The Revenge of "Volgograd Obama"
"Screw you, United Russia!"
Remember Joaquim Crima, the so-called "Volgograd Obama"? The last we heard from the simple watermelon seller turned political candidate was back in 2009 when he ran for office on the United Russia ticket in Srednaya Akhtuba. The novelty an Afro-Russian candidate bequeathed Crima fifteen minutes on the world stage. He was featured in both the Russian and international media. His fame even spawned a "virtual" challenger, Fillip Kondratevto, to his moniker as Russia's Obama. His fame even got him an audience with Vladimir Putin last summer. It was assumed, or at least I assumed, that that was the last we'd ever hear from him since I had a sneaking suspicion that Volgograd's Obama was nothing more than a flash in the pan publicity stunt.
I guess I assumed too soon.
The "Volgograd Obama" is back and and just as his political aspirations thrust him into the news, so has his latest move: dumping United Russia. "I request to cease my membership in the party United Russia," reads a hand scrawled note, littered with spelling mistakes. It didn't take long for Crima to find a new political home as a member of Just Russia. "The admission of Vasilii Crima into the ranks of Just Russia is surely a significant event," says Sergei Klimenkov, a Just Russia secretary. And why did Crima, who had been a member of United Russia since 2007 and once said that "I think that if the country had a hundred of such people like Putin, Russia would be the first in the world," suddenly switch sides, and no less on the eve of United Russia's regional party congress?
The answer lies in Crima's open letter to Putin. Obviously composed by Just Russia spin doctors, it might might go down as an archetypal expression of "loyal opposition." Criticize the locals for excessive bureaucratism and indifference to the masses (an old Soviet trope by the way), but show deference and, as Crima puts it, staunch support for the course laid out by, and the order of names are key here, Putin and President Medvedev.
"This guy doesn't look like no damn Obama."
Also, are we really to believe that Crima amassed 20 tons of watermelons to send to fire stricken Moscow!? You gotta be kiddin' me. What did he expect villagers were going to do with 20 tons of melons? Throw them on the fires?
Dear Vladimir Vladimirovich!
Joaquim Rit Cabi Crima is addressing you. Less than a year ago you extended to me, a simple village entrepreneur from the Sredne Akhtubinsk district in Volgograd province, the great honor by inviting me to a meeting which you held in Volgograd. There you asked me if it was better to work in Africa or in Volgograd? Today I would like to answer that question as I did then: it is not important where one works, whether in Africa or Russia, what's important is what one works for, and here everything depends on the person. If a person actively wants to live better, he must always yearn for something greater.
An You, Vladimir Vladimirovich, agreed with me then, and literally said the following, "If we want to live better, then we need to work better–that's the whole point. But in order to work better, we need to understand what's going on."
I thought of your words several times as I was deciding to leave United Russia and join Just Russia. It was this decision that promoted me to write you this letter to explain why I made such an important decision.
Over the last year the support for United Russia has significantly dropped in Volgograd. This isn't just my opinion, our governor recently said this himself. I think that to understand why this has happened we need to look at United Russia's regional office and the situation that has developed in Volgograd province. Volgograd residents have lost faith in the government, in the party of power, and they don't see positive changes in their lives.
For example, among United Russia's campaign program in the last elections for Volgograd's provincial Duma was a promise to increase the pay of state employees, control the prices of essential goods, and prevent the increase in utility costs. None of these promises were fulfilled.
But the money for the increase of state employee salaries exists in the meager provincial budget. Along with this, several of the budget's social clauses were put under the knife. The introduction of the institution of city manager in Volgograd has not added to the authority of United Russia's regional office–the population of a metropolis has lost its right to elect its city leaders.
I became convinced by personal experience that United Russia is more and more becoming a party of bureaucrats. I will give you just one example. Last summer when the horrible fires raged, I came up with an idea to give humanitarian aid to two villages in Moscow province that had severely suffered from the fires. This was a simple, normal desire to help people. I managed to collect 20 tons of watermelons. All that remained was sending them to Moscow. I requested help from United Russia's regional leadership several times, but it was all in vain–just blank walls of incomprehension and indifference to a stranger's misfortune. The watermelons simply rotted.
United Russia has talked a lot about needing concrete action in the interests of society. Unfortunately, in my opinion, United Russia has recently moved farther and father from its principles. Concrete political work had been exchanged for well known administrative resources, people have lost their right to vote, and there is an eternal struggle for power between members. United Russia's political monopoly has not only become a hindrance on path to democratizing our country, but also the source for making decisions that are contrary to the interests of society. This is especially clear in Volgograd province.
That's why I have decided to leave United Russia. My humble desire to be useful to the party remains unclaimed. And to just possess a party card is not for me.
Dear Vladimir Vladimirovich! Though I am no longer a member of United Russia, I remain a staunch supporter of the course of Russia's modernization that you and President Dimitry Medvedev have taken. This course, I am sure is also shared by Just Russia. Hopefully, I will not be superfluous in its ranks.

Bill Nighy and Chris Geere are the latest stars to join the cast of 'Detective Pikachu'.
Ryan Reynolds is already on board to star in the first live-action Pokemon franchise movie, along with 'Inception's Ken Watanabe, 'The Get Down's Justice Smith and 'Big Little Lies' star Kathryn Newton.
Now Deadline has reported that 'Love Actually' star Bill and 'You're The Worst' actor Chris have also joined the cast.
'Detective Pikachu' is set to follow Smith's teenage character Tim Goodman, who has to team up with the mouse-like Pikachu in order to find his father who has been kidnapped.
Newton is set to star as a journalist.
In the movie based on the gaming franchise, Pikachu isn't as agile as the normal fan favourite Pokemon, so has to rely on his intelligence to beat his enemies, and he gets help from Tim - who is the only boy who can understand what the he says - to solve Pokemon-related crimes.
'Goosebumps' director Rob Letterman is set to helm the new movie and has teamed up with Legendary Entertainment to oversee the upcoming movie which has been written by 'Guardians of the Galaxy's Nicole Perlman and Alex Hirsch who has worked on 'Gravity Falls'.
Rather than a standalone film it is expected that 'Detective Pikachu' will act as a launch pad for a new franchise.
The Pokemon Company's long-standing movie collaborator, Toho, will handle distribution of the film franchise in Japan, as it recently worked in partnership with Legendary on the reboot for the 'Godzilla' franchise.

\section{Introduction}
It is very useful to classify quantum magnets
according to the symmetry (if any) that is
broken in the ground state. When the SU(2) symmetry
is broken, the system usually sustains some kind of long-range
magnetic order, although some more exotic examples
involving quadrupolar order have been recently discussed\cite{arikawa,laeuchli}.
When the SU(2) symmetry is not broken, a translation symmetry
may or may not be broken depending on the lattice topology.
The standard case in which no lattice symmetry is broken is
that of systems in which it is possible to build  a singlet inside
the unit cell, as for instance in a ladder\cite{dagotto}. If however this is not possible,
as in all systems with half-integer spins and an odd number
of sites per unit cell, the simplest way to keep SU(2) symmetry
is to break the translation symmetry so that the new unit cell
contains an even number of sites per unit cell. The typical example
is the S=1/2 $J_1-J_2$ chain, which has been explicitly shown
quite some time ago by Majumdar and Ghosh\cite{majumdar} to have two-fold
degenerate dimerized ground state when $J_2=J_1/2$.

Another possibility to keep SU(2) symmetry without breaking
any lattice symmetry has been put forward by Anderson\cite{anderson} in 1973.
Concentrating on S=1/2 magnets, he suggested that under
appropriate circumstances the ground state might be a linear
combination of valence bond (VB) states, i.e. states in which sites
are paired to form singlets. Clearly each individual state breaks
at least some of the translational symmetries of the underlying
lattice, but the translational symmetry is restored by the
superposition of such valence bond states. Such a wave
function is known as a Resonating Valence Bond (RVB) state.

To identify such a ground state in realistic models of quantum
antiferromagnets turned out to be much more difficult than
anticipated. The prediction of Fazekas and Anderson\cite{fazekas} that this
might be the case for the S=1/2 Heisenberg model on the triangular
lattice, based on estimates of the energy of ordered and valence
bond states including perturbation corrections, is not supported
by recent numerical investigations, which all point to 3-sublattice
antiferromagnetic order\cite{bernu}.

The most serious candidate still around is the S=1/2 Heisenberg
antiferromagnet on the kagome lattice. No evidence of magnetic
long-range order could be found so far, and the proliferation of
low-lying singlets observed in exact diagonalizations of finite
clusters\cite{lecheminant} can be fairly well described in the short-range RVB
subspace of valence bond states involving only nearest neighbours\cite{mambrini}.
However, several treatments based on some effective Hamiltonian
have reached the conclusion that the ground state support some
kind of valence bond order\cite{syromyatnikov,nikolic,auerbach}, and hence breaks
translational symmetry.
Unfortunately, the resulting unit cell is so large, and the singlet-singlet
gap accordingly so small, that this prediction cannot be cross-checked
by the only unbiased numerical approach available so far, namely
exact diagonalization, and the issue is likely to remain open for quite some
time.

In fact, it has only been possible so far to  unambiguously identify
an RVB ground state in a very minimal description of fluctuations
in the RVB subspace that goes under the name of Quantum Dimer
Model (QDM)\cite{rokhsar}. In this approach, valence bond configurations are assumed
to build an orthogonal basis of the Hilbert space, and the effective
Hamilonian contains kinetic terms that shift dimers around loops
and potential terms that favour or penalize specific local configurations
of dimers. For the triangular lattice, the simplest model is defined
by the Hamiltonian:

\end{center}
\end{figure}
\noindent where the sum runs over all plaquettes including
the three possible orientations.
The kinetic term controlled by the amplitude $t$ changes the dimer covering
of every flippable plaquette, i.e., of every plaquette containing two dimers
facing each other, while the potential term controlled by the interaction $v$
describes a repulsion ($v>0$) or an attraction ($v<0$) between dimers
facing each other. Since a positive $v$ favors configurations without flippable plaquettes
while a negative $v$ favors configurations with the largest possible number of
flippable plaquettes, one might expect a phase transition between two phases as a function of $v/t$.
The actual
situation is far richer though. As shown by Moessner and Sondhi\cite{moessner}, who calculated the
temperature
dependence of the structure factor, there are four different
phases: {\bf i)} A staggered phase for $v/t>1$,
in which the ground-state manifold consists of all non-flippable configurations;
{\bf ii)} A columnar ordered phase for $v/t$ sufficiently negative; {\bf iii)} An ordered phase
adjacent to it  which probably consists of resonating
plaquettes which make a $12$-site unit-cell pattern\cite{ralko2};
{\bf iv)} A liquid phase with a featureless and temperature independent
structure factor. This last phase has been interpreted as a short-range
(RVB) phase in which all correlations decay exponentially at zero temperature,
an interpretation confirmed by recent Green's function Quantum Monte
Carlo simulations\cite{ralko1}, which have established the presence of topological
degeneracy in this parameter range, a clear characteristic of the RVB phase.

This result defines a new line of research in the field: Indeed, rather than investigating
directly the properties of the Heisenberg model on a given lattice, one can
try to identify models for which a VB subspace is a reasonable variational
subspace, derive an effective QDM, and study it
along the same lines as the minimal model on the triangular lattice.
In that respect, a natural candidate is the trimerized spin-1/2 Heisenberg
model on the kagome lattice. An effective model in terms of the total spin
$\vec \sigma$ and a chirality pseudo-spin $\vec \tau$ per strong triangle has
been derived\cite{subra,mila}. It is defined on the triangular lattice built by strong triangles
and can be written\cite{ferrero}:
\begin{equation}
  {\cal H}_0^{{\rm eff}} = \frac{J^\prime}{9}
  \sum_{\langle i,j \rangle}
  {\vec\sigma}_i \cdot {\vec\sigma}_j
  (1 - 4 {\vec e}_{ij} \cdot {\vec \tau}_i)
  (1 - 4 {\vec e}_{ij} \cdot {\vec \tau}_j),
\end{equation}
where $J'$ is the weak coupling between the strong triangles of the
trimerized lattice, and where the vectors ${\vec e}_{ij}$ have
to be chosen among
${\vec e}_1=(1,0)$, ${\vec e}_2=(-\frac{1}{2},-\frac{\sqrt{3}}{2})$,
${\vec e}_3=(-\frac{1}{2},\frac{\sqrt{3}}{2})$
according to the pattern of Fig.~\ref{fg:triankind}.
A mean-field decoupling of spin and chirality has identified nearest-neighbour
valence bond states as the lowest solutions\cite{mila}, and, following Rokhsar and
Kivelson\cite{rokhsar}, a QDM
has been derived\cite{zhitomirsky}. Unfortunately, the properties of this model could not
be studied so far. First of all, they involve kinetic terms on longer loops than
the above-mentioned minimal model, but more importantly, it is impossible
to formulate it in such a way that all off-diagonal matrix elements are negative,
so that the Quantum Monte Carlo methods that were successful for the minimal
model cannot be used.

\begin{figure}
\begin{center}
 \vspace{0.3cm}
 \includegraphics[width=0.3\textwidth]{fig3.eps}
 \caption{\label{fg:triankind}

    (${\vec e}_\mu = {\vec e}_1$), dashed lines (${\vec e}_\mu = {\vec
      e}_2$), and dotted lines (${\vec e}_\mu = {\vec e}_3$).}
\end{center}
\end{figure}

The effective spin-chirality model has another remarkable feature though:
It is formally very similar to the spin-orbital models that are used to describe
Mott insulators with orbital degeneracy. Indeed, as discussed in great details
by Kugel and Khomskii\cite{kugel}, when the local symmetry is such that different
orbitals can be occupied in the open shell of the magnetic ions of a Mott
insulator, this extra degree of freedom can be described by a pseudo spin,
and the resulting model is roughly speaking of the same form. Given the very different
precise forms this model can take for specific systems, a general discussion
cannot be attempted here. Rather, we concentrate in the next section on
a specific example of Mott insulator with orbital degeneracy for which we believe that RVB physics might
be realized. More general comments will be given in the last two sections
of the manuscript.

\section{The spin-orbital model of LiNiO$_2$}
The Mott insulator LiNiO$_2$ and its cousin NaNiO$_2$
are isostructural and isoelectronic. The crystal structure can be envisaged
as a sequence of slabs of edge sharing
octahedra of oxygen O$^{2-}$ ions. Metal ions sit at the centers of
octahedra. There are two kinds of slabs: in A slabs, at every center of
octahedra there is a Ni$^{3+}$, whereas in the B slabs, one finds either
Li$^+$ or Na$^+$ ions. A and B slabs alternate (see Fig.~\ref{ANiO2}).
The Ni ions form well-separated triangular planes.
The Ni$^{3+}$ ions are in the $S=1/2$ low-spin state, which allows for
twofold orbital degeneracy between the $d_{3z^2-r^2}$ and $d_{x^2-y^2}$
orbitals (see Fig.~\ref{ANiO2}).

\begin{figure}[ht]
\begin{center}
\includegraphics*[width=12truecm,angle=0]{fig4.eps}
\caption[ANiO2]{\label{ANiO2}
Left: ANiO$_2$ structure. Ni ions are located in the middle of the O octahedra.
Right: Local structure and degenerate orbitals: $d_{3z^2-r^2}$ (left octahedron) and $d_{x^2-y^2}$
(right octahedron)}
\end{center}
\end{figure}

Surprisingly enough, the two systems have very different properties:
NaNiO$_2$ undergoes a high temperature Jahn-Teller distortion,
followed at low temperature by the antiferromagnetic ordering of
ferromagnetic triangular planes, which makes it a standard example
of orbital ordering followed by magnetic ordering\cite{nanio2exp}.
By contrast,
no ordering could be detected in LiNiO$_2$, and some kind of
freezing seems to take place below 8 K\cite{linio2exp}. The best samples of LiNiO$_2$
are non stoichiometric however, some  Li sites being occupied by Ni atoms, and this has been
invoked to explain the difference. The trend upon approaching
stoichiometry is not clear though, and this striking difference between
the two systems, in particular the lack of any sign of a cooperative Jahn-Teller transition in
LiNiO$_2$, suggests to look for alternative explanations. In the
following, starting from a realistic microscopic
description of the system, we study the possibility to stabilize an RVB
spin-orbital liquid  in the absence of any disorder.

\subsection{Microscopic Model}

A fairly general description of this system is given by
a Kugel-Khomskii Hamiltonian defined in terms of Wannier functions centered
on the Ni sites by two hopping integrals $t_h$
and $t^\prime_h$, the on-site Coulomb repulsion $U$ and the Hund's coupling
$J$ which, on a given bond, takes the form\cite{vernay1}
\begin{eqnarray}
\mathcal{H}_{ij} =
  -\frac{2}{U\!+\!J} \left[
    2 t_h t^\prime_h {\bf T}_i {\bf T}_j
  - 4 t_h t^\prime_h T^y_i T^y_j
    + (t_h-t^\prime_h)^2 ({\bf n}_{ij}^z{\bf T}_i) ({\bf n}_{ij}^z{\bf T}_j)\right.\nonumber\\
+ \frac{1}{2}  \left. (t_h^2-{t^\prime_h}^2) \left( {\bf n}_{ij}^z{\bf T}_i
+ {\bf n}_{ij}^z{\bf T}_j \right) +  \frac{1}{4}(t_h^2+ {t^\prime_h}^2)
    \right] \mathcal{P}_{ij}^{S=0}
\nonumber\\
  -\frac{2}{U -J} \left[
    4 t_h t^\prime_h T^y_i T^y_j
  + \frac{1}{2}(t_h^2+ {t^\prime_h}^2)
  + \frac{1}{2} (t_h^2-{t^\prime_h}^2) \left(
  {\bf n}_{ij}^z{\bf T}_i + {\bf n}_{ij}^z {\bf T}_j
\right)
\right] \mathcal{P}_{ij}^{S=0}
\nonumber\\
  -\frac{2}{U\!-\!3J} \left[  - 2 t_h t^\prime_h {\bf T}_i {\bf T}_j
   -
   (t_h-t^\prime_h)^2 ({\bf n}_{ij}^z{\bf T}_i) ({\bf n}_{ij}^z{\bf T}_j)+
\frac{1}{4}(t_h^2+{t^\prime_h}^2)
    \right] \mathcal{P}_{ij}^{S=1}
\label{eq:effham3}
\end{eqnarray}
with the usual definitions for the projectors on the singlet and triplet states
of a pair of spins:
\begin{equation}
\mathcal{P}_{ij}^{S=0} = \frac{1}{4} - {\bf S}_i{\bf S}_j
\quad\mbox{and}\quad
\mathcal{P}_{ij}^{S=1} = {\bf S}_i{\bf S}_j+\frac{3}{4},
\end{equation}
The vectors ${\bf n}_{ij}^z$ depend on the orientation of the bonds and are given by
${\bf n}_{12}^z=(0,0,1)$,
${\bf n}_{13}^z=(\frac{\sqrt{3}}{2},0,-\frac{1}{2})$ and
${\bf n}_{23}^z=(-\frac{\sqrt{3}}{2},0,-\frac{1}{2})$ for the 3 orientations respectively.
The operators ${\bf T}_i$ are pseudo-spin operators acting on the orbitals.
For the local geometry shown in the right panel of Fig.~\ref{ANiO2}, $t_h$ and $t'_h$ correspond to the hopping between
pairs of $d_{3z^2-r^2}$ and $d_{x^2-y^2}$ respectively, the hopping between
the $d_{3z^2-r^2}$ on one site and the $d_{x^2-y^2}$ on the other being zero by symmetry.
Of course, all bonds are equivalent, but once a basis, i.e. a pair of local orbitals,
has been chosen, the Hamiltonian takes a different form on bonds with different
orientations.
Note that other forms of the microscopic Hamiltonian including explicitly O orbitals
have been used\cite{dare,mostovoy,reitsma} with somewhat different conclusions.

\subsection{Mean-field phase diagram}

Inspired by the results obtained on the trimerized kagome model\cite{mila},
spin and orbital degrees of
freedom can be decoupled in a  mean-field way\cite{vernay1}.
This leads to a phase diagram in which phases can be distinguished
by the mean value of the orbital and/or spin part of the Hamiltonian
on each bond. The resulting phase diagram is remarkably rich (see
Fig.~\ref{var-dia}). Orbital ordering in the ferromagnetic phase has also been discussed
in Ref.\cite{mostovoy}.

\begin{figure}[ht]
\begin{center}
\includegraphics*[width=8truecm,angle=0]{fig5.eps}
\caption[var-dia]{\label{var-dia}{Mean-field phase diagram on a 16-site cluster
as a function of hopping
integral versus Hund's coupling. The grey phase is the ferromagnetic phase,
with the classical phase boundaries between different types of orbital ordering.}}
\end{center}
\end{figure}

While the planes of NaNiO$_2$ are known by now to
be ferromagnetic, suggesting that NaNiO$_2$ is in one of the ferromagnetic phases,
 LiNiO$_2$ is expected to be in one of the antiferromagnetic phases.
The orbital and spin structure of the antiferromagnetic phases is depicted
in Fig.~\ref{phases}, except phase A, which consists of SU(4) plaquettes\cite{penc1}
and cannot be described along these lines.
\begin{figure}[ht]
\begin{center}
\includegraphics*[width=12truecm,angle=0]{fig6.eps}
\caption[var-dia]{\label{phases}{Spin and orbital structure in the singlet
phases of the mean-field phase diagram. Solid line indicates AF, dashed line
FM spin correlations.}}
\end{center}
\end{figure}
Since niether orbital nor magnetic ordering could be detected in LiNiO$_2$, and since
phases B and  D have a simple orbital ordering pattern while phase E is
likely to be antiferromagnetically ordered, let us concentrate
on phases C and C'.
Both phases are characterized by strong dimer singlets
forming different regular dimer coverings of the triangular
lattice. On each dimer the orbitals are parallel, and
they correspond to $d_{3z^2-r^2}$, $d_{3x^2-r^2}$ or
$d_{3y^2-r^2}$ depending on the orientation of the bond.
Note that all these orbitals are Jahn-Teller active,
leading in all cases to two long and four
short Ni-O bonds.
One might be tempted to conclude that these phases
correspond to two types of valence bond solids with
the patterns depicted in Fig.~\ref{phases}. The mean-field
approach has a very remarkable property however: In
addition to the mean-field solutions with lowest energy shown
in Fig.~\ref{phases}, there are several other
mean-field solutions of the self-consistent equations
with energies very close to the lowest energy corresponding
to other dimer coverings of the triangular lattice\cite{BaVS3}.
In such circumstances, going beyond mean-field is likely
to couple these solutions, and the relevant model would
then be a QDM describing resonances between
these states, a point of view
favoured by exact diagonalizations of finite clusters.
So it is more appropriate to think of these
phases as a region of parameters where all dimer coverings
are relevant states for low-energy physics.

\subsection{Effective Quantum Dimer Model}

Starting from all dimer configurations mentioned in the previous section,
a QDM has been derived\cite{vernay2}. It involves a competition
between kinetic processes and dimer-dimer repulsion. A miminal
version of the model is defined by:

\end{equation}
where the sums run over the 4-site and 6-site loops with all possible
orientations. Although the repulsion is a higher order process, hence quite small,
and although the ratio $t^\prime/t$ is in principle fixed by the
perturbative expansion, these parameters are treated as free
to make contact with the Rokhsar-Kivelson model
on the triangular lattice. The main difference with the effective model derived
for the trimerized
kagome antiferromagnet is that the off-diagonal elements are now all {\it negative}. This
is in practice extremely important since it allows one to use Quantum Monte
Carlo simulations.

The phase diagram of the model has been derived using exact diagonalizations
of finite clusters and Green's function Quantum Monte Carlo\cite{vernay2}. As shown before,
the most convenient way to identify an RVB phase is to look for topological
degeneracy since it is at least partially lifted in all other phases. The resulting
phase diagram is shown in Fig.~\ref{fig:phasediag}. It contains a large RVB liquid phase
which connects the relevant parameter range for LiNiO$_2$ ($t'/t \simeq 2$ and $V$ small)
to the RVB liquid phase of the minimal model ($t'=0$). Translated into spin-orbital
language, this RVB phase corresponds to a spin-orbital liquid wiht
no symmetry breaking and no phase transition, in agreement with
the phenomenology of LiNiO$_2$.

\section{Discussion}

Let us now comment on how generic the mechanism proposed in the context
of the spin-orbital model of LiNiO$_2$ might be. The main ingredients to get
an RVB spin-orbital liquid are: 1) The spontaneous formation of dimers;
2) The degeneracy or
quasi-degeneracy of the energies of the wave-functions constructed out of
different dimer coverings; 3) The presence of an RVB phase in the relevant
QDM. Let us comment on these points separately.

The tendency of spin-orbital models to spontaneously form
dimers is well documented. The possibility to stabilize dimerized
 ground states due to orbital
degeneracy has first been put forward by Feiner {\it et al} in the context of
a realistic 3D model\cite{feiner}. Shortly after, the presence of a dimerized
ground state has been explicitly proven  for a simple minimal 1D model by Kolezhuk
and Mikeska\cite{kolezhuk}, a result generalized shortly after by Pati {\it et al}\cite{pati}
in the context of a model defined by the Hamiltonian:

\begin{equation}
H=\sum_{\langle i,j \rangle} \left[J_1 \vec S_i.\vec S_j +J_2 \vec T_i.\vec T_j + K(\vec S_i.\vec S_j )(\vec T_i.\vec T_j )\right]
\end{equation}
with $K>0$. When $J_1/K=J_2/K=3/4$, it can be rewritten as

\begin{equation}
H=K\sum_{\langle i,j \rangle}  (\vec S_i.\vec S_j +3/4)(\vec T_i.\vec T_j + 3/4)
\end{equation}
Each term is obviously positive, and since $\vec S_i.\vec S_j +3/4$
(resp. $\vec T_i.\vec T_j + 3/4$) is the projector on the spin (resp. orbital) triplet,
the two wave-functions with alternating spin and orbital singlets are zero energy
eigenstates, hence ground-states\cite{kolezhuk}. Pati {\it et al} have shown that this dimerized
phase extends to a very large portion of the phase diagram around this point.
From that point of view, the identification of dimer phases in the context of spin-orbital
models of BaVS$_3$\cite{BaVS3} and of LiNiO$_2$\cite{vernay1} is
not unexpected, and the tendency to dimerize can be considered to be a generic
trend of spin-orbital models.

What seems to be more specific to these spin-orbital models of LiNiO$_2$
and BaVS$_3$ is the quasi-degeneracy of all nearest-neighbour dimer
coverings. But in fact, this can be traced back to a rather generic feature of
spin-orbital models, namely the remarkable symmetry properties of the orbital part
of the Hamiltonian. As can be clearly seen in the spin-orbital model of LiNiO$_2$, the orbital
part does not have the same form in the three directions of the triangular lattice,
a property encoded in the $\bf n_{ij}^z$ vectors. So the Hamiltonian is only
invariant if one simultaneously performs the same rotation in real space
and in pseudo-spin space. For purely orbital models, this is known to have
remarkable consequences\cite{nussinov,ma,doucot,dorier}. For spin-orbital
models, this implies that dimers with different orientations involve different
orbital wave-functions, as can be clearly seen in phases C and C'. What
controls the energy of a given dimer configuration is then the residual dimer-dimer
interaction.  It turns out  that simple patterns having
all dimers parallel to each other are not naturally favoured if the anisotropy of the orbital
part is strong because it is impossible to gain energy in the other directions.
On a lattice such as the triangular lattice with a large connectivity, it is then
much more
favourable to adopt configurations where dimers are not parallel to each other.
The energy difference between such configurations however is not really
significant, and it is better to look at such states as a variational basis.

Finally, too little is known at that stage about RVB phases in QDM to draw
general conclusions, but it seems plausible that the presence of an RVB phase
between two valence-bond phases is the generic alternative to a first order
transition.

To summarize, the tendency toward dimerization is a rather general feature
of spin-orbital models.
When confronted to a lattice such as the triangular lattice, for which
QDM's are known by now to possess RVB phases, there
is a real chance for quantum fluctuations to stabilize an RVB ground
state.

\section{Conclusion}

We have shown that orbital degeneracy can, under special but
neither unrealistic nor fine-tuned conditions, lead to a spin-orbital
RVB ground state. Clearly, this is not the most common situation.
Indeed, orbital degeneracy usually leads to a cooperative Jahn-Teller
transition, resulting into an effective spin Hamiltonian with a symmetry
different from that of the original lattice\cite{kugel}. This is not either the
only route to spin-orbital liquid behaviour\cite{loidl}.
However, the tendency of spin-orbital models to spontaneously dimerize
is strong enough to make this a promising route towards RVB physics.
Whether LiNiO$_2$ is the first example remains to be seen. To make progress
on this issue will require not only further theoretical work
to better understand the relevant microscopic model and its possible
connection to a QDM, but also and maybe more importantly
further experimental investigations to unambiguously identify
the orbital and magnetic properties of stoichiometric samples.

We acknowledge useful discussions with M. Ferrero and D. Ivanov.

        Label2.Text = "Button is clicked on id "+ id;
    }
    else

So what happens is when I click on the button, it doesn't ever reach this line:
(e.CommandName == "deletethis")

A: just for fun, try if (e.CommandName.ToLower().Equals("deletethis")).
i was just reading this sample - https://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.repeater.itemcommand(v=vs.110).aspx - and realized that a CommandName isn't even required for rep_ItemCommand to run. try running some code that doesn't check for the CommandName and see if it works. if it doesn't, it makes me wonder what's happening in OnItemDataBound="Repeater1_ItemDataBound".

Back for good, or bad
Feb 20th 2021 | words 774
When will most people be back at the office? As with Tantalus and the fruit tree, the prize seems to be close, only to recede out of reach. A survey conducted by Morgan Stanley, an investment bank, found that employees have adjusted their expectations for when they are likely to repopulate their desks, moving the date back from April to June. Given the slow pace of vaccinations in some countries, even that may be optimistic.
Companies have also had to adjust their expectations. Brian Kropp of Gartner, a research and advisory firm, says that businesses have gone through three phases. In the first, during the spring of 2020, they thought that the pandemic would be short-lived and that corporate life would soon return to normal. In the second, economic restrictions seemed set to last indefinitely and companies figured there was little point in planning for a post-pandemic world. In the third, current, stage the vaccines have brought hope of a reversion to normality, and businesses are trying to work out what the new world will look like.
Interestingly, Mr Kropp observes that views have switched since the start of the pandemic. A year ago, many executives were dubious that productivity could be maintained if employees worked from home. Staff, meanwhile, enjoyed the greater flexibility. Now managers are much more comfortable with the idea. But employees are hankering after the office, at least for part of the time.
This employee restlessness seems to relate to the sheer length of the lockdown. The novelty has worn off and working from home seems much less appealing in winter. And the time spent on screen has led to a feeling of fatigue.
It has also led to increased stress. A study of 1,500 workers in 46 countries by the Harvard Business Review found that 85% said their well-being had declined and 55% felt they had not been able to balance their work and home lives.
The problems are physical as well as mental. A survey of Italian workers found that 50% reported greater neck pain, and 38% increased lower-back pain, while working remotely. This is probably because home furniture is not designed to accommodate extensive computer use.
This does not mean that workers want to go back to the old days entirely. The Morgan Stanley survey found that employees said that, in future, they would like to work from home for two days a week, on average, compared with just one day a week before covid-19.
When people do come back, mask-wearing and social distancing will have to continue for a while. Even if they legally can, few employers will force their employees to get vaccinated, not least because of the furore this might arouse. Gartner surveyed 116 human-resources professionals and only 9% were planning to mandate vaccination. This may mean that 30-35% of American workers will not be vaccinated, Gartner says. They will be vulnerable to catching the virus at work.
Another problem for companies is that employees have become less loyal as the pandemic has progressed. Mr Kropp says that workers are spending more time looking for jobs online and updating their LinkedIn profiles. Since few businesses are hiring at the moment, not many employees have left. But when the economy opens up again, there might be a rush for the exit.
The urge to depart may not be universal. As Bartleby has argued before, the pandemic has divided workers into slackers and Stakhanovites. The first group are getting away with the minimum effort. The second are working even longer hours than before. It is the Stakhanovites who are more likely to leave, Mr Kropp argues, if they feel their efforts are not adequately rewarded.
All this presents challenges for managers who are planning a return to normal. They may have to redesign their offices to create more distance between desks, and come up with a system for allocating space to employees who may turn up for just three days a week. They need to recreate camaraderie within their teams and make sure their best employees do not head out the door.
Issues of equity may be trickiest of all to deal with. Women appear to be keener on working from home than men are. But Mr Kropp warns that managers have a tendency to reward those employees whom they can see, at the expense of those with whom they have reduced contact. That could widen the existing gender pay gap. In short, when the all-clear finally sounds, that may be just the start of managers problems.

The Cathedral symbol of the city
Top Art and Culture My first trip to Milano Children and families City centre
#churches
Piazza del Duomo
The construction of the Duomo di Milano initiated in 1386 on the site of the ancient basilicas of Santa Tecla and Santa Maria Maggiore, which were then demolished at a later date. Dedicated to Maria Nascente, the cathedral was commissioned by Gian Galeazzo Visconti and had a dual purpose: the plan was to replace the sites of worship in the heart of Milan with an imposing edifice and it was also intended to celebrate the Visconti Signoria and its ambitious expansion policy.
It is the largest and most complex Gothic building in Italy, made of pink-veined white marble from the Candoglia quarries, in the Val d'Ossola. It is 157 metres in length and covers an area of 11,700 m2. The highest spire measures 108.5 and, in October 1774, the golden 4,16 metre-high statue of the Madonna by the sculptor Giuseppe Perego was placed on its pinnacle.
The construction works were prolonged over five centuries and, during this extensive period, local and European architects, sculptors, artists and workers all proceeded in turn to work in the Fabbrica del Duomo. The result of all their labour is a unique style of architecture, a fusion of European Gothic style and Lombard tradition.
The abundance of adornment is impressive: spires, pinnacles and an immense patrimony of statues (approximately 3,400, of which 1,100 on the inside and 2,300 outside), plus, sculptures in the frames and windows and decorations on the facade.
The complexity of the build was such that the final part completed was the façade in 1813. Before this date the Santa Maria Maggiore façade was the provisional front of the cathedral.
The bronze doors date back to different periods in the twentieth century. The central door was carved with floral Gothic reliefs in 1906 by Ludovico Pogliaghi and the theme is "stories from the life of Mary".
The interior is shaped like a Latin cross and has large choir stalls and a polygonal apse. The style is mostly Late Gothic with the addition of classical elements from the Counter Reformation period when the presbytery, the main altar, the pulpit and some side altars were all created.
The crypt houses the chapel of S.Carlo Borromeo, designed by Francesco Maria Ricchino in 1606, with the rock crystal coffin which encloses the saint's body in pontifical dress.
The entire city of Milano can be admired from the rooftop terraces, which are accessed by lift or stairs.
DONT'MISS
A significant number of masterpieces are preserved inside the Duomo di Milano.
The funeral monument of Gian Giacomo Medici, known as Medeghino, brother of Pope Pius IV and uncle of Carlo Borromeo, is the work of Leone Leoni.
In the left transept, the splendid 'tree-shaped' Trivulziano candelabra, by the bronze sculptor Nicola da Verdun, was donated to the cathedral in 1562 by archpriest G.B. Trivulzio and dates from the end of the twelfth century.
The baptistery in the left aisle was added in the sixteenth century by Pellegrino Tibaldi in a classical temple; the precious central baptismal font carved in porphyry dates back to Roman times.
The area of archaeological excavations displays the remains of both the early Christian baptisteries of S. Giovanni alle Fonti and S.Stefano and the remains of the basilica of S. Tecla.
The windows of the cathedral, the oldest of which date back to the fifteenth century, represent a magnificent decorative cycle and were designed or created by artists such as Cristoforo de Mottis, Stefano da Pandino, Niccolò da Varallo and also Giuseppe Arcimboldo, Pellegrino Tibaldi and Giovanni Battista Bertini.
The tabernacle above the choir, illuminated by a red light, contains a nail allegedly from the cross of Jesus.
Over the centuries, the Milanese have donated generously to restore and maintain the upkeep of the Duomo. Donations can still be made today and are recorded in the Donors' register kept in the Fabbrica del Duomo.
The blocks of marble utilised for the construction of the cathedral arrived at the "laghetto" - a small reservoir located near the church of Santo Stefano - from Lake Maggiore by means of the Ticino, the Naviglio Grande and the internal trench of the Navigli.
In an attempt to avoid attracting the attention of the Allied bombers during the Second World War the Milanese covered the gilded surface of the statue of the Madonnina with rags.
An expression typically used in Lombard dialect, "a uf" (free, no charge) seems to be attributed in some way to the Duomo di Milano. In fact, according to tradition, it refers to the words "AUF - Ad Usum Fabricae" which, in all probability, permitted those who transported the blocks of marble for the cathedral to be exempt from paying duties. However, this tradition has not been confirmed by scholars who claim that "a uf" has an unknown etymology.
It is the first cathedral in the world to illuminate its windows from within so that, at night, the sacred images can be admired from the outside. Please visit www.duomomilano.it for advance dates of the special occasions, mainly related to major religious festivals, when the Duomo is illuminated.

2007 Home NewsroomPress releases2007CPF Changes and Workfare for Low Wage Workers
CPF Changes and Workfare for Low Wage Workers
16 February 2007 Employment practices
MOM restructures the CPF system and institutionalises Workfare to enable all Singaporeans to benefit from economic growth
With the economy doing well, it is timely to retune the balance of our CPF contribution rates towards the upper end of the 30-36% range. A modest CPF increase will not erode our economic competitiveness and will allow us to better meet the needs of an ageing population. To enable our workers to benefit from economic growth and to help them build up their CPF savings, effective 1 July 2007 the Government will raise the employer's CPF contribution rate by 1.5 percentage points.
2. This CPF increase will not apply for older low wage workers who are affected by wage stagnation and structural unemployment as a result of global competition. For this group, a different solution is required. Instead of raising their employer CPF contribution rates, we will instead reduce their CPF contributions: a reduction in employer CPF contributions to help improve their employability and a reduction in employee CPF contributions to increase their take-home pay. To complement these CPF changes, Government will implement a new Workfare Income Supplement Scheme (WIS) which will make up for the reductions in their CPF contributions.
3. The WIS and the 2007 CPF changes will provide more incentives for older low wage workers to work, and for employers to hire them.
Changes to CPF System
4. Effective 1 July 2007, the following changes will be made to the CPF system:
(i) Increase Employer CPF Contribution Rate by 1.5% Points
5. Workers earning more than $1,500 a month or who are 35 years or younger will have the full 1.5% point increase in the employer's CPF contribution rate. Workers above 35 years earning more than $1,200 will have partial increases, gradually stepped up to the 1.5% point increase at $1,500. 1 percentage point will go into the worker's Ordinary Account (OA) and 0.5 percentage point will go into the Medisave Account (MA). This will cost employers $600m more per year, an increase of 0.7% of the total wage bill or 0.3% of GDP. The CPF increases will help our ageing population build up their retirement adequacy. It will also help more workers pay for their mortgages and better provide for their healthcare needs. As a result, for a young worker earning $1,700 at age 211 , the 1.5% point increase in contribution rate will increase his CPF balances at age 55 by a projected $17,900 or 12% over his lifetime. For an older worker aged 45 years and earning $3,000, it will increase his CPF balances at age 55 by a projected $6,000 or 6%.
(ii) Increase Take-Home Pay of Low-Wage Workers by Lowering Employee CPF Contribution
6. Workers who earn $1,500 or less per month will now pay less than full rates for their employee CPF contributions applicable to their age group. By reducing the employee CPF contribution rates for low wage workers who earn between $500 and $1,500 per month, we will increase their take-home pay. Please refer to Table 1 at Annex A.
(iii) Increase Employability of Older Low-Wage Workers by Lowering Employer CPF Contribution
7. Employers will now pay less than full rates in employer CPF contributions for older workers who earn $1,500 or less per month. By lowering the employer CPF contribution rates, we lower wage costs and improve the employability of older, low wage workers. Please refer to Table 2 at Annex A.
Changes to Workfare
(i) New Workfare Income Supplement Scheme for Older Low-Wage Workers
8. The CPF contributions for low wage workers will be reduced as a result of the reductions to their employee and employer contribution rates. The government will in tandem give this group Workfare income supplements, mainly into their CPF accounts, and so help them to build up their savings for future needs. The WIS payouts will, in general, more than offset the reduction in CPF contributions for older, low wage workers.
9. The principal target group of low wage workers comprise older, full time workers aged above 45 years who earn $1,000 or less. They will receive the highest WIS benefits, up to a maximum annual payout of $1,200. However, we will extend the WIS benefits to a wider group – to those above 35 years who earn $1,500 or less - but at a lower rate.
10. The WIS quantum will depend on age with the lower income and older workers getting more (please refer to Table 4 at Annex B). It will be paid out in a cash-to-CPF ratio of 1 : 2.5. A larger proportion will be paid into the CPF to help low wage workers better provide for their future needs.
11. The WIS is conditional on regular work and will be paid out twice a year. To qualify, beneficiaries must:
Be a Singapore Citizen; and
Have a monthly salary of $1,500 or less; and
Be above 35 years of age; and
Stay in a property with an Annual Value of not more than $10,000; and
Have worked at least three months in any six month period in the calendar year for half the payout, or at least six months in the calendar year for the full payout.
12. In addition, contributions to CPF will be a prerequisite for receiving WIS benefits. The WIS will be administered through the CPF system to ensure proper verification of work and income
(ii) WIS for Self-Employed Persons
13. Low wage self-employed persons (SEPs) will be required to contribute into their Medisave Accounts (MA) in order to receive WIS. This is because they need to build up their MA to provide for their future healthcare needs. Like formal employees, the principle of co-contribution into their CPF will apply. To encourage low-income self-employed persons to contribute to Medisave, we will reduce their contribution rate to one-third of the full Medisave rates. Please refer to Table 3 in Annex A for details on the changes to the SEP contribution rates. Those who qualify for Workfare will receive from the Government two-thirds the amount of the WIS for employees. Please refer to Table 5 in Annex B for details on the WIS benefits for the self-employed. This will be paid into their Medisave.
(iii) WIS for Informal Workers
14. Informal workers will also receive the same WIS benefits as self-employed persons, if they work and contribute to their Medisave like self-employed persons. We want to bring as many informal workers as possible into the CPF system so that they can build up savings for their future needs. Under the CPF Act, so long as a worker works regularly for any employer, that employer is liable to pay their CPF. As we institutionalise Workfare, MOM and CFB will step up enforcement to ensure that payment for CPF is complied with. Apart from Medisave contributions, self-employed persons and informal workers will also have to declare to the CPF Board that they are working.
Overall Impact of the WIS and CPF Changes
15. The WIS is expected to benefit 438,000 Singaporeans2, and cost about $400m per year. The numbers are likely to go up over time as more individuals are incentivised to join the workforce and contribute to CPF. We will review the WIS Scheme after three years and adjust it to better achieve our objectives. Older low wage workers will benefit from these changes to increase their take-home pay, make them more employable to employers and help build up their CPF savings. For an illustration of the impact of WIS and CPF changes on older, low wage workers, please refer to Examples 6.1-6.4 at Annex C.
The following lists how age and income boundaries are defined in the Annexes.
Above 35 years – 45 years:
A person who is at least one day past his 35th birthday (i.e. 35 years old + 1 day up to the person's 45th birthday
50 years or less:
A person at his 50th birthday or has yet to reach his 50th birthday.
Above 45 years:
A person who is at least one day past his 45th birthday (i.e. 45 years old + 1 day)
< $500:
Exactly $500 or less.
> $500 - $1,500:
From $500.01 up to exactly $1,500.
More than $1,500:
From $1,500.01 and above.
Net Trade Income:
"Net trade income" is your gross trade income minus all allowable business expenses, capital allowances and trade losses as determined by the Inland Revenue Authority of Singapore (IRAS). It excludes income from share dividends, employment and interest from savings.
1 Based on the Labour Force Survey, the median income of full time employed residents is $2,170.
2 Estimated numbers by imposing the Housing AV criterion.

Hi, I would like to configure Grandstream GXV3615WI_HD IP Camera on Dahua NVR. I installed GSurf Pro V2. In search option I have tried to find my IP camera, but it don't work!
Any better suggestion or link please!
This may be a question that is better submitted to Dahua. The camera you list is obsolete and has not been on the market for some time now. I still have one in use in my office.
In any event, the first thing is to get the manual and read it as it will inform that you need to hook up the camera to a wired connection and then informs on how to connect. As you have not indicated if you intend to use it with a wired or Wi-Fi connection nor the model of recorder, this is about as far as I can suggest at the moment.
Following is a link to the resources associated to the camera and you will find the manual as well as some references of how to hook up using other makes of NVRs which may give enough of a clue to assist with your needs.
Going to download all documents, let's see what will happen!


These cachepots are designed for those who find ordinary plastic pots unattractive. Ornately hand-painted with birds, dragon, orchids, and various exotic flowers and pattens, these pots are pure beauty. In ancient China, such midsize porcelain containers were used in wintertime to house small carps brought inside from the ponds surrounding the homes of the aristocracy. Today, they are prized for their exotic look and intricate design. Our versions are decorated inside and out with exotic colors of magenta, sky blue, green, gold, and peruvian yellow. An excellent gift by itself or with potted orchids, some these cachepots are presented on a carved high-leg stand - view pots to shop. Imported.

Aleph es el álbum debut del músico y productor francés Gesaffelstein, lanzado el 28 de octubre de 2013 en Parlophone y a través de OWSLA en Norteamérica. Gesaffelstein comenzó a grabarlo en 2011, y mientras seguía trabajando en ello, ganó popularidad como uno de los productores detrás de Yeezus (2013) de Kanye West. Se lanzaron dos singles para promocionar a Aleph: "Pursuit" y "Hate or Glory". El álbum recibió críticas positivas por parte de los críticos de música.

Promoción y lanzamiento
Antes del lanzamiento de Aleph, se lanzaron dos singles para promocionar el álbum. El primero, "Pursuit", fue lanzado el 17 de junio de 2013. El mismo día también se lanzó un vídeo musical. Spin lo nombró uno de los mejores vídeos musicales de 2013. El segundo sencillo, "Hate or Glory", fue lanzado el 8 de octubre de 2013, junto con un vídeo musical para el mismo.

En septiembre de 2013, el álbum estuvo disponible para pre-ordenar. También se mostró el empaque del álbum. Al igual que Yeezus de Kanye West, el lanzamiento físico no incluye la portada del álbum. Solo se muestra un disco de oro como carátula frontal del álbum y que está dentro de un estuche de cristal de CD vacío, cubierto por delgadas líneas blancas, que se asemejan a una placa de circuito, con una letra blanca hebrea aleph en el medio. Aleph fue lanzado el 28 de octubre de 2013 en Parlophone y a través de OWSLA en América del Norte.

Recepción de la crítica
Aleph recibió la aclamación generalizada de los críticos. Escribiendo para Pitchfork, Jamieson Cox elogió el álbum y lo comparó con Yeezus de Kanye West en términos de su "consistencia temática y coherencia", al tiempo que calificó la falta de concisión del álbum como su principal debilidad.  Derek Staples, de Consequence of Sound, destacó el "firme enfoque del álbum en infundir el caos en la pista de baile con melodías silenciosas, voces penetrantes y líneas de bajo aisladas y mínimas" y afirmó que Gesaffelstein estaba "fortaleciendo las raíces de una carrera muy exitosa".

David Renshaw, de la revista NME, consideró que gran parte del álbum tenía "una frialdad de acero inoxidable", que afirmó "en su mayoría funciona". En Los Angeles Times, August Brown llamó revolucionario al álbum de Gesaffelstein y "una reacción dura a los tonos de discoteca suavizados que han dominado los clubes de radio y mainstream en los últimos tiempos ". Reef Younis en su crítica para la revista Clash le dio al álbum un 8/10 y escribió: "Desde el beat de tom-tom del intro de 'Out Of Line' hasta el electro retorcido de 'Trans', los ritmos golpearon con un estruendo mecánico. "

Elogios
Spin presentó a Aleph en su lista de los "20 mejores álbumes de baile de 2013", diciendo que Gesaffelstein "trae toda la amenaza de Ministry a finales de los 80 y crea una paliza texturalmente desnuda de ruidos oxidados y basura digital". Complex lo nombró uno de los mejores álbumes de EDM de 2013, diciendo que el álbum "nos lleva de vuelta a la última era de la electrónica, donde las principales discográficas estaban buscando discos que superaran los límites" y que Gesaffelstein "mantiene un ambiente crudo y agresivo , pero no tiene miedo de ir directamente a lo turbio ". Billboard colocó el álbum en el posición n.º 14 en su lista de los 20 mejores álbumes de música de baile de 2013, afirmando que "el debut completo de Lévy implica un nihilismo casi refrescante que rechaza la luz del sol y la luz del EDM en un lenguaje sonoro que aún entiende".

Tracklist del álbum
Todas las pistas están escritas por Mike Lévy

Notas

 La versión en CD contiene una pista oculta titulada "Premiere Porte" en la pista 14 "Perfection". Premiere Porte comienza a partir del minuto 8:30 aproximadamente. Por eso Perfection se ejecuta durante 12 minutos y 17 segundos (12:17) en la versión CD de Aleph.
