M. Khanbekyan, Jan Wiersig
Abstract
The authors show that the peculiar spectral response of the electromagnetic field of a high-Q cavity operating at an exceptional point modifies the spontaneous emission of a single emitter in the strong coupling regime. The theory, based on macroscopic QED in dispersing and absorbing media, demonstrates much longer effective decay times in the exceptional point case in comparison to the single-mode case
