Route towards Localization for Quantum Anomalous Hall Systems with Chern Number 2
Zhi-Gang Song, Yan-Yang Zhang, Jun-Tao Song +1
The quantum anomalous Hall system with Chern number 2 can be destroyed by sufficiently strong disorder. During its process towards localization, it was found that the electronic st…
Quantization of Topological Invariants under Symmetry-Breaking Disorder
Juntao Song, Emil Prodan
In the strictly periodic setting, the electric polarization of inversion-symmetric solids with and without time-reversal symmetry and the isotropic magneto-electric response functi…
Disorder and metal-insulator transitions in Weyl semimetals
Chui-Zhen Chen, Juntao Song, Hua Jiang +3
The Weyl semimetal (WSM) is a newly proposed quantum state of matter. It has Weyl nodes in bulk excitations and Fermi arcs surface states. We study the effects of disorder and loca…
Building topological device through emerging robust helical surface states
Zibo Wang, Juntao Song, Haiwen Liu +2
We propose a nonlocal manipulation method to build topological devices through emerging robust helical surface states in Z_2=0 topological systems. Specifically, in a ribbon of Z_2…
