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…
Pushing single atoms near an optical cavity
Dowon Lee, Taegyu Ha, Donggeon Kim +3
Optical scattering force is used to reduce the loading time of single atoms to a cavity mode. Releasing a cold atomic ensemble above the resonator, we apply a push beam along the d…
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…
Precise and extensive characterization of an optical resonator for cavity-based quantum networks
Dowon Lee, Myunghun Kim, Jungsoo Hong +6
Cavity-based quantum node is a competitive platform for distributed quantum networks. Here, we characterize a high-finesse Fabry-Perot optical resonator for coupling single or few…
