Electric field controlled valley-polarized photocurrent switch based on the circular bulk photovoltaic effect
Yaqing Yang, Xiaoyu Cheng, Liantuan Xiao +4
Efficient electric manipulation of valley degrees of freedom is critical and challenging for the advancement of valley-based information science and technology. We put forth an ele…
Topological photonic alloy
Tiantao Qu, Mudi Wang, Xiaoyu Cheng +6
We present the new concept of photonic alloy as a non-periodic topological material. By mixing non-magnetized and magnetized rods in a non-periodic 2D photonic crystal configuratio…
Quantum nonlinear ac transport theory at low frequency
Lei Zhang, Fuming Xu, Jian Chen +2
Based on the nonequilibrium Green's function (NEGF), we develop a quantum nonlinear theory to study time-dependent ac transport properties in the low frequency and nonlinear bias v…
Unified framework of the microscopic Landau-Lifshitz-Gilbert equation and its application to Skyrmion dynamics
Fuming Xu, Gaoyang Li, Jian Chen +4
The Landau-Lifshitz-Gilbert (LLG) equation is widely used to describe magnetization dynamics. We develop a unified framework of the microscopic LLG equation based on the nonequilib…
Topological Anderson amorphous insulator
Xiaoyu Cheng, Tiantao Qu, Liantuan Xiao +3
The topological phase in amorphous systems adds a new dimension to the topological states of matter. Here, we present an interesting phenomenon dubbed the topological Anderson amor…
Photogalvanic effect induced charge and spin photocurrent in group-V monolayer systems
Li-Wen Zhang, Ya-Qing Yang, Jun Chen +1
Photogalvanic effect (PGE) occurs in materials with non-centrosymmetric structures when irradiated by linearly or circularly polarized light. Here, using non-equilibrium Green's fu…
