In the recent years, the thermal Hall transport has risen as an important diagnosis of the
physical properties of the elementary excitations in various quantum materials, especially …

Because electrons and ions form a coupled system, it is a priori clear that the dynamics of
the lattice should reflect symmetry breaking within the electronic degrees of freedom …

We present computations of the thermal Hall coefficient of phonons scattering off a defect
with multiple energy levels. Using a microscopic formulation based on the Kubo formula, we …

From a systematic study of thermal and charge transport in various single crystals of
compensated topological insulators we identify the evolution of a large low-temperature …

We study the spin-1/2 Heisenberg model on the square lattice with the first-and second-
nearest-neighbor antiferromagnetic couplings J 1 and J 2, as well as the three-spin scalar …

Two-dimensional Heisenberg honeycomb ferromagnets are expected to have interesting
topological magnon effects, as their magnon dispersion can have Dirac points. The Dirac …

Thermal Hall effect (THE) in insulator is a remarkable phenomenon that arises from the
motion of chargeless quasi-particles under a magnetic field. While magnons or exotic spin …

We systematically derive the quantum kinetic equation in full phase space for any quadratic
Hamiltonian of bosonic fields, including in the absence of translational invariance. This …

Spin-phonon coupling underlies a number of diverse range of phenomena of recent interest,
particularly in transition metal insulators with strong spin-orbit effects, where it may give rise …

We present a theory of magnonic thermal Hall transport driven by many-body skew
scattering. In field-polarized chiral magnets, the Dzyaloshinskii-Moriya interaction induces …
