With the appearance of energy crisis, greenhouse effect, and heat management problem,
the control especially the active and reversible control of heat transport or thermal …

We study magnon-polaron hybrid states, mediated by Dzyaloshinskii-Moriya and
magnetoelastic interactions, in a two-dimensional ferromagnetic insulator. The magnetic …

We report an in-plane thermal transport study of the honeycomb Kitaev material Na 2 Co 2
TeO 6 at sub-Kelvin temperatures. In zero magnetic field, the κ (T) displays a rather weak T …

The thermal Hall effect in magnetic insulators has been considered a powerful method for
examining the topological nature of charge-neutral quasiparticles such as magnons. Yet …

Co-based materials have recently been explored because of their potential to realize
complex bond-dependent anisotropic magnetism. Prominent examples include Na 2 Co 2 …

Chiral phonons composed of circular atomic motion possess a tiny magnetic moment as a
result of the small g factor of ions. The couplings with the spin and orbit of electrons could …

The quest for a half-quantized thermal Hall effect of a Kitaev system represents an important
tool to probe topological edge currents of emergent Majorana fermions. Pertinent …

Topology plays a crucial and multifaceted role in solid state physics, leading to a remarkable
array of newly investigated materials and phenomena. In this Perspective, we provide a brief …

Kitaev interactions, arising from the interplay of frustration and bond anisotropy, can lead to
strong quantum fluctuations and, in an ideal case, to a quantum-spin-liquid state. However …

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 …
