Probing topology in nonlinear topological materials using numerical -theory

S Wong, TA Loring, A Cerjan - Physical Review B, 2023 - APS
Nonlinear topological insulators have garnered substantial recent attention as they have
both enabled the discovery of new physics due to interparticle interactions, and may have …

Intrinsic nonlinear thermal Hall transport of magnons: A quantum kinetic theory approach

H Varshney, R Mukherjee, A Kundu, A Agarwal - Physical Review B, 2023 - APS
We present a systematic study of the nonlinear thermal Hall responses in bosonic systems
using the quantum kinetic theory framework. We demonstrate the existence of an intrinsic …

Interaction-induced nonlinear magnon transport in noncentrosymmetric ferromagnets

K Fujiwara, T Morimoto - arXiv preprint arXiv:2404.03260, 2024 - arxiv.org
We study the effect of the magnon-magnon interaction on the nonlinear magnon transport.
The magnon-magnon interaction induces nonreciprocal magnon decay when the time …

Magnon Nonlinear Hall Effect in 2D Antiferromagnetic Insulators

J Ni, Y Jin, G Chang - arXiv preprint arXiv:2410.10355, 2024 - arxiv.org
Exploring antiferromagnetic (AFM) insulators has long been challenging due to their zero
spontaneous magnetization and stable insulating state, with this challenge being even more …

Intrinsic second-order magnon thermal Hall effect

JC Li, ZG Zhu - Journal of Physics: Condensed Matter, 2024 - iopscience.iop.org
In this paper, we study the intrinsic contribution of nonlinear magnon thermal Hall Effect. We
derive the intrinsic second-order thermal Hall conductivity of magnon by the thermal scalar …
