Topological Hierarchy Insulators and Topological Fractal Insulators
Jing He, Chun-Li Zang, Ying Liang +1
Topological insulators are new states of quantum matter with metallic edge/surface states. In this paper, we pointed out that there exists a new type of particle-hole symmetry-prot…

Effects of Attractive correlation on Topological Flat-bands Model
Chun-Li Zang, Jing He, Ya-Jie Wu
In this paper, we study the effects of attractive correlation on the topological insulator () with topological flat-bands using an extended attractive Kane-Mele-Hubbard model (…
