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…
Double exceptional points generated by the strong imaginary coupling of a non-Hermitian Hamiltonian in an optical microcavity
Kyu-Won Park, Jinuk Kim, Kabgyun Jeong
Exceptional points (EPs) have recently attracted considerable attention in the study of non-Hermitian systems and in applications such as sensors and mode switching. In particular,…
