Nonreciprocal phonon dichroism induced by Fermi pocket anisotropy in two-dimensional Dirac materials
Wen-Yu Shan
Electrons in two-dimensional (2D) Dirac materials carry local band geometric quantities, such as the Berry curvature and orbital magnetic moments, which, combined with electron-pho…
Magneto-optical Kerr and Faraday effects in bilayer antiferromagnetic insulators
Wan-Qing Zhu, Wen-Yu Shan
Control and detection of antiferromagnetic topological materials are challenging since the total magnetization vanishes. Here we investigate the magneto-optical Kerr and Faraday ef…
Anomalous circular phonon dichroism in transition metal dichalcogenides
Wen-Yu Shan
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 dichr…
Impact of novel electron-phonon coupling mechanisms on valley physics in two-dimensional materials
Wen-Yu Shan
We systematically study the impact of various electron-acoustic-phonon coupling mechanisms on valley physics in two-dimensional materials. In the static strain limit, we find that…
Strain-Fluctuation-Induced Near-Quantization of Valley Hall Conductivity in Graphene Systems
Wen-Yu Shan, Di Xiao
We develop a theory of the valley Hall effect in high-quality graphene samples, in which strain fluctuation-induced random gauge potentials have been suggested as the dominant sour…
Optical Selection Rule of Excitons in Gapped Chiral Fermion Systems
Xiaoou Zhang, Wen-Yu Shan, Di Xiao
We show that the exciton optical selection rule in gapped chiral fermion systems is governed by their winding number , a topological quantity of the Bloch bands. Specifically, i…
