Giant emitters in a structured bath with non-Hermitian skin effect

L Du, L Guo, Y Zhang, AF Kockum - Physical Review Research, 2023 - APS
Giant emitters derive their name from nonlocal field-emitter interactions and feature diverse
self-interference effects. Authors of most of the existing works on giant emitters have …

Anomalous behaviors of quantum emitters in non-hermitian baths

Z Gong, M Bello, D Malz, FK Kunst - Physical Review Letters, 2022 - APS
Both non-Hermitian systems and the behavior of emitters coupled to structured baths have
been studied intensely in recent years. Here, we study the interplay of these paradigmatic …

[HTML][HTML] Non-Hermitian extended midgap states and bound states in the continuum

M Zelenayova, EJ Bergholtz - Applied Physics Letters, 2024 - pubs.aip.org
We investigate anomalous localization phenomena in non-Hermitian systems by solving a
class of generalized Su–Schrieffer–Heeger/Rice–Mele models and by relating their …
