Multi-state Chiral Switching Through Adiabaticity Control in Encircling Exceptional Points
Aodong Li, Jian Wang, Andrea Alù +1
Dynamic encircling of exceptional points has attracted significant interest in recent years, as it can facilitate chiral transmission selectivity due to a nontrivial eigenstate evo…
