Thermal Hall Effect of Chiral Spin Fluctuations
Caitlin Carnahan, Yinhan Zhang, Di Xiao
Using a two-dimensional square lattice Heisenberg model with a Rashba-type Dzyaloshinskii-Moriya interaction, we demonstrate that chiral spin fluctuations can give rise to a therma…
Thermodynamics of Energy Magnetization
Yinhan Zhang, Yang Gao, Di Xiao
We construct the thermodynamics of energy magnetization in the presence of gravitomagnetic field. We show that the free energy must be modified to account for the modification of t…
Tunable Layer Circular Photogalvanic Effect in Twisted Bilayers
Yang Gao, Yinhan Zhang, Di Xiao
We develop a general theory of the layer circular photogalvanic effect (LCPGE) in quasi two-dimensional chiral bilayers, which refers to the appearance of a polarization-dependent,…
Topological charge pumping in twisted bilayer graphene
Yinhan Zhang, Yang Gao, Di Xiao
We show that a sliding motion between the two layers of a \moire superlattice induces an electric current and realizes a two-dimensional version of the topological Thouless pump wh…
Density Functional Theory of Composite Fermions
Yinhan Zhang, Junren Shi
We construct a density functional theory for two-dimension electron (hole) gases subjected to both strong magnetic fields and external potentials. In particular, we are focused on…
Thermal Hall Effect Induced by Magnon-Phonon Interactions
Xiaoou Zhang, Yinhan Zhang, Satoshi Okamoto +1
We propose a new mechanism for the thermal Hall effect in exchange spin-wave systems, which is induced by the magnon-phonon interaction. Using symmetry arguments, we first show tha…
