We review the interplay of frustration and strong electronic correlations in quasi-two-
dimensional organic charge transfer salts, such as (BEDT-TTF) 2 X and Et n Me 4− n Pn [Pd …

We review recent developments in the research of nonlinear and nonequilibrium
phenomena in solids focusing on their geometrical aspects. We start with introducing the …

We present a theory of the thermal Hall effect in insulating quantum magnets, where the heat
current is totally carried by charge-neutral objects such as magnons and spinons. Two …

The search for quantum spin liquids in frustrated quantum magnets recently has enjoyed a
surge of interest, with various candidate materials under intense scrutiny. However, an …

We investigate the J 1-J 2 Heisenberg model on the triangular lattice with an additional
scalar chirality term and show that a chiral spin liquid is stabilized in a sizable region of the …

We consider orbital magnetic field effects in a spin liquid phase of a half-filled triangular
lattice Hubbard system close to the Mott transition, continuing an earlier exploration of a …

We study the spin-1/2 Heisenberg model on the triangular lattice with the nearest-neighbor J
1> 0, the next-nearest-neighobr J 2> 0 Heisenberg interactions, and the additional scalar …

Scalar spin chirality, a three-body spin correlation that breaks time-reversal symmetry, is
revealed to couple directly to circularly polarized laser. This is shown by the Floquet …

Motivated by recent transport measurements in high-T c cuprate superconductors in a
magnetic field, we study the thermal Hall conductivity in materials with topological order …

Common wisdom about conventional antiferromagnets is that their low-energy physics is
governed by spin–wave excitations. However, recent experiments on several cuprate …
