Exceptional classifications of non-Hermitian systems

Exceptional classifications of non-Hermitian systems

Abstract Eigenstate coalescence in non-Hermitian systems is widely observed in diverse scientific domains encompassing optics and open quantum systems. Recent investigations have revealed that adiabatic encircling of exceptional points (EPs) leads to a nontrivial Berry phase in addition to an exchan...
