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…
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…
Ion trap with gold-plated alumina: substrate and surface characterization
Myunghun Kim, Keumhyun Kim, Jungsoo Hong +7
We describe a complete development process of a segmented-blade linear ion trap. Alumina substrate is characterized with an X-ray diffraction and loss-tangent measurement. The blad…
Numerical investigation of a segmented-blade ion trap with biasing rods
Jungsoo Hong, Myunghun Kim, Hyegoo Lee +1
We report a numerical study of a linear ion trap that has segmented blades and biasing rods. Our system consists of radio frequency (rf) blades, dc blades with ten separate electro…
Locking Multi-laser Frequencies to a Precision Wavelength Meter: Application to Cold Atoms
Junwoo Kim, Keumhyun Kim, Dowon Lee +6
We herein report a simultaneous frequency stabilization of two 780-nm external cavity diode lasers using a precision wavelength meter (WLM). The laser lock performance is character…
