Edge and corner states in 2D non-Abelian topological insulators from an eigenvector frame rotation perspective
Tianshu Jiang, Ruo-Yang Zhang, Qinghua Guo +2
We propose the concept of 2D non-Abelian topological insulator which can explain the energy distributions of the edge states and corner states in systems with parity-time symmetry.…

Angular momentum-dependent topological transport and its experimental realization using a transmission line network
Tianshu Jiang, Meng Xiao, Wenjie Chen +4
Novel classical wave phenomenon analogs of the quantum spin Hall effect are mostly based on the construction of pseudo-spins. Here we show that the non-trivial topology of a system…

Dynamically encircling an exceptional point in anti-PT-symmetric systems: asymmetric mode switching for symmetry-broken states
Xu-Lin Zhang, Tianshu Jiang, Hong-Bo Sun +1
Dynamically encircling an exceptional point (EP) in parity-time (PT) symmetric systems shows an interesting chiral dynamics, leading to asymmetric mode switching in which the outpu…
