Giant emitters in a structured bath with non-Hermitian skin effect
Lei Du, Lingzhen Guo, Yan Zhang, Anton Frisk Kockum
Abstract
By nonlocally coupling quantum emitters, making them ``giant,'' to a non-Hermitian structured bath where Bloch's theorem breaks down and the non-Hermitian skin effect appears, unconventional light-matter interactions can be designed and harnessed. It's shown that giant emitters in such a bath can undergo excitation amplification or attenuation and interact with each other in a nonreciprocal manner without decohering.
