Three perspectives on entropy dynamics in a non-Hermitian two-state system
Alexander Felski, Alireza Beygi, Christos Karapoulitidis +1
A comparative study of entropy dynamics as an indicator of physical behavior in an open two-state system with balanced gain and loss is presented. We distinguish the perspective ta…
