Chern Vector Protected Three-dimensional Quantized Hall Effect
Zhi-Qiang Zhang, Shu-Guang Cheng, Hongfang Liu +3
Recently, Chern vector with arbitrary formula in three-dimensional systems has been experimentally realized [\…
Three-dimensional quantum anomalous Hall effect in Weyl semimetals
Zhi-Qiang Zhang, Yu-Hang Li, Ming Lu +4
The quantum anomalous Hall effect (QAHE) is a quantum phenomenon in which a two-dimensional system exhibits a quantized Hall resistance in the absence of magnetic field, wh…
Measurement of the Chern Number for Non-Hermitian Chern Insulators
Hongfang Liu, Ming Lu, Shengdu Chai +2
The identification of the topological invariant of a topological system is crucial in experiments. However, due to the inherent non-Hermitian features, such determination is notabl…
Modified Generalized-Brillouin-Zone Theory with On-site Disorders
Hongfang Liu, Ming Lu, Zhi-Qiang Zhang +1
We study the characterization of the non-Hermitian skin effect (NHSE) in non-Hermitian systems with on-site disorder. We extend the application of generalized-Brillouin-zone (GBZ)…
Bulk-Bulk Correspondence in Disordered Non-Hermitian Systems
Zhi-Qiang Zhang, Hongfang Liu, Haiwen Liu +2
The consistency between eigenvalues calculated under open and periodic boundary conditions, named as {\it bulk-bulk correspondence} (), can be destroyed in systems w…
Real space topological invariant and higher-order topological Anderson insulator in two-dimensional non-Hermitian systems
Hongfang Liu, Ji-Kun Zhou, Bing-Lan Wu +2
We study the characterization and realization of higher-order topological Anderson insulator (HOTAI) in non-Hermitian systems, where the non-Hermitian mechanism ensures extra symme…
