Topological phase transitions with and without energy gap closing
Yunyou Yang, Huichao Li, L. Sheng +3
Topological phase transitions in a three-dimensional (3D) topological insulator (TI) with an exchange field of strength are studied by calculating spin Chern numbers $C^\pm(k_z…

Coupling-Matrix Approach to the Chern Number Calculation in Disordered Systems
Y. F. Zhang, Y. Y. Yang, Yan Ju +4
The Chern number is often used to distinguish between different topological phases of matter in two-dimensional electron systems. A fast and efficient coupling-matrix method is des…

Time-reversal-symmetry-broken quantum spin Hall effect
Yunyou Yang, Zhong Xu, L. Sheng +3
Quantum spin Hall (QSH) state of matter is usually considered to be protected by time-reversal (TR) symmetry. We investigate the fate of the QSH effect in the presence of the Rashb…
