1/2 Z Topological Invariants and the Half Quantized Hall Effect
Bo Fu, Shun-Qing Shen
The half-quantized Hall phase represents a unique metallic or semi-metallic state of matter characterized by a fractional quantum Hall conductance, precisely half of an integer …
Disordered Parity Anomalous Semimetal
Shi-Hao Bi, Bo Fu, Shun-Qing Shen
The parity anomalous semimetal is a topological state of matter characterized by its semi-metallic nature and a quantum Hall conductance of one-half ( is the elementar…
Dirac Fermions and Topological Phases in Magnetic Topological Insulator Films
Kai-Zhi Bai, Bo Fu, Shun-Qing Shen
We develop a Dirac fermion theory for topological phases in magnetic topological insulator films. The theory is based on exact solutions of the energies and the wave functions for…
Half Quantum Mirror Hall Effect
Bo Fu, Kai-Zhi Bai, Shun-Qing Shen
We report the discovery of the half-quantized mirror Hall effect, a novel quantum-anomaly induced by mirror symmetry in a strong topological insulator (TI) film. These films are kn…
