Edge states in a non-Hermitian topological crystalline insulator
Qiu-Yue Xu, Feng Liu, Chui-Zhen Chen +1
Breaking Hermiticity in topological systems gives rise to intriguing phenomena, such as the exceptional topology and the non-Hermitian skin effect. In this work, we study a non-Her…
Coexisting of Quantum Hall and Quantum Anomalous Hall phases in Disordered
Hailong Li, Chui-Zhen Chen, Hua Jiang +1
In most cases, to observe quantized Hall plateaux, an external magnetic field is applied in intrinsic magnetic topological insulators . Nevertheless, whether t…
Bulk-boundary correspondence in disordered higher-order topological insulators
Yu-Song Hu, Yue-Ran Ding, Jie Zhang +2
In this work, we study the disorder effects on the bulk-boundary correspondence of two-dimensional higher-order topological insulators (HOTIs). We concentrate on two cases: (i) bul…
Direct visualization of edge state in even-layer MnBi2Te4 at zero magnetic field
Weiyan Lin, Yang Feng, Yongchao Wang +12
Being the first intrinsic antiferromagnetic(AFM) topological insulator(TI), MnBi2Te4 is argued to be a topological axion state in its even-layer form due to the antiparallel magnet…
Evolution of Berry curvature and reentrant quantum anomalous Hall effect in an intrinsic magnetic topological insulator
Chui-Zhen Chen, Junjie Qi, Dong-Hui Xu +1
Recently, the magnetic topological insulator MnBiTe emerged as a competitive platform to realize quantum anomalous Hall (QAH) states. We report a Berry-curvature splitting…
The Global Phase Diagram of disordered Higher-order Weyl Semimetals
Zhi-Qiang Zhang, Bing-Lan Wu, Chui-Zhen Chen +1
We study the disorder-induced phase transition of higher-order Weyl semimetals (HOWSMs) and the fate of the topological features of disordered HOWSMs. We obtain a global phase diag…
