Magnetoelastic coupling enabled tunability of magnon spin current generation in 2D antiferromagnets
Nasim Bazazzadeh, Mohammad Hamdi, Sungjoon Park +3
We theoretically investigate the magnetoelastic coupling (MEC) and its effect on magnon transport in two-dimensional antiferromagnets with a honeycomb lattice. MEC coeffcient along…
Thermal Hall effect from two-dimensional Schwinger-boson gas with Rashba spin-orbit interaction: application to ferromagnets with in-plane Dzyaloshinskii-Moriya interaction
Sungjoon Park, Bohm-Jung Yang
Recently, uncovering the sources of thermal Hall effect in insulators has become an important issue. In the case of ferromagnetic insulators, it is well known that Dzyaloshinskii-M…
Phonon angular momentum Hall effect
Sungjoon Park, Bohm-Jung Yang
Spin Hall effect is the transverse flow of the electron spin in conductors under external electric field. Similarly, thermal gradient in magnetic insulators can drive a transverse…
Thermal Hall effect, spin Nernst effect, and spin density induced by thermal gradient in collinear ferrimagnets from magnon-phonon interaction
Sungjoon Park, Naoto Nagaosa, Bohm-Jung Yang
We theoretically study the intrinsic thermal Hall and spin Nernst effect in collinear ferrimagnets on a honeycomb lattice with broken inversion symmetry. The broken inversion symme…
Stiefel-Whitney classes and topological phases in band theory
Junyeong Ahn, Sungjoon Park, Dongwook Kim +2
In this article, we review the recent progress in the study of topological phases in systems with space-time inversion symmetry . is an anti-unitary…
Topological Magnetoelastic Excitations in Non-Collinear Antiferromagnets
Sungjoon Park, Bohm-Jung Yang
We study the topological property of the magnetoelastic excitation in non-collinear antiferromagnets. As a toy model, we consider the magnon-phonon coupling in a triangular antifer…
