war film. What more could you want?
Released July 21.
Many fans were feeling rather anxious about this sequel however after director Denis Villeneuve's Arrival stunned us we now know it is in safe hands.
Released October 6.
2016 was a crap year for DC Comics after both its films disappointed but the footage from their version of The Avengers looks incredible.
Released November 17.
Star Wars: Episode VIII
It's Star Wars!!!!! That is all.
Released December 15.

How Apple is selling its "Planet of the Apps" show
Kia Kokalitcheva
Apple VP Eddy Cue offered insight at Recode's Code Media conference on Monday into the company's upcoming exclusive show, "Planet of the Apps:" It's about culture.
The show: The premise is simple. Vetted app makers have 60 seconds to pitch their app idea to the show's star judges—Will.i.am, Gwyneth Paltrow, Gary Vaynerchuck, and Jessica Alba—for the chance of getting one of them as a coach. In the end of weeks of mentoring, those select few will present in front of partners from Lightspeed Venture Partners (Snapchat's earliest VC investor). It's like "Shark Tank" for the app world.
"Rubber banding:" Because the show will be available via Apple Music's app, this means viewers will be able to pause an episode and look through content about one of the entrepreneurs, an app, or one of the investors. Viewers can stretch into one aspect of the episode, then get right back to watching what happens—like a rubber band.
Culture: In the end, Cue argues that the show, like the rest of Apple Music, is about culture. Music is just one component of culture. MTV, for example, which got its start as a music video channel, hasn't always produced only shows about music.
What about Netflix? Asked why Apple wants to make its own shows instead of buying content makers like, say, Netflix, Cue said his company can produce unique content and doesn't need to go that route.


Last year during the local Terroir Creative Writing Festival I found that there were four of us in our rural proximity that shared a love of writing and poetry. We are all novices on a path to discovery. Why not get together now and again?
Last October we did just that. The first meeting took place on a Sunday afternoon at Patricia's lovely greenhouse. We sat at a table nibbling a delicious homemade coffee cake and sipping tea while a tangle of tomatoes and other vegetables seemingly were our audience. Then we rotated to Linda's, my farmhouse and next month it is Deb's turn.
A sort of agenda has emerged. The person hosting leads off with something they've read that they would like to share and then some of their personal writing. I am working on a memoir piece. The last two meetings I have read parts of it. We discuss and offer feedback on pieces if requested and then take turns. We all adore Mary Oliver. At her recent passing, there has been much to share.
At our last meeting, we suggested all purchasing Oliver's book "A Poetry Handbook" as a resource that we all have in common. For writing challenge we have suggested finding a poem we like, using it as a "pattern" and then writing a new poem with our own words to share. With all of our so-called assignments we put in the qualifier "or not." There is no pressure here, just pleasure.
Since I have a penchant for naming things, the name "The Nuthatch Society" came into my mind for our group. The four of us live on rural property and we are quite familiar with these quirky little birds that frequent the foliage and feeders about our homes. They are busy creatures, quite chatty, cute, but fierce and have the ability to walk upside down on trees. The name seemed to fit with us.
There is value in online community but it cannot compare with four souls coming together to share a common interest over tea. I'm so looking forward to the next meeting of the Nuthatch Society and sharing my writing and all the fascinating things I've read this month as well as what my fellow Nuthatches have been up to in their busy lives. Community is a powerful thing- no matter how small.
Your group sounds delightful, Alanna. There is nothing like have a group of artists to share art with. Thanks for sharing with us all about this lovely group.


Alphamax is going to release the very cute 1/7th scale figure rendition of Yozora Mikazuki from the Japanese light novel Boku wa Tomodachi ga Sukunai. Figure slated for a November 2012 release and will retail for around ¥6,800. Unfortunately, as with previous Alphamax figure releases, this figure is not cast off enabled.

Math teacher arrested at JFK airport
By Accord
September 27, 2006 in Off-Topic
NEW YORK, NY - A public school teacher was arrested today at John F. Kennedy International Airport as he attempted to board a flight while in possession of a ruler, a protractor, a set square, a slide rule and a calculator.
At a morning press conference, Attorney General Alberto Gonzales said he believes the man is a member of the notorious Al-gebra movement. He did not identify the man, who has been charged by the FBI with carrying weapons of math instruction.
"Al-gebra is a problem for us," Gonzales said. "They desire solutions by means and extremes, and sometimes go off on tangents in a search of absolute value. They use secret code names like 'x' and 'y' and refer to themselves as 'unknowns', but we have determined they belong to a common denominator of the axis of medieval evil with coordinates in every quadrant. As the Greek philanderer Isosceles used to say, 'There are three sides to every triangle'."
When asked to comment on the arrest, President Bush said, "If God had wanted us to have better weapons of math instruction, He would have given us more fingers and toes." White House aides told reporters they could not recall a more intelligent or profound statement by the president.
:mischief
Damnit, why'd this have to be moved to the Locker Room? It was funnier in the BullPen when you were expecting a real thread :thumbup .

I use to play the game all the time but I eventually unistalled it. Then, when I tried to re-install it some time later, it gives me the ''nvidia(tm) is not up to date'' error. I tried ignoring it but when I get to the game setup and press ''play'', the game simply won't launch. I don't even get a message, it just doesnt start.
Maybe I deleted something I shouldnt have when I made some space by clearing useless stuff on my computer.
Try manually installing the latest physx drivers from nvidia?
I'd get the latest forceware drivers, should include physx. what kind of graphics set up do you have? is it a laptop?
I no longer have this error, but the first one reappeared agaihn.... This is getting frustrating.
