Dynamical transition in non-Hermitian Chern insulator
Zhi-Qiang Zhang, Yuan-Hang Ren, Ming Lu +1
We unveil a peculiar dynamical transition for the propagation of wave packets in non-Hermitian Chern insulators, where the evolution of the topological wave packets at the edge is…
Non-Hermitian Topology from Edge Transport in Hermitian Quantum Anomalous Hall Systems
Humian Zhou, Ming Lu, Chui-Zhen Chen +1
Non-Hermitian physics, known for exotic phenomena like exceptional points and the skin effect, has been most prominently realized in engineered systems relying on controlled gain a…
Theory of Correlated Hofstadter Spectrum in Magic-Angle Graphene
Chen Zhao, Zhaowen Miao, Zhen Ma +4
The magnetic-field-induced correlated Chern insulator (CCI) states in magic-angle twisted bilayer graphene (MATBG) have been intensively studied in experiments, but a simple and cl…
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…
Hofstadter spectrum in a semiconductor moiré lattice
Chen Zhao, Ming Wu, Zhen Ma +4
Recently, the Hofstadter spectrum of a twisted heterobilayer has been observed in experiment [C. R. Kometter, et al. Nat.Phys.19, 1861 (2023)], but the orig…
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…
Dissipation Enhanced Unidirectional Transport in Topological Systems
Ming Lu, Xue-Zhu Liu, Hailong Li +3
Dissipation is a common occurrence in real-world systems and is generally considered to be detrimental to transport. In this study, we examine the transport properties of a narrow…
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)…
Non-Hermiticity stabilized Majorana zero modes in semiconductor-superconductor nanowires
Hongchao Liu, Ming Lu, Yijia Wu +2
Coupled Majorana zero modes with nonzero energies are generally detrimental to the non-Abelian statistics due to the additional dynamic phase. Nevertheless, we show that a well-con…
Electrically Switchable van der Waals Magnon Valves
Guangyi Chen, Shaomian Qi, Jianqiao Liu +14
Van der Waals magnets have emerged as a fertile ground for the exploration of highly tunable spin physics and spin-related technology. Two-dimensional (2D) magnons in van der Waals…
Doubled Moiré Flat Bands in Double-twisted Few Layer Graphite
Zhen Ma, Shuai Li, Ming Lu +3
We study the electronic structure of a double-twisted few layer graphite (DTFLG), which consists of three few layer graphite (FLG), i.e. ABA-stacked graphene multilayer, stacked wi…
Valley-selective Floquet Chern Flat Bands in Twisted Multilayer Graphene
Ming Lu, Jiang Zeng, Haiwen Liu +2
We show that Floquet engineering with circularly polarized light (CPL) can selectively split the valley degeneracy of a twisted multilayer graphene (TMG), and thus generate a contr…
Transport study of the wormhole effect in three-dimensional topological insulators
Ming Gong, Ming Lu, Haiwen Liu +3
Inside a three-dimensional strong topological insulator, a tube with magnetic flux carries a pair of protected one-dimensional linear fermionic modes. This phenomenon is kno…

Jiang Zeng, Ming Lu, Haiwen Liu +2
Though several theoretical models have been proposed to design electronic flat-bands, the definite experimental realization in two-dimensional atomic crystal is still lacking. Here…
