Engineering second-order topological insulators via coupling two first-order topological insulators
Lizhou Liu, Jiaqi An, Yafei Ren +3
We theoretically investigate the engineering of two-dimensional second-order topological insulators with corner states by coupling two first-order topological insulators. We find t…

Interlayer Coupling Induced Topological Phase Transition to Higher Order
Lizhou Liu, Jiaqi An, Yafei Ren +3
We theoretically find that the second-order topological insulator, i.e., corner states, can be engineered by coupling two copies of two-dimensional topological insul…

The General Principle behind Magnetization-induced Second-Order Topological Corner States in the Kane-Mele Model
Cheng-Ming Miao, Lizhou Liu, Yu-Hao Wan +2
We propose a general principle for realizing second-order topological corner states in the modified Kane-Mele model with magnetization. It is demonstrated that the sign of the edge…
