PT-symmetric topological near-zero interface state
Zhenjuan Liu, Kaiwen Ji, Haohao Wang +6
Photonic systems with parity-time (PT) symmetry and topology are attracting considerable attentions. In this work, topological near-zero edge states are studied in PT-symmetric pho…

Synthetic topological insulator with periodically modulated effective gauge fields
Zengrun Wen, Baole Lu, Kaiwen Ji +4
We study both theoretically and numerically the topological edge states in synthetic photonic lattice with finitely periodic gauge potentials. The effective gauge fields are implem…
