The form of energy termed heat that typically derives from lattice vibrations, ie, phonons, is
usually considered as waste energy and, moreover, deleterious to information processing …

The spin Seebeck effect refers to the generation of a spin voltage caused by a temperature
gradient in a ferromagnet, which enables the thermal injection of spin currents from the …

In monolayer hexagonal lattices, the intravalley and intervalley scattering of electrons can
involve chiral phonons at Brillouin-zone center and corners, respectively. At these high …

The Hall effect usually occurs in conductors when the Lorentz force acts on a charge current
in the presence of a perpendicular magnetic field. Neutral quasi-particles such as phonons …

Pursuing topological phases in natural and artificial materials is one of the central topics in
modern physical science and engineering. In classical magnetic systems, spin waves (or …

The origin of phonon thermal Hall Effect (THE) observed in a variety of insulators is yet to be
identified. Here, we report on the observation of a thermal Hall conductivity in a non …

We provide a topological understanding of the phonon Hall effect in dielectrics with Raman
spin-phonon coupling. A general expression for phonon Hall conductivity is obtained in …

It has been known for more than a decade that phonons can produce an off-diagonal
thermal conductivity in the presence of a magnetic field. Recent studies of thermal Hall …

We study the angular momentum of phonons in a magnetic crystal. In the presence of a spin-
phonon interaction, we obtain a nonzero angular momentum of phonons, which is an odd …

We propose a new mechanism for the thermal Hall effect in exchange spin-wave systems,
which is induced by the magnon-phonon interaction. Using symmetry arguments, we first …
