Chiral Hinge Transport in Disordered Non-Hermitian Second-Order Topological Insulators
C. Wang, X. R. Wang
The generalized bulk-boundary correspondence predicts the existence of the chiral hinge states in three-dimensional second-order topological insulators (3DSOTIs), resulting in a qu…
Hermitian chiral boundary states in non-Hermitian topological insulators
C. Wang, X. R. Wang
Eigenenergies of a non-Hermitian system without parity-time symmetry are complex in general. Here, we show that the chiral boundary states of higher-dimensional (two-dimensional an…
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-…
Antiferromagnetism emerging in a ferromagnet with gain
Huanhuan Yang, C. Wang, Tianlin Yu +2
We present a theoretical mapping to show that a ferromagnet with gain (loss) is equivalent to an antiferromagnet with an equal amount of loss (gain). Our finding indicates a novel…
Interplay of Wave Localization and Turbulence in Spin Seebeck Effect
C. Wang, Yunshan Cao, X. R. Wang +1
One of the most important discoveries in spintronics is the spin Seebeck effect (SSE) recently observed in both insulating and (semi-)conducting magnets. However, the very existenc…
Twisted skyrmion at domain boundaries and the method of image
Huanhuan Yang, C. Wang, Xiaofan Wang +3
We predict a novel twisted skyrmion structure at the boundary of two antiferromagnetically coupled magnetic domains with antiparallel magnetization directions. Through this interme…
