Disorder-Induced Quantum Phase Transitions in Three-Dimensional Second-Order Topological Insulators
C. Wang, X. R. Wang
Disorder effects on three-dimensional second-order topological insulators (3DSOTIs) are investigated numerically and analytically. The study is based on a tight-binding Hamiltonian…
Level statistics of extended states in random non-Hermitian Hamiltonians
C. Wang, X. R. Wang
Absence of level repulsion between extended states in random non-Hermitian systems is demonstrated. As a result, the general Wigner-Dyson distributions of level spacing of diffusiv…
Unusual Metal to Marginal-Metal Transition in Two-Dimensional Ferromagnetic Electron Gases
Weiwei Chen, C. Wang, Qinwei Shi +2
Two-dimensional ferromagnetic electron gases subject to random scalar potentials and Rashba spin-orbit interactions exhibit a striking quantum criticality. As disorder strength …
Non-Quantized Edge Channel Conductance and Zero Conductance Fluctuation in Non-Hermitian Chern Insulators
C. Wang, X. R. Wang
The quantized conductance plateaus and zero conductance fluctuation are the general consequence of electron transport in chiral edge states of Hermitian Chern insulators. Here we s…
Current-induced skyrmion motion on magnetic nanotubes
Xiaofan Wang, X. S. Wang, C. Wang +3
Magnetic skyrmions are believed to be the promising candidate of information carriers in spintronics. However, the skyrmion Hall effect due to the nontrivial topology of skyrmions…
Edge states in a two-dimensional honeycomb lattice of massive magnetic skyrmions
Z. -X. Li, C. Wang, Yunshan Cao +1
We study the collective dynamics of a two-dimensional honeycomb lattice of magnetic skyrmions. By performing large-scale micromagnetic simulations, we find multiple chiral and non-…
