Magnetic-flux tunable electronic transport through domain walls in a three-dimensional second-order topological insulator
Zhe Hou, Ai-Min Guo
The three-dimensional (3D) topological insulators (TIs), hosting topologically protected helical surface states, can be promoted into second-order TIs when a diagonal Zeeman term,…

Exact mobility edges in quasiperiodic network models with slowly varying potentials
Hai-Tao Hu, Yang Chen, Xiaoshui Lin +3
Quasiperiodic models are important physical platforms to explore Anderson transitions in low dimensional systems, yet the exact mobility edges (MEs) are generally hard to be determ…

Hidden self-duality and exact mobility edges in quasiperiodic network models
Hai-Tao Hu, Xiaoshui Lin, Ai-Min Guo +3
In one-dimensional quasiperiodic systems, only a few models with exact mobility edges (MEs) have been constructed using generalized self-duality theory, Avila's global theory, or t…
