Synchronized in-gap edge states and robust copropagation in topological insulators without magnetic flux
Liangcai Xie, Tianyi He, Liang Jin
Copropagation of antichiral edge states in the metallic phase requires the bulk states as counterpropagating modes. Without the band gap protection, the copropagation along the bou…

Probing Bulk Band Topology from Time Boundary Effect in Synthetic Dimension
Huisheng Xu, Zhaohui Dong, Luqi Yuan +1
An incident wave at a temporal interface, created by an abrupt change in system parameters, generates time-refracted and time-reflected waves. We find topological characteristics a…
