Disorder-Induced Phase Transitions in Three-Dimensional Chiral Second-Order Topological Insulator
Yedi Shen, Zeyu Li, Qian Niu +1
Topological insulators have been extended to higher-order versions that possess topological hinge or corner states in lower dimensions. However, their robustness against disorder i…
Berry-Curvature Engineering for Nonreciprocal Directional Dichroism in Two-Dimensional Antiferromagnets
Wenhao Liang, Junjie Zeng, Zhenhua Qiao +2
In two-dimensional antiferromagnets, we identify the mixed Berry curvature as the geometrical origin of the nonreciprocal directional dichroism (NDD), which refers to the differenc…
Non-Hermitian bulk-boundary correspondence via scattering theory
Haoshu Li, Qian Niu
The conventional bulk-boundary correspondence breaks down in non-Hermitian systems. In this paper, we reestablish the bulk-boundary correspondence in one-dimensional non-Hermitian…
Time-Reversal-Even Nonlinear Current Induced Spin Polarization
Cong Xiao, Weikang Wu, Hui Wang +6
We propose a time-reversal-even spin generation in second order of electric fields, which dominates the current induced spin polarization in a wide class of centrosymmetric nonmagn…
Semiclassical dynamics of electrons in space-time crystal: Magnetization, polarization, and current response
Qiang Gao, Qian Niu
A space-time crystal is defined as a quantum mechanical system with both spatial and temporal periodicity. Such a system can be described by the Floquet-Bloch (FB) theory. We first…
Transport theory for topological Josephson junctions with a Majorana qubit
Zhi Wang, Jia-Jin Feng, Zhao Huang +1
We construct a semiclassical theory for the transport of topological junctions starting from a microscopic Hamiltonian that comprehensively includes the interplay among the Majoran…
