Observation of anti-PT-symmetry and higher-order exceptional point PT-symmetry in ternary systems for single-mode operation

Observation of anti-PT-symmetry and higher-order exceptional point PT-symmetry in ternary systems for single-mode operation

Abstract Nowadays, topological parity-time (PT) and anti- parity-time (APT) symmetry systems have attracted substantial attention due to their noticeable features and specific applications. The emergence of exceptional points in these systems plays a direct role in their overall responses and causes...
