Metallic Quantized Anomalous Hall Effect without Chiral Edge States
Kai-Zhi Bai, Bo Fu, Zhenyu Zhang +1
The quantum anomalous Hall effect (QAHE) is a topological state of matter with a quantized Hall resistance. It has been observed in some two-dimensional insulating materials such a…
Signature of Parity Anomaly: Crossover from One Half to Integer Quantized Hall Conductance in a Finite Magnetic Field
Huan-Wen Wang, Bo Fu, Shun-Qing Shen
The pursuit of understanding parity anomaly in condensed matter systems has led to significant advancements in both theoretical and experimental research in recent years. In this s…
Theory of anomalous Hall effect in transition-metal pentatelluride and
Huan-Wen Wang, Bo Fu, Shun-Qing Shen

A Solvable Model for Discrete Time Crystal Enforced by Nonsymmorphic Dynamical Symmetry
Zi-Ang Hu, Bo Fu, Xiao Li +1
Discrete time crystal is a class of nonequilibrium quantum systems exhibiting subharmonic responses to external periodic driving. Here we propose a class of discrete time crystals…
On the half-quantized Hall conductance of massive surface electrons in magnetic topological insulator films
Rui Chen, Shun-Qing Shen
In topological insulators, massive surface bands resulting from local symmetry breaking are believed to exhibit a half-quantized Hall conductance. However, such scenarios are obvio…
