Copropagating edge states produced by the interaction between electrons and chiral phonons in two-dimensional materials

J Medina Dueñas, HL Calvo, LEF Foa Torres - Physical Review Letters, 2022 - APS
Unlike the chirality of electrons, the intrinsic chirality of phonons has only surfaced in recent
years. Here, we report on the effects of the interaction between electrons and chiral phonons …

Magneto-optical Kerr spectra of gold induced by spin accumulation

VH Ortiz, S Coh, RB Wilson - Physical Review B, 2022 - APS
We report the magneto-optic Kerr effect (MOKE) angle of Au magnetically excited by spin
accumulation. We perform time-resolved polar MOKE measurements on Au/Co …

Strain-driven chiral phonons in two-dimensional hexagonal materials

H Rostami, F Guinea, E Cappelluti - Physical Review B, 2022 - APS
Hexagonal two-dimensional materials with broken inversion symmetry (as BN or transition
metal dichalcogenides) are known to sustain chiral phonons with finite angular momentum …

Interband chiral phonon transfer in a magnetic field

G **ong, Z Yu, L Zhang - Physical Review B, 2022 - APS
Chiral phonons, which offer a possibility for information processing and storing, have been
theoretically proposed and experimentally observed in two-dimensional hexagonal lattices …

Electrically controllable chiral phonons in ferroelectric materials

H Chen, W Wu, K Sun, SA Yang, L Zhang - Applied Physics Letters, 2024 - pubs.aip.org
Chiral phonons have attracted increasing attention, as they play important roles in many
different systems and processes. However, a method to control phonon chirality by external …

Gate-tunable circular phonon dichroism effect in bilayer graphene

WY Shan - Iscience, 2024 - cell.com
Circular phonon dichroism effect has been proposed in two-dimensional materials; however,
the lack of tunability hinders the exploration of the effect. Here, we investigate the role of …

Anomalous circular phonon dichroism in transition metal dichalcogenides

WY Shan - Physical Review B, 2022 - APS
A magnetic field can generally induce circular phonon dichroism based on the formation of
Landau levels of electrons. Here, we study the magnetization-induced circular phonon …

Electric field control of phonon angular momentum in perovskite

K Moseni, RB Wilson, S Coh - Physical Review Materials, 2022 - APS
We find that in BaTiO 3 the phonon angular momentum is dominantly pointing in directions
perpendicular to the electrical polarization. Therefore, the external electric field in …

Phonon dichroism in proximitized graphene

WY Shan - Chinese Physics B, 2023 - iopscience.iop.org
We systematically investigate the phonon dichroism in proximitized graphene with broken
time-reversal symmetry. We find that in the absence of any type of spin–orbit coupling …
