Symmetry recovery of exceptional points and their dynamical encircling in a two-state system

Xu-Lin Zhang, Shubo Wang, Wen-Jie Chen +2

Exceptional points are degeneracies in non-Hermitian systems. A two-state system with parity-time (PT) symmetry usually has only one exceptional point beyond which the eigenmodes a…
