Hector Rodriguez: Year in Review: Understanding Fraud Trends During COVID-19
Posted: 1 year ago
Hector Rodriguez, Senior Vice President &
Regional Risk Officer, CEMEA, Visa
Consumers have fully embraced digital payments in the COVID-19 era. In fact, a staggering 78% of consumers have now completely adapted their payment methods due to safety concerns and 48% will no longer shop at a store which doesn't offer contactless payment.[1] While presenting enormous opportunity for digital-first retailers, these new behaviors are not without risks.
With consumer's shift online, fraudsters have sought opportunities to exploit changes in how people pay for goods and services. Global businesses reported an average of 4,000 cyberattacks on average per day since COVID-19, representing a 400% increase from what was reported pre-pandemic[2]. In turn, we were seeing organizations adopting new security procedures to ensure transactions remain trusted and secure.
COVID-19 presents fraudster with new opportunities
This new era of fraud is marked by more sophisticated attempts to trick people into sharing sensitive information. For example, across Central Europe, Middle East and Africa, we have seen an increase in social engineering attacks, including phishing, where fraudsters are exploiting the gaps which existed pre-pandemic and have intensified during the crisis. Phishing, specifically, has grown much more complex throughout the pandemic, and now includes a number of variants, such as spear phishing - attacks targeting a specific victim with personalized communication and vishing (voice phishing scams), as well as spoofed websites.
Impersonations can be made to appear like family, friends, executives, or government officials.
'Friendly fraud' is another type of attack on the rise, where individuals' card and passcodes are used without permission by friends, family or other close associates. For merchants it can be a cost of doing business because it's difficult to track, and most of time refunds are issued without investigating the matter further. Friendly fraud is said to reduce legitimate sales by 1% and profits by 20%[3].
Ecosystem responded well
Despite this, the commerce ecosystem has recognized the challenges and responded well, taking a technology-led approach to address emerging threats. While most businesses were already investing in technology-led security systems, the pandemic kicked this into overdrive, as businesses fought to better combat fraudsters and navigate the new, digital world. As businesses accelerated the use of secure technologies, including tokenization, contactless and EMV 'smart card' chips, the secure nature and performance of digital transactions also improved.
Investing in security for the post-COVID world
With COVID-driven uncertainty set to remain in the near future, the next 12 to 18 months may bring even more disruption and transformation. However, I believe that the dramatic shift we have seen towards digital payment will continue as consumers and merchants show increasing preference for eCommerce and contactless payments.
The pandemic has undoubtedly accelerated the widespread use of digital payment methods, with customers across the globe opting for contactless payment and digital alternatives. Even as lockdowns lift, the growth in digital commerce continues, indicating a real shift in consumer behavior and one which will last well into the new year, and long after COVID-19. In fact, 96% of consumers in the CEMEA region expect that their use of e-commerce will increase or stay the same post COVID-19.[4]
Given how rapidly consumer behavior is changing and how sophisticated fraudsters are, it is not surprising that the complexity of risk management will likely increase in the near future. 79% of organizations say that risk management will be a growing focus for their company over the next two years[5].
As we move forward, merchants are expecting contactless usage to grow by around 30% post pandemic, making it more important than ever for organizations to embrace the demand for digital.[6] Of course, as fraudsters become increasingly sophisticated in a digital world, organizations must innovate and invest in technology to, not only meet evolving demands, but to ensure the safety and security of digital transactions for customers. Investing in new, innovative ways of onboarding customers and new ways to pay, such as online, in-app, contactless, and IoT, will make or break a business in a post-COVID-19 world.

Massa tops the times for WilliamsCredit: Pirelli S.p.A.
It was a quiet day of pre-season testing in Spain as the final week began under blue skies in Barcelona. Teams looked to be running longer distances than they did in the first four days, and were concentrating on getting a complete package out of their car, moving on from the early shakedowns we saw last week. There was just one red flag today, brought out by Renault right at the very end of the session.
Pascal Wehrlein finally got his Sauber career going, making an appearance in the car in the morning. He completed a handful of installation laps before finally getting a timed lap on the board more than two hours later. He handed over to Marcus Ericsson for the afternoon session, with Mercedes and Renault also running a two-driver strategy.
It was bad news for Renault on the engine front, as they had to change the car's main component. McLaren were also spotted undergoing a change of engines, as Stoffel Vandoorne stood by watching on. However, all attention was on Felipe Massa, who showed what can be done by posting the most number of laps and going fastest overall.
I don't think we are in the same level as Mercedes but I think if we can fight and having a great fight, maybe fighting for podiums already, definitely a great job. But we need to wait and see in Australia.
Ferrari also managed to equal Massa's tally of laps with a whopping 168 each for Felipe and Sebastian Vettel. Although Ferrari have been setting the pace so far this pre-season, they finished behind both Williams and Red Bull in the timesheets. The top three were the only ones this Tuesday to finish under 1:20.
Teams having a quiet day included Mercedes, who just allowed their two drivers to get on with proceedings - Hamilton handing over to Bottas halfway through the day. Toro Rosso also kept their heads down, with Daniil Kvyat setting a pretty average 83 laps and finishing ninth in the standings.
Marko: "We do see our chance this year: the simple design of our car, the driveability of the car, our drivers & the stability in the team"
With three more days on the schedule, teams are keen to get as much running in as possible. We've got Mercedes and Renault running both their drivers tomorrow, whilst Williams are fielding Lance Stroll and no doubt keeping their fingers crossed that he brings it home in one piece. All the other teams are swapping their drivers from today, with Räikkönen, Alonso, Pérez and more set to make their first appearance of the week.

Grapevines and their clusters are very rich in components with different and interesting healthy effects, which also extend to grape derivatives such as must, wines and all other products (extracts, flour, leaves, seeds, pomace, etc.). Bioactive constituents present in grapes and vines, mainly polyphenols, are attracting increasing interest from consumers demanding polyphenol-rich foods as a result of epidemiological evidence suggesting the protective potential of polyphenols against chronic diseases directly associated with oxidative damage, such as Alzheimer's, cancers, diabetes, and hypertension, amongst others. In this regard, besides the traditional products from grapes, such as wine and juice, grape Vitis by-products are increasingly being re-utilized and transformed into high-value products for the food, cosmetics, and pharmaceutical industries. In this context, this book deeply discusses many aspects of the products derived from grapevines, including the diversity and potential of a wide range of economical possibilities, factors involved in their composition, varietal differences, and industrial process, showing a wide range of possibilities.

Greenville's Downtown Rotary Club is celebrating its centennial in style
Judith Bainbridge
Greenville's Downtown Rotary Club is celebrating its centennial in style.
The Upstate History Museum had a major display and the South Carolina Room of the Hughes Library showcased old photographs.
A hundred years of fellowship (emphasis on the "fellows" for the first 70 years) and good works are certainly worth commemorating.
In January 1933, club directors considered writing a brief history, but no one volunteered, so none was written. These "Early Rotary Days" will attempt to show the camaraderie and the commitment to Greenville that has characterized the organization since its beginning.
January 7, 1916: The Rotary Club of Greenville organizes this Friday evening with 25 "live-wire" leaders at an elaborate dinner-meeting at the Ottaray Hotel. J.E. Sirrine is elected president.
May 4, 1916: The Club entertains Allen D. Albert of Minneapolis, President of the International Association of Rotary Clubs. Delegations from Atlanta, Augusta, Asheville, and Spartanburg attend a gigantic Main Street parade marking the start of Greenville's "Great White Way" (a dozen neon signs electrifying Main Street).
May 22, 1917: Rotarians are the first to learn that Greenville has been chosen for a huge military "cantonment," Camp Sevier.
December 25, 1917: The Greenville News and the Rotary Club co-sponsor a gigantic Christmas party at Textile Hall for 20,000 soldiers stationed at Camp Sevier.
May 27, 1919: The Club's luncheon guest is Southern Baptist Theological Seminary Professor W. J. McGlothlin, to whom Furman University had just offered the position of president. Dr. McGlothlin announces he will accept the presidency if Furman builds a gymnasium. Rotarians "promptly assume the obligation." Dr. McGlothlin becomes president.
October 25, 1919: Many Rotarians attend the dedication of Furman's Manly Field. Raising funds for its construction was the Club's second major project (the first was building Textile Hall).
March 15-16, 1920: Greenville hosts 650 delegates to the Rotary District Conference (including the Carolinas and Virginia).
August 17, 1920: The Club agrees to spend $10,000 over the next three years on programs for boys. Roger Huntington addresses the Rotary International Convention about Greenville's Boys Work program.
September 6, 1921: The Rotary Club's guest is Brigadier-General Smedley D. Butler, Commandant of Marines at Quantico, Virginia. "Hell Devil" Butler, a "fighting leatherneck" for 23 years, "proves to be a quiet and charming guest."
March 29, 1922: Furman breaks ground on a new gymnasium. Rotarians raised $60,000 of the $80,000 needed to build it.
July 25, 1922: Members marvel at "a demonstration in transmission of the human voice, music, and other sounds through the air without use of wires." Greenville radio pioneers Roger Huntington and Dupont Guerry broadcast music to the Rotary Club meeting at the Imperial Hotel from their studio on River Street.
August 23, 1922: Members are guests at a supper held in a cow barn. Dairyman King Thackston, a Rotarian, hosts a meal made entirely of products of his farm.
December 30, 1922: The Saluda Land and Lumber Company donates 400 acres near Cedar Mountain to Greenville's Central Y.M.C.A. for use as a boy's summer camp. Rotarians pledge $5,500 of the $7,000 needed to build the camp.
February 22, 1924: A "delightful" Ladies Night at the Christ Church Parish House focuses around a radio address by President Calvin Coolidge.
April 5, 1927: Members discuss extending the city limits to two and a half miles from the courthouse. (Two weeks later, Greenville's voters reject the proposal by a vote of 569 to 410.)
September 10, 1925: The faculties of Furman University and Greenville Woman's College are special guests.
October 6, 1925: The meeting features an old-fashioned spelling bee conducted by Parker Schools Superintendent Pete Hollis. The prize, a fountain pen, is won by Dr. J.L. Mann, superintendent of city schools.
November 17, 1926: A president of Rotary International visits the Greenville Rotary Club for the third time. During his address at the Poinsett Club, he urges the Greenville Club to consider adopting a weekly meeting schedule like almost every other club in the nation.
November 30, 1926: The Club debates the question of weekly meetings. A secret balloting of the membership shows 29 in favor of weekly meetings and 44 opposed. (The Downtown Club still meets biweekly.)
May 4, 1927: Greenville's Rotary Club celebrates International Boys Week. Boys hold all the positions in the city government for the day. That afternoon, the Rotary Boys Band leads a parade from Main Street to Graham Baseball Field on Augusta Street, where they are guests of Greenville Spinners' Manager Frank Walker.
October 30, 1928: Every club meeting includes group singing led by Song Leader Pete Hollis. Today, however, he is stumped when a member suggests that they sing "The Sidewalks of New York" in honor of the presidential race between Al Smith and Herbert Hoover. Neither Hollis nor Wilton Earle, an ardent Smith supporter, can remember the words.
March 5, 1929: The Club passes a resolution "authorizing payment of membership dues by post-dated checks." Members also pledge $1,500 to the Boys Work program.
May 22, 1929: A dinner meeting at the Poinsett Hotel honors seventy Rotarians and their wives from six foreign countries who are en route to the Rotary International Convention in Dallas. "Fine fellowship and good will abounded."
July 11, 1930: The club moves its regular meeting to Friday for a joint meeting with other civic clubs honoring the Greenville County 4-H Club, whose members have won prizes in state-wide contests.
September 16, 1930: The first air mail flight lands in Greenville. Guests of honor at Rotary are Frank G. Hamblen and Alester G. Furman, Sr. who were instrumental in building Greenville's airport.
October 10, 1931: Members meet at the new Shriners Hospital for Crippled Children after visiting the Hopewell Tuberculosis Sanitarium. The children at the Shriners Hospital provide an "interesting and appealing" program, and the Rotarians pay for a "bountiful dinner."
December 6, 1932: The club rejects a proposal that Furman's football team be their special guests, "due to existing financial conditions."
November 11, 1933: The program features an Armistice Day program. The 27 Rotarians who had served in World War I were asked to attend in uniform. "Sandbags, barbed wire entanglements and other reminders of the battlefield formed a realistic setting for the program."
Hundreds of "Rotary Days" later, the oldest club in the state and founder of a dozen others, members of the Greenville Downtown Club still help support Greenville's sense of community.

April 2003-2004: Suspected Iraqi Insurgents Interrogated at Delta Force Facility with Poor Reputation
Captured suspected "insurgents" and other militants are brought to the ultra-secret Battlefield Interrogation Facilities (BIF) in Baghdad run by Delta Force. NBC will report that "it is the scene of the most egregious violations of the Geneva Conventions in all of Iraq's prisons." BIF is described as a "place where the normal rules of interrogation don't apply." Prisoners "are kept in tiny dark cells. And in the BIF's six interrogation rooms, Delta Force soldiers routinely drug prisoners, hold a prisoner under water until he thinks he's drowning, or smother them almost to suffocation." Pentagon officials will deny that prisoners held at the facility are subjected to illegal interrogation tactics. [MSNBC, 5/20/2004; CNN, 5/21/2004 Sources: Two unnamed top US government sources]
July 15, 2003: 519th Military Intelligence Battalion Produces Memo on New Interrogation Rules
The 519th Military Intelligence Battalion produces a memo laying down new "Interrogation Rules of Engagement" (IROE), for use in its new mission in Iraq. [US Department of the Army, 3/9/2004] The person apparently mostly responsible for writing the memo is Cpt. Carolyn A. Wood, formerly in charge of military intelligence interrogators at Bagram, which serves as the main screening area in Afghanistan. [Guardian, 6/23/2004] Col. Billy Buckner, the chief public affairs officer at Fort Bragg, home to the 519th Military Intelligence Battalion, later says that Wood brought the interrogations rules used at Bagram with her to Iraq. [Associated Press, 5/24/2004] But the rules are also adapted and made somewhat less aggressive. "Those rules were modified," according to Buckner, "to make sure the right restraints were in place." [Guardian, 6/23/2004] The modifications nevertheless fall outside normal military doctrine. According to a classified portion of the later Fay report (see August 25, 2004), the memo allows the "use of stress positions during fear-up harsh interrogation approaches, as well as presence of military working dogs, yelling, loud music,… light control," sleep management, and isolation. [New York Review of Books, 10/7/2004] The memo is adopted from interrogation procedures known as "Battlefield Interrogation Team and Facility Policy," in use by a secretive unit called Joint Task Force (JTF) 121 , that is active in both Iraq and Afghanistan. The 519th Military Intelligence Battalion worked in close cooperation with Special Operations Forces like JTF-121 during its tour in Afghanistan, and "at some point," according to the Fay report, it "came to possess the JTF-121 interrogation policy." [New York Times, 8/27/2004] Cpt. Wood adopts the JTF-121 policy "almost verbatim." [New York Times, 8/27/2004] Like the highest US command in Iraq, the 519th Military Intelligence Battalion apparently believes the standard Army Field Manual is an insufficient guideline for interrogations. Interrogation techniques falling outside the scope of standard military doctrine have already been devised at the Pentagon, but only for use in Afghanistan and Guantanamo Bay. These "non-doctrinal approaches, techniques, and practices," according to Gen. George R. Fay, nevertheless, become "confused at Abu Ghraib." [US Department of the Army, 3/9/2004] JTF-121 consists of CIA officials and Special Operations troops, including soldiers from the Army's Delta Force and Navy Seals. The unit is later alleged to have been instrumental in the capture of Saddam Hussein. [New York Times, 5/17/2004]

June 24-25, 2005: Selected Military Analysts Tour Guantanamo, Repeat Pentagon Talking Points in Media
CNN analyst Donald Shepperd. [Source: New York Times]With criticism of the Guantanamo Bay detention facility reaching new heights, new allegations of abuse from UN human rights experts, Amnesty International receiving plenty of media exposure for calling the facility "the gulag of our times" (see May 25, 2005), and many calling for the facility's immediate closure, the Pentagon counters by launching the latest in its propaganda counteroffensive designed to offset and blunt such criticism (see April 20, 2008). The Pentagon and White House's communications experts place a select group of around ten retired military officers, all who regularly appear on network and cable news broadcasts as "independent military analysts," on a jet usually used by Vice President Dick Cheney, and fly them to Cuba for a carefully orchestrated tour of the facility. [New York Times, 4/20/2008]
A Four-Hour Tour - During the three-hour flight from Andrews Air Force Base to Cuba, the analysts are given several briefings by various Pentagon officials. After landing, but before being taken to the detention facility, they are given another 90-minute briefing. The analysts spend 50 minutes lunching with some of the soldiers on base, then begin their tour. They spend less than 90 minutes viewing the main part of the Guantanamo facility, Camp Delta; in that time, they watch an interrogation, look at an unoccupied cellblock, and visit the camp hospital. They spend ten minutes at Camp V and 35 minutes at Camp X-Ray. After less than four hours in Guantanamo's detention facilities, they depart for Washington, DC. [Salon, 5/9/2008] This is the first of six such excursions, all designed to prepare the analysts for defending the administration's point of view and counter the perception that Guantanamo is a haven for abusive treatment of prisoners. During the flight to the facility, during the tour, and during the return flight, Pentagon officials hammer home the message they want the analysts to spread: how much money has been spent on improving the facility, how much abuse the guards have endured, and the extensive rights and privileges granted to the detainees.
Producing Results - The analysts provide the desired results. All ten immediately appear on television and radio broadcasts, denouncing Amnesty International, challenging calls to close the facility, and assuring listeners that the detainees are being treated humanely. Donald Shepperd, a retired Air Force general, tells CNN just hours after returning from Guantanamo, "The impressions that you're getting from the media and from the various pronouncements being made by people who have not been here in my opinion are totally false." The next morning, retired Army General Montgomery Meigs appears on NBC's flagship morning show, Today, and says: "There's been over $100 million of new construction [at Guantanamo]. The place is very professionally run." Transcripts of the analysts' appearances are quickly circulated among senior White House and Pentagon officials, and cited as evidence that the Bush administration is winning the battle for public opinion.

The Cinematic Feels & Emotional Stability of Snoh Aalegra
Following the release of her acclaimed new album, Snoh has taken her talents on tour.
Samantha O'Connor01 Nov, 2017
Head or heart - Which takes precedence?
It's really the absurdly archaic question. One that's never received a unified answer. Follow your head and you could end up miserable. Follow your heart and you could end up fucked.
Snoh Aalegra knows the consequences. The Stockholm-born, L.A.-based artist has had plenty of life experience toying with the question. She writes about her ultimate outcomes in the emotion driven songs that are penned directly from her own timeline, like the soaring R&B numbers on her latest album FEELS. And she studies the juxtaposition of both results in the art she chooses as inspiration. Like favourite film, Vicky Cristina Barcelona - a visual reminder that the blend of head and heart doesn't always create an equilibrium.
But as long as Snoh keeps feeling, she'll keep writing. And that comes first.
The way I was just ringing down your phone, I was scared you were going to think I was a crazy ex-boyfriend.
Oh, I'm definitely used to that. Just joking.
You're currently on tour with Daniel Caesar. How has that experience been so far?
Amazing, his fans are crazy in a good way. It's been a blessing to perform even though we've only done five shows. We have so many to go. But every night has been magical, I'm not even exaggerating. It's been so much fun.
I'm from Toronto, Daniel's hometown. So it's safe to say the city is looking forward to your five back-to-back show run. You might just have to move here.
Yeah. I'm going to come there a week ahead actually to work with some of the producers over there. And it's my first time coming to Toronto, so I'm looking forward to it. The ones I've been talking to about working together are T-Minus and Boi1da.
You've worked with 1da before obviously, which is how Drake's 'Do Not Disturb' came to be.
Yes yes yes. We did that and we also did a song called 'Charleville 9200' on my previous project.
Congrats on FEELS by the way. Obviously you went from working on the project to putting it out and then jumping straight into the tour. So, how has your year been and is it what you expected from all your hard work?
I've been working on the album for almost two years, since the previous project. Things took a little bit longer than expected. I had a lot of voice problems at the beginning of the year and I kind of lost my voice for a few months. So that delayed the album and finishing it up. But everything is running smoothly now and this tour was a blessing. It just sort of came up and they asked me if I wanted to do it and it was dope timing with the album coming out and I just get to meet new people every day at these shows and meet new fans. It's been really dope. I'm just on the road now and I've been in the studio, so I'm very much in these environments so I don't notice much change. But I notice more growth and I feel like more people are discovering the music, so I love that.
The album is such a sensory experience based on the emotional power behind the songs. How was the process of preparing to deliver those authentic feels in a live experience on tour?
Right now, on this tour, since I'm an opener, I have a shorter set. So I'm singing a few songs from this album and a few from Don't Explain. I can say that definitely, every time I perform the song 'Time,' I get super emotional. It's kind of hard, because I'm a person that really gets into it and into the song while I'm performing it. And for me, that's nothing that I can really do to prepare for that. I just go with the flow.
When it came time to record, what was our process of tapping into those places and emotions in a more isolated space?
I actually never record in the booth. I sit in the control room with a hand mic. I don't use those extensive microphones. I just don't like the sound of them so much. They're too clear and crispy for me. Sometimes, it's nice but I actually didn't use it at all on my project. The same mic that I use on stage is the same one that I record my songs on in the studio. All songs have different emotions, obviously. And all my songs are super personal. So, I really dig into all these emotions and it can be really draining after a night in the studio. I come home and my brain is on a loop and it takes me some time to chill out and be able to fall asleep. I'm repeating all these emotions over and over. Doing different takes. Tapping into the exact feeling of how you felt. It's a challenge.
You're admittedly a very emotion driven person and you've said before that you usually feel before you think. But as an artist, how do you describe what emotional stability is to you?
I'm definitely not a person to ask advice from, because I don't have emotional stability. I'm all over the place. That's why I'm a writer. I do really feel before I think, which is really good when you write songs. It's not the best advice to take when you're making life decisions. Sometimes you need to think with your head and not with your heart. I have a lot of people around me giving me good advice that I should be following but I just don't. I'm the type of person that needs to get burned from my own experiences and learn the hard way before I learn the lesson. That's who I am.
But you make great songs out of those experiences so it's not a loss.
Yes, at least something good comes out of it.
What are you most proud of when it comes to your album FEELS in terms of what you produced as the artist you see yourself as?
I'm just very happy that I didn't have to compromise anything. I just got to do a project that I love. I have such a great team that lets me do whatever I want and they help me figure everything out. We sit and listen to the songs when they're done and we go through them together. We do a little test where we mute the production sometimes and leave one instrument in there just to see if it's a real song that you can play on just the guitar or piano. That's kind of how I test stuff. But other than that, I'm just proud and happy that I work with such amazing people and musicians. I'm super proud of my band that I have with me on tour. They're just incredible. I'm most proud that I get to stand next to these people and perform.
A word that gets used a lot when it comes to your work is "cinematic." If you could have one actress or one director play out your narrative through film, who would it be?
I do really love Penelope Cruz. I'm obsessed with her and her husband Javier Bardem. One of my favourite films is Vicky Cristina Barcelona. If I could have that cast, that would be awesome. And Martin Scorsese can direct it.

Chelsea and Arsenal offered two options to sign Barcelona star Philippe Coutinho
04/14/2020 Comments Off on Chelsea and Arsenal offered two options to sign Barcelona star Philippe Coutinho
Barcelona are reportedly desperate to offload Philippe Coutinho this summer they have offered Chelsea and Arsenal two options to wrap up a deal.
Coutinho has struggled to find his top form since moving to the Nou Camp from Liverpool for £142million in January 2018.
The Brazilian has spent this season on loan at German giants Bayern Munich but his performances have been below par.
The Bundesliga side are not keen on making the move permanent so Barcelona will have to find new suitors.
According to the Sun, Premier League duo Chelsea and Arsenal will be given two options.
They claim the first is a 12-month loan in which half of Coutinho's £290,000-a-week wages would need to be covered.
The second option is a cut-price permanent transfer for a £75m fee.
Manchester City are also said to be interested but Arsenal and Chelsea are more likely to land the 27-year-old.
It is unclear if Coutinho will ever be able to rediscover his top form so paying for a long-term deal is much more of a gamble.
Despite this, former Liverpool star Phil Thompson reckons Jurgen Klopp should join the race to take the midfielder back to Anfield.
Man Utd have Premier League title issue if they sign Harry Kane
"They are probably looking at that creative midfield player," he said.
"Would you take Coutinho back? I would, in a heartbeat. I think he's a creative genius.
"You look back at his Liverpool career and he was absolutely terrific.
"He's not too old and I still think he could come back.
"It probably won't happen but it's that creative player just off the front three that would probably just tip the balance."
Coutinho's agent Kia Joorabchian has explained that his client would "love" a return to England.
"The fact I'm an Arsenal supporter is not a secret," he told Sky Sports News. "I don't have any preference where the players go.
"I don't try to push someone to one club or another. Everything is a possibility.
"After the Champions League game he played in England we had a long chat about it. The Premier League is something that he has always enjoyed playing in, and loved playing in, and would probably love to come back and play in."

\section{Introduction}

Coulomb disorder plays dominant role in determining thermodynamic and kinetic properties of doped semiconductors due to its long-range nature.~\cite{SE-Book} This physics becomes especially intriguing in the context of Dirac materials, namely solid state systems that host quasiparticles with linear dispersion near the band-touching degeneracy points, such as that in $d$-wave superconductors, \cite{BalatskyReview} graphene, \cite{Graphene-Review-1,Graphene-Review-2} topological insulators \cite{TI-Review-1,TI-Review-2} and Weyl semimetals. \cite{Turner2013,Vafek,Burkov-Review} While the former three classes of systems have been intensively studied over almost a decade by now, materials that can be identified as Weyl semimetals have been discovered only fairly recently. \cite{Kim2013,WSM-Exp-1,WSM-Exp-2,WSM-Exp-3,WSM-Exp-4,WSM-Exp-5,WSM-Exp-6,WSM-Exp-7,WSM-Exp-8}

Theoretical studies of the effect of disorder on a single Weyl node have a long history, \cite{Fradkin} and this problem has been revisited in a number of recent works. \cite{Herbut, Ominato-1,Sbierski,Syzranov-1,Skinner,Altland} The prevailing point of view is that a weak disorder has negligible effect on the density of states, which vanishes quadraticaly with the energy counted from the nodal point. This behavior persists up to a certain critical disorder strength beyond which the density of states acquires a finite value at zero energy. Obviously, such scenario should have serious implications for the transport properties of WSMs that rely on their semimetallic nature (a vanishing density of states at the nodal points). \cite{Burkov-Hook,Hosur,Ominato-2,Syzranov-2,Rodionov-1,Rodionov-2} At strong disorder singular transport features are eliminated. It is thus important to have a controlled theory of disorder effects on a single nodal point. Conventional treatments based on the self-consistent Born approximation, though can be qualitatively correct, are uncontrolled near Dirac or Weyl points. \cite{Sbierski}

Magnetotransport properties of WSMs are also expected to have a highly unusual character owing to the unconventional Landau quantization for the three-dimensional Dirac spectrum, and the multiband nature of Weyl semimetals.  In particular, a strong classical negative magnetoresistance was predicted for Weyl systems with long intravalley relaxation times, \cite{Son-Spivak,Spivak-Andreev} as well as robust linear positive magnetoresistance in the quantum limit, when a single Landau level is occupied. \cite{Abrikosov} Both types of behavior were recently observed in experiments \cite{Ong,Feng} on a candidate Dirac (``double-Weyl'') material Cd$_3$As$_2$, yet at this point it cannot be stated with confidence whether the experimental observations are in full correspondence with theoretical models. For various recent theoretical and experimental aspects of magnetotransport results in Dirac semimetals see Refs.~\onlinecite{Yang,Gorbar,Ghimire,Burkov-MR,Shen-1,Shen-2,Goswami,Adam,Klier,Shekhar}.

In light of the recent experimental advances that triggered a flood of theoretical work, our essential motivation is to investigate the role of Coulomb impurities on properties of WSMs. In contrast to the model of short-range disorder, which so far received most of theoretical attention, we obtain results that are controlled by a small parameter in the limit of \emph{strong} disorder. We also observe that due to the delicate interplay of Landau quantization and screening effects, the low-field magnetoresistance may display nonmonotonic behavior. The latter feature is highly sensitive to the strength of interaction and thus is not universal.

\section{Model of a Weyl semimetal with long-range disorder}

The quasiparticle dispersion in the vicinity of a single isotropic nodal point can be described by the effective Hamiltonian ( $\hbar=c=1$ throughout)
\begin{equation}\label{H}
H=v{\bm \sigma}\cdot \bm{p}+u(\bm{r}),
\end{equation}
where $v$ is the Fermi velocity, and ${\bm \sigma}$ and $\bm{p}$ are vector of the Pauli matrices, and momentum measured relative to the nodal point. The total potential as seen by an electron at position $\bm{r}$ due to randomly distributed charged impurities at positions $\bm{r}_i$ is taken in the form of a Yukawa-like potential
\begin{equation}\label{u}
u(\bm{r})=\sum_i\phi(\bm{r}-\bm{r}_i),\quad \phi(\bm{r})=\frac{e^2}{\epsilon r}\exp(-\kappa r).
\end{equation}
Here index $i$ labels impurities, $\epsilon$ is the dielectric constant of the host material, and $\kappa$ is the inverse screening radius. We assume that impurity positions are completely random, and calculate the correlator of the disorder potential,
\begin{eqnarray}\label{eq:fulldisorder}
\langle u(\bm{r})u(\bm{r}')\rangle=\left(\frac{4\pi e^2}{\epsilon}\right)^2\int\frac{d^3q}{(2\pi)^3}\frac{n\exp(i\bm{q}(\bm{r}-\bm{r}'))}{(q^2+\kappa^2)^2}\nonumber\\
=\frac{2\pi ne^4}{\epsilon^2\kappa}\exp(-\kappa|\bm{r}-\bm{r}'|),\label{uu}
\end{eqnarray}
where $n$ is the concentration of impurities. As follows from Eq.~(\ref{uu}), the correlation length of the disorder potential is given by the screening radius, and the magnitude of its fluctuations is given by $\langle u^2(\bm{r})\rangle\equiv w^2=2\pi ne^4/\epsilon^2\kappa$. The Gaussian approximation is sufficient to describe the disorder potential fluctuations when there are many impurities in the screening volume, $n\kappa^{-3}\gg1$. The model of a disordered Weyl semimetal described above will be used in the forthcoming calculations. The validity of the Gaussian approximation will be checked \textit{a posteriori}, by considering the screening of Coulomb impurities by electrons moving in a self-consistently screened disorder potential, see Eq.~(\ref{nuandkappa}), and the text below it. A detailed account of self-consistent screening in the present problem is given in Ref. \onlinecite{Skinner}.

\section{Density of states at the nodal point}

In what follows we consider the density of states (DoS) close to the nodal point, $\varepsilon\to0$, where $\varepsilon$ is the electron energy.

DoS at the nodal point crucially depends on the relation between the strength of disorder, and the energy scale associated with its finite correlation length, $\kappa v$. For $w\ll \kappa v$, the disorder is weak, and the Born approximation can be used, with the expected result of zero DoS at the nodal point. For strong disorder, $w\gg \kappa v$, self-consistent Born approximation predicts a finite DoS at the nodal point,\cite{Ominato-1} but the approximation itself is uncontrolled. \cite{Sbierski}

To obtain systematic results, controlled by a small parameter, for the DoS and later for transport properties, we restructure the perturbation theory for the disorder potential similarly to the way it was done for heavily doped semiconductors. \cite{SE-Book, Efros} A crucial observation is that for $w\gg\kappa v$, the landscape of the disorder potential is smooth, in the sense that the typical length scale at which it changes, $1/\kappa$, is large compared to the typical electron wavelength $\lambda\sim v/w$. (The latter estimate assumes that it is the \emph{total} energy of the electron that is close to the nodal point, thus the kinetic energy is of the order of $w$.) This implies that the electron motion is semiclassical. Therefore, one may use the Thomas-Fermi approximation (rather than the clean system) as the ``reference point'' around which a perturbative expansion is developed.

To illustrate the use of the Thomas-Fermi (TF) approximation in this case, we consider the single particle Green's function for the Hamiltonian (\ref{H}):
\begin{equation}\label{G-u}
G^{R(A)}[u(\bm{r})]=\frac{1}{\varepsilon_\pm-v\bm{\sigma}\cdot\bm{p}-u(\bm{r})},
\end{equation}
where $\varepsilon_\pm=\varepsilon\pm i0$, and $u(\bm{r})$ plays a role of the effective local chemical potential. In general, since the electron momentum is an operator, one cannot simply average the Green's function over the distribution of $u(\bm{r})$. However, in the semiclassical limit we can treat $u(\bm{r})$ as a number within TF-approximation and thus obtain
\begin{equation}\label{G}
\langle G^{R(A)}\rangle=\int du \, F[u]\frac{1}{\varepsilon_\pm-v{\bm \sigma}\cdot\bm{p}-u},
\end{equation}
where the distribution function for the local values of the disorder potential, $F[u]$, is defined according to
\begin{equation}
F[u]=\langle\delta(u-u(\bm{r}))\rangle.
\end{equation}
Taking the imaginary part of the retarded component of $\langle G\rangle$ gives the density of states,
\begin{equation}\label{eq:oldDoS}
\nu(\varepsilon)=\int du F[u]\nu_0(\varepsilon-u),
\end{equation}
where $\nu_0(\varepsilon)$ is the DoS of the clean system. In the case of a Gaussian disorder potential defined in Eq.~(\ref{uu}), one obtains
\begin{equation}\label{P}
F[u]=\frac{1}{\sqrt{2\pi}w}\exp(-u^2/2w^2).
\end{equation}
Using $\nu_0(\varepsilon)=g\int\frac{d^3p}{(2\pi)^2}\delta(\varepsilon-vp)=g\varepsilon^2/2\pi^2v^3$, with $g$ being the degeneracy of the nodal point for a given Weyl system, and performing an elementary integration, one finds
\begin{equation}\label{nu}
\nu(\varepsilon)=\frac{g}{2\pi^2v^3}(\varepsilon^2+w^2),
\end{equation}
that is, a nonzero value for $\varepsilon=0$.

In the context of doped semiconductors, the semiclassical equation for the density of states, Eq.~(\ref{eq:oldDoS}), was suggested long ago, e.g. in Refs. \onlinecite{Bonch-Bruevich,Kane,Keldysh,Efros}, and has been recently used to describe DoS and nonlinear screening in Dirac systems in Ref. \onlinecite{Skinner}

We motivated equation~(\ref{G}) on physical grounds, but it can be rigorously shown that it is exact in the $v\kappa/w\to0$ limit. One can formally send $\kappa\to0$ while keeping $w$ constant by considering $e^2\to0$, $n\to\infty$ limit with $en^{1/3}$ kept constant (see below). In this limit the disorder correlator is $\langle u(\bm{r})u(\bm{r}')\rangle\approx w^2$, and describes disorder with \emph{infinite} correlation length. The problem of finding the single-particle Green's function for such a disorder potential (the so-called ``Keldysh model'') is exactly solvable, since the impurity lines in the standard technique do not transfer momentum, thus all diagrams to a given order have the same value, Fig.~\ref{fig:diagrams}. The full resummation of the perturbation theory becomes a combinatorial problem, solving which~\cite{Sadovskii} requires determining the number of ways $n$ impurity lines can be attached to $2n+1$ bare Green's functions in the $n^{\text{th}}$ order of perturbation theory (the second order diagrams are shown in Fig.~\ref{fig:diagrams}). The results for the disorder-averaged single-particle Green's functions and the DoS are precisely the above Eqs.~(\ref{G}) and~(\ref{eq:oldDoS}).
\begin{figure}
  \centering
  \includegraphics[width=3.5in]{diagrams.pdf}
  \caption{Diagrams that correspond to the second-order disorder correction to the Green's function. For the impurity line that does not depend on spatial coordinates, $\langle u(\bm{r})u(\bm{r}')\rangle=w^2$, all the diagrams have the same value of $w^4 G_0^5$, where $G_0$ is the unperturbed Green's function.}\label{fig:diagrams}
\end{figure}

In what follows we consider the corrections to the result of Eq.~(\ref{nu}), following the treatment of Ref.~\onlinecite{Efros}.

\subsection{Improved perturbation theory for long-range disorder}

To build an improved perturbation theory for the potential defined by Eq.~(\ref{uu}), we formally rewrite the latter equation as
\begin{equation}\label{udecomposition}
  \langle u(\bm{r})u(\bm{r}')\rangle=w^2+w^2\left(\exp(-\kappa|\bm{r}-\bm{r}'|)-1\right).
\end{equation}
If the second term in the right hand side of the above equation is neglected (the corresponding condition to be formulated below), one recovers the case of an infinite-range disorder potential, which was discussed above.

Going beyond the Keldysh model, when is it appropriate to treat the second term in the right hand side of Eq.~(\ref{udecomposition}) as a small correction? It is clear that one should require that $\kappa|\bm{r}-\bm{r}'|\ll1$ for the relevant values of $|\bm{r}-\bm{r}'|$. Since the solution for the semiclassical problem is represented by an ensemble average over samples having a random, but spatially uniform chemical potential of order $w$, see Eqs.~(\ref{G}) and (\ref{P}), the relevant value of $|\bm{r}-\bm{r}'|$ is of the order of the wavelength corresponding to the energy $w$, $|\bm{r}-\bm{r}'|\sim v/w$. Hence the corrections to the semiclassical approximations are expected to be small for $\kappa v/w\ll1$, coinciding with the condition for the validity of the semiclassical approach formulated above.

Our next immediate goal is to find the leading $\sim O(v\kappa/w)$ correction to Eq.~(\ref{nu}) due to the short-range component of disorder potential. As we are going to see, it is regular and free from divergencies near the Dirac point. The full disorder-averaged Green's function can be written as~\cite{Efros}
\begin{equation}\label{Gfull}
\langle G^{R(A)}\rangle=\int du \, F[u]\frac{1}{\varepsilon_\pm-u-v{\bm \sigma}\cdot\bm{p}-\Sigma}.
\end{equation}
Here, for every value of $u$, the self-energy $\Sigma$ is determined from the usual diagram technique for disordered metals, in which the role of the bare Green's function is played by Eq.~(\ref{G-u}) with $u(\bm{r})$ replaced with $u$, and the impurity line (in momentum space), $D(\bm{q})$, is determined \emph{only} by the second term in the right hand side of Eq.~(\ref{udecomposition}):
\begin{equation}\label{impurityline}
  D(\bm{q})=\frac{8\pi w^2\kappa}{(q^2+\kappa^2)^2}-(2\pi)^3w^2\delta(\bm{q}),\quad\int d^3q D(\bm{q})=0.
\end{equation}
In Eq.~(\ref{impurityline}) $\delta(x)$ is the Dirac delta-function. Its appearance signals that the long-range part of the impurity potential is subtracted from $D(\bm{q})$, as it has been already treated exactly by the averaging over the values of $u$. We will see below that after such removal, a simple Born approximation is valid for the short-range part of the disorder potential if $\kappa v\ll w$.

Nonetheless, below we set up the self-consistent Born approximation (SCBA) for the self-energy for the modified disorder correlator, Eq.~(\ref{impurityline}). We will not go beyond the first Born approximation in actual calculations, but having the full SCBA set up will allow us to contrast the present treatment with the conventional SCBA for long-range disorder.

Using the symmetry-suggested decomposition for the self-energy
\begin{equation}
\Sigma=\Sigma_0+\Sigma_1{\bm \sigma}\cdot\bm{n}_{\bm p},
\end{equation}
where $\bm{n}_{\bm p}$ is the unit vector in the direction of $\bm{p}$, and introducing  $\xi_\pm=\varepsilon-u\pm i0$, for the retarded component we have
\begin{eqnarray}\label{SCBA-0}
&&\hskip-.25cm\Sigma_0(p)=\frac{2}{\pi}\int^{\infty}_{0}dqq^2\int^{+1}_{-1}dx\frac{\kappa w^2g_0(q)}{(p^2+q^2+\kappa^2-2pqx)^2}\nonumber\\
&&\hskip-.25cm-w^2g_0(p),\\
&&\hskip-.25cm\Sigma_1(p)=\frac{2}{\pi}\int^{\infty}_{0}dqq^2\int^{+1}_{-1}dx\frac{\kappa w^2xg_1(q)}{(p^2+q^2+\kappa^2-2pqx)^2}\nonumber\\
&&\hskip-.25cm-w^2g_1(p),\label{SCBA-1}
\end{eqnarray}
where we have introduced
\begin{eqnarray}
g_0=\frac{\xi_+-\Sigma_0}{(\xi_+-\Sigma_0)^2-(vp+\Sigma_1)^2},\\
g_1=\frac{vp+\Sigma_1}{(\xi_+-\Sigma_0)^2-(vp+\Sigma_1)^2}.
\end{eqnarray}

To simplify equations, we first introduce new functions $X_p=\xi_+-\Sigma_0$ and $Y_p=vp+\Sigma_1$. Second, we complete $x$-integration in Eqs.~(\ref{SCBA-0}) and (\ref{SCBA-1}) and observe that upon changing $q\to-q$ the corresponding integrands are even and odd functions respectively. We thus extend the $p$-integration to the whole axis such that $X_p$ is considered as an even function while $Y_p$ is odd. As a result we have to solve the following set of coupled integral equations
\begin{eqnarray}\label{eq:XY}
&&\hskip-.75cm
X_p=\xi_+-\frac{\kappa w^2}{\pi}\int^{+\infty}_{-\infty}
\frac{K_0(p,q)X_qdq}{X^2_q-Y^2_q}+w^2\frac{X_p}{X^2_p-Y^2_p},\nonumber\\
&&\hskip-.75cm
Y_p=vp+\frac{\kappa w^2}{\pi}\int^{+\infty}_{-\infty}\frac{K_1(p,q)Y_qdq}{X^2_q-Y^2_q}-w^2\frac{Y_p}{X^2_p-Y^2_p},
\end{eqnarray}
where the kernels are given explicitly by
\begin{equation}
\begin{split}
&K_0(p,q)=\frac{q}{p}\frac{1}{(p-q)^2+\kappa^2},\\
&K_1(p,q)=\frac{q}{p}\left[\frac{1}{(p-q)^2+\kappa^2}+\frac{1}{4pq}\ln\left(\frac{(p-q)^2+\kappa^2}{(p+q)^2+\kappa^2}\right)\right].
\end{split}
\end{equation}

\subsection{$\kappa\to0$ limit within the self-consistent Born approximation and Keldysh model}

It is instructive to understand how the limit of very long correlation length, $\kappa\to0, w=\text{const}$, is reached within various approximation schemes. Firstly, the results for the Keldysh model, Eqs.~(\ref{G}) and (\ref{eq:oldDoS}), are exact in this limit, as we have already discussed. In particular, this means that the quantities $X$ and $Y$, that determine the self-energy at the SCBA level for the modified disorder correlator, must attain bare values $X_p=\xi_+$, $Y_p=vp$ when Eqs.~(\ref{eq:XY}) are solved. That this is indeed the case can be seen noting that in the $\kappa\to0$ limit the kernels $K_{0,1}$ satisfy
\begin{equation}
\begin{split}
&\lim_{\kappa\to 0}\frac{\kappa}\pi K_{0,1}(p,q)=\delta(p-q).
\end{split}
\end{equation}
This implies that the second terms on the right hand sides of Eqs.~(\ref{eq:XY}) are exactly cancelled by the third terms. In fact, all self-energy corrections for the modified disorder correlator, not just the SCBA ones, vanish in the $\kappa\to0$ limit: This is the essence of the Keldysh model, in which the full diagrammatic series is summed up \emph{exactly} in the $\kappa\to 0$ limit, to yield Eq.~(\ref{G}) for the Green's function.~\cite{Efros,Sadovskii}

We can contrast the Keldysh model with the conventional SCBA, in which the full disorder correlator, Eq.~(\ref{eq:fulldisorder}), is used as the impurity line. This approximation can easily be obtained from Eqs.~(\ref{eq:XY}) by setting $\xi\equiv\epsilon-u\to\epsilon$, and dropping the third terms on the right hand sides of the equations for $X$ and $Y$. To distinguish this case from the rest of the paper, we denote $X$ and $Y$ for SCBA with full disorder correlator as $X^{B}$ and $Y^{B}$. To obtain simple analytic results, we limit ourselves to $\epsilon=0$. In the $\kappa\to 0$ limit the SCBA equations are
\begin{eqnarray}
&&\hskip-.75cm
X^B_p=i\delta-w^2
\frac{X^B_p}{(X^B_p)^2-(Y^B_p)^2},\nonumber\\
&&\hskip-.75cm
Y^B_p=vp+w^2\frac{Y^B_p}{(X^B_p)^2-(Y^B_p)^2}.
\end{eqnarray}
The infinitesimal $\delta$ is kept as a reminder that $\Im X_p>0$. $X^B_p$ and $Y^B_p$ can be easily found noting that the former is purely imaginary, while the latter is real:
\begin{eqnarray}\label{eq:solutionXY}
&&\hskip-.75cm
X^B_p=i\theta(2w-vp)\sqrt{w^2-\frac{(v p)^2}{4}},\nonumber\\
&&\hskip-.75cm
Y^B_p=\frac{vp}2+\theta(vp-2w)\sqrt{\frac{(v p)^2}{4}-w^2}.
\end{eqnarray}

The corresponding DoS can be found as
\begin{equation}
  \nu^B(\epsilon=0)=-\frac{2}\pi\Im\int\frac{d^3p}{(2\pi)^3}\frac{X^B_p}{(X^B_p)^2-(Y^B_p)^2},
\end{equation}
which upon using Eqs.~(\ref{eq:solutionXY}) gives
\begin{equation}\label{eq:nuBorn}
  \nu^B(\epsilon=0)=\frac{w^2}{2\pi^2 v^3}.
\end{equation}
In this treatment inter-valley scattering is neglected, and the result Eq.~(\ref{eq:nuBorn}) should be understood as the DoS per node.

We see that the SCBA with the full disorder correlator reproduces the exact answer for DoS in $\kappa\to0$ limit. This means that if one naively tries to correct SCBA result for DoS by including the low-order interference corrections to the self-energy, \cite{Ominato-2} the result will become worse, not better.

What the conventional SCBA does not capture is the form of the spectral weight that results from summation of the full diagrammatic series in the $\kappa\to0$ limit. As a function of momentum for a given energy $\epsilon$, the spectral weight for the Green's function of Eq.~(\ref{G}) is a Gaussian peak centered at $|\epsilon/v|$, having a width of $~w/v$. This exact result is clearly not reproduced by the conventional SCBA at low energies, Eq.~(\ref{eq:solutionXY}). For illustration purposes, we plot the total spectral weight (for conduction and valence bands) at zero energy energy for the retarded Green's function within the Keldysh model, Eq.~\ref{G}, and for the Green's function in the conventional SCBA. The latter is obtained using Eqs.~(\ref{eq:solutionXY}) as $G^R(\epsilon=0,\bm{p})=(X^B-Y^B{\bm \sigma}{\bm n}_{\bm{p}})^{-1}$.

\subsection{Leading correction to the semiclassical density of states}

In this Section we calculate the leading order correction to the semiclassical DoS, Eq.~(\ref{nu}). To this end we use Eqs.~(\ref{eq:XY}) to find the first perturbative correction to $X_p$ and $Y_p$, that is, restric ourselves to the first Born approximation. It is sufficient to find the leading $O(v\kappa/w$) term in the DoS. To zero order in $w$ we take $X_p=\xi_+$ and $Y_p=vp$ and seek the first order correction by iterations:
\begin{eqnarray}
&&\hskip-.75cm
\delta X_p=-\frac{\kappa w^2}{\pi}\int^{+\infty}_{-\infty}\frac{\xi_+K_0(p,q)dq}{\xi^2_+-(vq)^2}+w^2\frac{\xi_+}{\xi^2_+-(vp)^2},\\
&&\hskip-.75cm
\delta Y_p=\frac{\kappa w^2}{\pi}
\int^{+\infty}_{-\infty}\frac{vqK_1(p,q)dq}{\xi^2_+-(vq)^2}-w^2\frac{vp}{\xi^2_+-(vp)^2}.
\end{eqnarray}
After performing the integrations and after some further algebra we find
\begin{eqnarray}
&&\hskip-.45cm
\delta X_p=w^2\left[\frac{\xi_+}{\xi^2_+-(vp)^2}-\frac{\xi_+}{(\xi_++iv\kappa)^2-(vp)^2}\right],\\
&&\hskip-.45cm\delta Y_p=\frac{w^2}{vp}\left[\frac{(vp)^2+(v\kappa)^2-iv\kappa\xi_+}{(\xi_++iv\kappa)^2-(vp)^2}-\frac{(vp)^2}{\xi^2_+-(vp)^2}\right]\nonumber\\
&&+\frac{iw^2v\kappa}{2(vp)^2}\ln\left(\frac{\xi_++iv\kappa+vp}{\xi_++iv\kappa-vp}\right).\end{eqnarray}
These expressions appear very singular, but one must bear in mind that it is only the full disorder-averaged Green's function that determines the DoS, and all singularities of the present perturbation theory are removed by Gaussian integration over $u$ in the expression for the retarded Green's function, Eq.~(\ref{Gfull}), expanded in the usual series in powers of $\Sigma$.

Knowledge of $\delta X_p$ and $\delta Y_p$ allows one to find correction to the density of states. We are only interested in the leading $\delta\nu\sim O(\kappa v/w)$ correction. Explicit calculation shows that the only term contributing to the DoS correction is $\delta\nu\propto\Im \sum_p g_0g_1\delta Y_p$. Following the standard path (expanding the Green's function to linear order in $\kappa$, taking its imaginary part, and performing the final momentum integrations), one finds
\begin{equation}
\delta\nu(\varepsilon)= \frac{w^2}{4\pi^2 v^3}\Im\frac{v\kappa}{\varepsilon-u+i0}.
\end{equation}
Finally, averaging this result with $F[u]$ from Eq.~(\ref{P}) we arrive at
\begin{equation}\label{nufinal}
\frac{\delta\nu(\varepsilon)}{\nu(0)}=-\sqrt{\frac{\pi}{8}}\frac{v\kappa}{w}\exp(-\varepsilon^2/2w^2).
\end{equation}
Thus the first perturbative correction to the DoS is regular and controlled by the smallness of $v\kappa/w$, as expected from the preceding discussion. We note that at no point did we have to introduce an artificial momentum cut-off, as is commonly done while treating the system in the self-consistent Born approximation. Taking into account the second Born approximation, or the first interference correction to the self-energy all lead to DoS-corrections that involve at least one additional power of $v\kappa /w$ compared to Eq.~(\ref{nufinal}), and can be ignored in the current treatment.

In order to establish the limits of validity of our results we need to determine the typical value of $w$. This can be done with the help of self-consistent Thomas-Fermi approximation. First recall that $\kappa=\sqrt{4\pi e^2\nu/\epsilon}$ and $w^2=2\pi ne^4/\epsilon^2\kappa$, which follows from Eq.~(\ref{uu}). Using now Eq.~(\ref{nu}) for the density of states we find an equation that defines the typical magnitude of the disorder potential fluctuation as a function of density $n$ in the form
\begin{equation}
w^4(\varepsilon^2+w^2)=\frac{2\pi^3}{g}\alpha^3n^2v^6,
\end{equation}
where $\alpha=e^2/v\epsilon$ is the effective interaction parameter. The most interesting case for us is the vicinity of the ``neutrality'' point where $\varepsilon\ll w$, so that
\begin{equation}\label{w}
w\simeq v\alpha^{1/2}n^{1/3},
\end{equation}
which sets the typical scale of the density of states and inverse screening length, respectively,
\begin{equation}\label{nuandkappa}
\nu\simeq\alpha n^{2/3}/v,\quad \kappa\simeq\alpha n^{1/3}.
\end{equation}
As discussed above, the Gaussian model of disorder amounts to a condition $n\kappa^{-3}\sim1/\alpha^3\gg1$. Perturbative treatment of the short-range disorder requires $v\kappa/w\sim\sqrt{\alpha}\ll1$. Both of these conditions can be satisfied provided that $\alpha<1$. Finally, we discuss validity of the semiclassical approximation that requires $|d\lambda/dx|\ll1$. The latter can be estimated as follows, $d\lambda/dx\sim(v/u^2)(du/dx)\sim(v/w^2)(w/\kappa^{-1})\sim\sqrt{\alpha}\ll1$.

\subsection{DoS in weak magnetic fields}

This semiclassical formalism can be readily extended to the case of finite magnetic field. The generic analysis of the density of states is quite involved. Here we will be primarily interested in the regime of weak fields, when magnetic length $l_B=\sqrt{1/eB}$ is large compared to the correlation radius of the disorder potential $l_B\gg\kappa^{-1}$. In this case we can use the same approach we have used for the magnetic-field-free case. In the strong-field limit, $l_B\ll\kappa^{-1}$, the treatment of Ref.~\onlinecite{Raikh} should be used. (See also Ref.~\onlinecite{Song2015} for an alternative quasiclassical approach to transport in the strong-field limit.)

The spectrum of Landau levels for the three-dimensional Weyl equation has the form
\begin{eqnarray}
  \varepsilon_m(p_z)&=& \pm\sqrt{\frac{2v^2}{l^2_B}|m|+(vp_z)^2},\quad m=1,2\ldots \\
  \varepsilon_0(p_z) &=& vp_z,
\end{eqnarray}
where we chose a particular chirality for the zeroth Landau level without loss of generality. We concentrate on the lowest energy limit where
\begin{equation}
\nu(0)=\frac{g}{2\pi l^2_B}\int^{+\infty}_{-\infty}\frac{dp_z}{2\pi}\sum^{+\infty}_{m=-\infty}\delta(\varepsilon_m(p_z)-u).
\end{equation}
Averaging this expression over $u$ with the help of Eq.~(\ref{P}), followed by the Gaussian integration over momentum $p_z$ and the geometrical series summation over $m$ one finds
\begin{equation}\label{nu-B}
\nu(0)=\frac{g}{(2\pi l_B)^2}\frac{1}{v}\coth\left(\frac{v^2}{2l^2_Bw^2}\right).
\end{equation}
Expanding this result in the low field limit one recovers Eq.~(\ref{nu}) to the lowest order with a \emph{positive} correction term $\delta\nu/\nu(0)=(v/l_B)^4/12w^4\propto B^2$. This finite field correction ultimately renders the change in the screening radius of the disorder potential, which in the case of Coulomb impurities will have an important effect on magnetoconductivity.

\section{Transport}

In this section we briefly discuss what self-consistent theory of screening in WSMs gives for the low-temperature transport, namely we concentrate on the regime of $T\ll vn^{1/3}$. In the semiclassical limit, provided that the mean free path $l$ for electron scattering is large, $k_Fl\gg1$, where $k_F$ is the Fermi momentum, the conductivity can be calculated from the Drude formula with energy dependent scattering time $\tau(\varepsilon)$, density of states $\nu(\varepsilon)$, and cyclotron frequency $\omega_c(\varepsilon)$,
\begin{equation}\label{sigma}
\sigma(B)=\frac{e^2}{6\pi}\int\frac{d\varepsilon}{4T\cosh^2\left(\frac{\varepsilon-u}{2T}\right)}\frac{v^2\nu(\varepsilon)\tau(\varepsilon)}{1+\omega^2_c(\varepsilon)\tau^2(\varepsilon)}.
\end{equation}
The ensemble-averaged transport scattering time for Coulomb impurities within the Boltzmann approximation can be calculated using the full disorder correlator, Eq.~(\ref{eq:fulldisorder}), since the $\delta(\bm{q})$ part of $D(\bm{q})$ from Eq.~(\ref{impurityline}) cannot lead to momentum transfer. The transport scattering time is thus given by
\begin{eqnarray}\label{tau}
&&\tau^{-1}=\frac{\pi\nu n}{2}\int^{\pi}_{0}d\theta|\phi(2k_F\sin\theta/2)|^2\sin\theta(1-\cos^2\theta)\nonumber\\
&&=\frac{\pi^3\alpha^2\nu nv^2}{k^4_F} [(2a^2+1)\ln(1+a^{-2})-2],\label{tau}
\end{eqnarray}
where $a=\kappa/2k_F$ and $\phi(q)$ is the Fourier transform of Eq.~(\ref{u}) taken at momentum $q=2k_F\sin\theta/2$, whereas the semiclassical expression for the cyclotron frequency for the linear spectrum is
\begin{equation}
\omega_c=v^2/(l^2_B\varepsilon).
\end{equation}
According to our earlier estimates of the screening radius one immediately concludes that $\kappa/k_F\sim\sqrt\alpha\ll1$, so it is sufficient to retain only the large logarithmic factor in Eq.~(\ref{tau}). Then, the zero field conductivity is estimated (up to an overall numerical factor) as follows
\begin{equation}\label{sigma-B-0}
\sigma\simeq e^2v^2\nu(u)\tau(u)\simeq \frac{e^2n^{1/3}}{\ln(1/\alpha)},
\end{equation}
where we took the typical value of potential $u\sim w$ and used Eq.~(\ref{w}). One can check that derived expression indeed corresponds to the Boltzmann limit. We note in passing that a local conductivity tensor is appropriate for the situation considered here, since Eqs.~(\ref{w}), (\ref{nuandkappa}), and (\ref{tau}) imply that $v\tau\kappa\sim1/|\ln\alpha|\ll 1$; in other words, the transport mean free path is much shorter than the screening length.  Further, it is worth mentioning that the dependence of $\sigma$ on the interaction parameter $\alpha$ was a subject of controversy since different results exist in the literature.

The field dependence of the conductivity comes from two factors. The first is obviously due to the cyclotron motion, which we estimate by expanding the denominator of Eq.~(\ref{sigma})
\begin{equation}\label{sigma-B-a}
\frac{\delta\sigma(B)}{\sigma}\simeq -[w_c(u)\tau(u)]^2\simeq-\frac{1}{\alpha^7\ln^2(1/\alpha)}\frac{1}{l^4_Bn^{4/3}}.
\end{equation}
Curiously, there is another contribution, of the opposite sign, that stems from the already mentioned fact, that magnetic field modifies the screening radius. Since the product $\nu\tau$ is inversely proportional to $\ln(k_F/\kappa)$ and $\kappa\propto\sqrt{\nu}$ then it follows from the low field asymptotic of Eq.~(\ref{nu-B}) that for this mechanism
\begin{equation}\label{sigma-B-b}
\frac{\delta\sigma(B)}{\sigma}\simeq\frac{\delta\kappa(u)}{\kappa\ln(1/\alpha)}\simeq\frac{1}{\alpha^2\ln(1/\alpha)}
\frac{1}{l^4_Bn^{4/3}}.
\end{equation}
For weak interactions, $\alpha\ll1$, Eq.~(\ref{sigma-B-a}) always dominates by a parametrically large factor and leads to positive magnetoresistance at weak field that eventually crosses over to quantum regime at higher fields, $\sigma(B)\sim (e^2/v)nl^2_B$. \cite{Abrikosov,Klier} However, for some material systems, where interaction is moderately strong, $\alpha\sim1$, one in principle could envision a scenario where the fate of the sign of magnetoconductivity will be determined by the overall numerical prefactors in Eqs.~(\ref{sigma-B-a}) and (\ref{sigma-B-b}). Obviously the criterion $\alpha\lesssim1$ limits the applicability of our estimates.

An elaborate theory of magnetoresistance in WSMs was recently developed in Ref.~\onlinecite{Klier} in various regimes determined by the relation between the relevant energy scales $T$, $v/l_B$, and $vn^{1/3}$. Our estimates for $\delta\sigma(B)$ at weak field are consistent with that of Ref.~\onlinecite{Klier} with an addition of the contribution governed by Eq.~(\ref{sigma-B-b}), where in Eqs.~(\ref{sigma-B-0})--(\ref{sigma-B-b}) we also retained functional dependence on the interaction parameter $\alpha$.

\section{Summary}

To conclude, we have studied the density of states and transport properties of Weyls semimetals with the long-range Coulomb disorder. Provided that the semiclassical limit is satisfied, DoS induced by the long-range disorder potential fluctuations can be found exactly. In addition, we have developed systematic perturbation theory to account for corrections due to the short-range scattering. Concerning the transport properties, for weak interactions and magnetic field the magnetoresistance is expected to be positive for a single Weyl node. (As compared to a negative magnetoresitance for current flow along the magnetic field when the realistic multivalley situation is considered. \cite{Son-Spivak}) However, based on the presented analysis, one should not exclude a possibility of nonmonotonic magnetoresistance in systems with relatively strong interactions.

Yes do! Just ordered from Eurospares. Got dispatch confirmation and Fedex number. Then about 2 hours later an email telling me they couldn't find the part.
Ross was a star as ever.
I don't use Eurospares...Ill leave that there!
Can't remember who it was now, but seen a QP at the ACE in the past with a DIY mesh grill made by removing the slats on the normal QP grill and adding their own grill, then painting all black.
I've also looked and found one in a breakers in California but it was eye watering even before P&P so didn't progress. Quite like the mesh, but can't see it once you're in the car!
I'm actually in two minds over the mesh, I have the chrome slatted, and I understand there are (were) two types of mesh grille, black one and chrome one. Think I prefer the chrome one, the black one makes the QP and bit like Jaguar XJF to me.
The sat Nav is rubbish anyway, wait for our fearless leader to produce the sports Maserati apple and android car play screen update, buy that, install it and use google maps, Waze or whatever. Don't waste time and money on a system from 1973.
Have you got access to an SD3 to set the clutch up with?
I won't change it myself, my mechanic has everything he needs for a clutch change, he's a Ferrari/Maserati specialist.


Hi. I've tried to abstain from PMO several times, but I always relapse then give up. I'd like to not give up this time. I'm sick of this addiction. It's not part of who I'd like to be.
I will update this journal at least every week, if not more.

Hi, it has been quite a while since I've posted on here. I have been struggling with beating this and I think it would be helpful to post on here often. I feel like I've been wasting a lot of my days lately and haven't been very happy. I haven't been that productive, the only productive thing I've been doing is going to school. I skipped it today though. I need to actually make some changes in my life, I always say I will but never do, maybe I need to take smaller steps.
We're still here for you. Don't stop!
This recovery, take it "one day at a time". Get up, look yourself in the mirror, and say "just for today".
Start a Journal and update it regularly. Like here in this thread is a great place. It gives you a history so that you can see where you've been, where you are, and where you are going.
Find an AP. You may start a thread in the "Accountability Partner" Forum to get that ball rolling.
Get and read "Out of the Shadows" by Dr. Patrick Carnes. He is the world's foremost expert on this addiction.
Lean on your support for help. There is an abundance of it here. If you have someone you can confide in (be very very careful on this one), then that too would be a good place to get help when you need it most.
That is it for now. If you have questions, ask. If you need help, ask. Whatever guilt, shame, and embarrassment you carry, bring it here and dump it in our lap. Let us take that away from you.
That's it for now. If you want/need anything, you know how to find me.
Today has been okay. I went to school and the store after, which was a distraction from urges. I did have urges today, but my thoughts were that although I have them, I don't have to act on them. I don't have to MO or search P. I can continue with my current task and the urges will pass.
"7 Years" by Lukas Graham started playing I was in the car earlier and the lyrics made me think how fast life goes by and how I should be making the most of it. Great things can happen.
To be honest, I don't have any friends. I am too nervous to talk to anyone besides family and when I do talk to anyone else, it comes out as a mumble or whisper unless I get called on to answer a question in class. This is due to me being isolated and not really doing much, which is something I want to change. Something I will overcome along with this addiction.
I also read a plan on a Bible app called YouVersion. Getting close to God is something I would love to do.
I also read a bit about minimalism, which is also something I'd like to incorporate into my new lifestyle.
Anyways, I'm going to make a plan before I go to sleep. I need to keep myself occupied if I want to overcome PMO and I don't want to feel lost all the time. Self improvement, including quitting PMO, had been something I've been attempting for years now but I haven't succeeded yet, which is very disappointing, but I just need to keep trying.
Thank you very much for the advice, I will definitely follow it.
Hi everyone, today was a fine day. I did have urges, but I didn't give into them. I went without my phone and laptop for about half of the day and spent my time reading and writing instead, which was nice.
Post an entry on this thread.

Good luck in our journey, it's something difficult but for sure not impossible.
It's when you realize how beautiful life is when you look for happiness in things that make you feel full.
In my case it helps me when I appreciate them, the sun, a smile, a song, saying thank you, a laugh, forgiving someone...If we achieve that our looking and view of things change so that we can see people in a beautiful and deep way, (as what they really are, as persons and admire them as they are) admire their inside beauty, but also the outside one with pure eyes, we will win. We will be also able to admire us totally and transmit it to the people around us. I would recommend you that everyday you look yourself in a mirror and smile, you will feel you have a lot of value and you will be able to look the beauty in you, also through your eyes and your looking.
I am Christian and it helps me a lot also contemplating the love of God, it's something that makes me see things differently and be separated from PMO. Also confessing it's something incredible.
I think our goal is to find love in the pure way.

Thank you! I wish you good luck in your journey and I'm here to help as well. You are right, life has so many beautiful things to offer and people are very admirable. Appreciating small things is so important.
God's love also helps me see things differently. He is so wonderful.
Nice plan, it's good to stay busy and involved in happy recreational activities as well. Cheers!
Hi everyone. Today was a nice day, I did have small urges here and there but thinking of God and reading the Bible helped me.
Psalms 4:4: Tremble and do not sin, when you are on your beds, search your hearts and be silent.
I also was thinking that some reasons I have been feeling sad lately are because I compare myself to others and always want to be like them, which leads me spending hours searching for other people's methods of self improvement instead of actually acting on what I want to do. :/ It's also kind of an excuse to not do anything, but I will stop doing it. It wastes too much time.
I'm going to try to be more positive and appreciate more of the good things in life, looking at the good in everything that happens to me each day. Negativity will not only push me away from God, but it will make me more vulnerable to this addiction and prevent me from doing the things I'd like to do, which is not something I want for myself anymore.
Anyway, today I also read 20 pages of Warcross (which is a good book so far) and watched about an hour's worth of Crash Course Theater videos.

Good, you're sticking to your plans. Excersising discipline is a must. It's good to be purpose full with our thoughts by keeping them focused on good and productive things.

I really like this. You can also put that in calendar format, and @FlyingPizza has an incredible illustration of it in her journal. Seek it out. I think you'll be impressed.

What a scorcher! We started out prompt at 8.55am to get some miles behind us before the heat of the day. At Fish Hill we were thrilled to be joined by Jan and Chris from Pershore IW who walked into Broadway with us for some lunch. Then Banbury member Alison and husband Martin joined us for a few miles. Two tumbles today but luckily no injuries sustained! Very hot and bothered by the time we checked into the hotel at 5pm.
Another hot day for walking but we made good time arriving at Winchcombe for lunch at midday. On our way we spread some International friendship with a nice chat with four Belgian ladies. Fortunately the sky clouded a little in the afternoon making our final climbs easier. We took no chances today after some serious dehydration issues yesterday!
meant over an hour's walk to find the path! We had fantastic support from Marg (Worcester Severn IW) and Margaret & Moira (North Wiltshire IW) who walked with us today. It was tough all the way with high humidity and the only pub en-route with a closed kitchen. Our saviours were a lovely couple who provided coffee and teacakes on their lawn! The romantic highlight was a visit to 'Devil's Chimney' - the site of an historic marriage proposal 31 years ago. It took until 6pm to get to our very welcome baths tonight.
A lovely sunny day and lots of woodlands to keep us cool, making it more comfortable to cover our miles. Our lunch stops don't just give us a chance to re-fuel but also to re-plaster our feet for protection! We were joined by Marg again for the morning and also Wendy, D10 Secretary (Stroud IW) who not only walked but also met us at 6.30pm and drove us off the path and into our hotel - what a star. The afternoon saw us confronting a herd of cows determined to walk down the path towards us. Clare soon sorted them out! Fabulous views from our high points all the way to the River Severn and the Malvern Hills.
A tricky start to the day when our valiant luggage driver, Stephen's car broke down just as he dropped us at our start point. Luckily the AA came to the rescue and we then got underway. A long haul up and down hills but lovely views to reward us and more peaceful woodlands to explore. We managed to dodge all the expected rain showers but heard the thunder rolling around us. Banbury Club President, Helen came to meet us at Dursley for a late lunch and then we had a short afternoon before being collected and driven to our hotel by Annie's husband, Martin who is on duty over the weekend!
After missing dinner last night and going to bed with dehydration & exhaustion Linda was glad to be up and about this morning. We romped uphill to the William Tyndale monument and then down again into Wotton Under Edge for coffee. The DC admired the hanging baskets and wondered if she had found a hat fit for the Rally! Nowhere else to get food today so we stocked up and then made our way through country lanes, fields and more woodland, once again dodging all the showers. Paused for our sandwiches on a bench in the hamlet of Alderley and then the sun came out as we climbed more hills and descended into Hawkesbury. Our shortest day so far but more to do tomorrow. What the photos do not show is the aching feet and legs or the number of painkillers now being consumed daily!
We set off early at 8.30 for another long day. Lovely sunshine and our route today took us along much easier ground, only a few climbs and lots of fields and meadows which were fairly level. It made a big difference to the legs! We paused for a drink at Old Sodbury and then lunch at a pub in Tormarton. After making good time we sneaked an ice cream at the NT property; Dyrham Park. Annie put her feet up while we rested in the shade. We then had to detour off the path to find our farmhouse B&B for the night and Dave heroically navigated us safely across fields of cows! Driving out for our last dinner this evening to set ourselves up for the final push into Bath tomorrow.
Awoke to more glorious sunshine and another great breakfast. We walked without a stop all day across fields and the last of the countryside until we reached the outskirts of civilisation. A final climb in Bath and then descending past the Royal Crescent and into the city centre. What a wonderful surprise to be met by Hildegarde, President of Bath IW and our very own MOC, Anne who had travelled from Wokingham to greet us at the finish. We were joined too by Tom from Send a Cow's HQ in Bath, who arrived in time to see us kiss the Abbey doors - a sign that our journey was over!
Ladies should never do more than perspire a little but we have sweated buckets over the past eight days! We couldn't have done it without the support of three tremendous husbands who have transported our luggage or walked and map read along the way, or without the moral support and friendship of so many IW friends, particularly Clare who has walked the whole route with us.
