In-situ tuning of cavity dissipation and a topological transition in an atom-nanotip-cavity system
Taegyu Ha, Kiyanoush Goudarzi, Dowon Lee +6
We theoretically investigate a method for tuning a dissipation rate in an atom-cavity system. By inserting a nanotip into the cavity mode, we estimate that the cavity dissipation r…
Numerical analysis of a superradiance-sideband-assisted laser with a zero frequency pulling and a narrow linewidth
Mingyu Jeon, Jinuk Kim, Kyungwon An
Numerical simulations based on the quantum Langevin equations have been performed for a large number of two-level atoms in a beam interacting with a low-Q cavity with the atomic in…
A photonic quantum engine driven by superradiance
Jinuk Kim, Seung-hoon Oh, Daeho Yang +3
Performance of nano- and micro-scale heat engines can be improved with a help from quantum mechanical phenomena. Recently, heat reservoirs with quantum coherence have been proposed…
Third-order exceptional point in an ion-cavity system
Jinuk Kim, Taegyu Ha, Donggeon Kim +5
We investigate a scheme for observing the third-order exceptional point (EP3) in an ion-cavity setting. In the lambda-type level configuration, the ion is driven by a pump field, a…
Behavior of Shannon entropy around an exceptional point in an open microcavity
Kyu-Won Park, Jinuk Kim, Songky Moon +1
We have investigated the Shannon entropy around an exceptional point (EP) in an open elliptical microcavity as a non-Hermitian system. The Shannon entropy had an extreme value at t…
Shannon entropy as an indicator of spatial resolution for morphology of mode pattern in dielectric microcavity
Kyu-Won Park, SongKy Moon, JinUk Kim
We present the Shannon entropy as an indicator of spatial resolution for morphology of resonance mode pattern in dielectric micro cavity. We obtain two types of optimized mesh poin…
