Dynamically encircling exceptional points: in situ control of encircling loops and the role of the starting point
Xu-Lin Zhang, Shubo Wang, Bo Hou +1
The most intriguing properties of non-Hermitian systems are found near the exceptional points (EPs) at which the Hamiltonian matrix becomes defective. Due to the complex topologica…

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…
