Title:
Valence-bond and gapless liquid states in triangular lattice SU(4) antiferromagnets
Abstract:
In systems with many local degrees of freedom, high-symmetry points in the phase diagram can provide an important starting point for the investigation of the broader phase diagram. In systems with both spin and orbital (or valley) degrees of freedom, SU(4)-symmetric models can serve as such a starting point.

The roles of structural, magnetic and electronic degrees of freedom in Mott insulator-metal
transitions
The insulator-metal transition (IMT) in Mott insulators generally involves changes in structural,
magnetic and electronic degrees of freedom. Disentangling their contributions is of critical
importance for understanding their roles in the IMT and developing novel functionalities. We
show that in the archetypal Mott insulator V 2 O 3 , the structural and electronic degrees of

Nanoscale imaging of quantum Hall edge currents in single layer graphene and in
magic angle twisted bilayer graphene
Aviram Uri, Weizmann Institute of Science
The recently predicted topological magnetoelectric effect [1] is a fundamental attribute of topological
states of matter with broken time reversal symmetry, and is the underlying mechanism of the quantum
Hall effect. Using a scanning SQUID-on-tip [2], acting as an ultrasensitive nanoscale magnetometer, we

Emptiness Formation Probability and the Painleve` V equation

Abstract: The Emptiness Formation Probability is the probability of finding L consecutive down spins in the ground state of a spin 1/2 chain.
It represents perhaps the simplest correlator that can be calculated in a quantum spin chain. I will discuss this quantity in the XY spin chain, including the best-known example of the Ising spin chain in transverse field. It is shown, in particular,  that in the scaling limit, the Emptiness Formation Probability is the tau-function of a Painleve` V equation.
