Efficient Quantum Frequency Conversion of Ultra-Violet Single Photons from a Trapped Ytterbium Ion
Seungwoo Yu, Kyungmin Lee, Sumin Park +4
Ion trap system is a leading candidate for quantum network privileged by its long coherence time, high-fidelity gate operations, and the ion-photon entanglement that generates an i…
Suppression of Spontaneous Defect Formation in Inhomogeneous Bose Gases
Myeonghyeon Kim, Tenzin Rabga, Yangheon Lee +3
In phase transition dynamics involving symmetry breaking, topological defects can be spontaneously created but it is suppressed in a spatially inhomogeneous system due to the sprea…
Vortex shedding frequency of a moving obstacle in a Bose-Einstein condensate
Younghoon Lim, Yangheon Lee, Junhong Goo +2
We experimentally investigate the periodic vortex shedding dynamics in a highly oblate Bose-Einstein condensate using a moving penetrable Gaussian obstacle. The shedding frequency…
Universal Early Coarsening of Quenched Bose Gases
Junhong Goo, Yangheon Lee, Younghoon Lim +3
We investigate the early coarsening dynamics of an atomic Bose gas quenched into a superfluid phase. Using a two-step quench protocol, we effectively control the cooling rates, $r_…
Defect Saturation in a Rapidly Quenched Bose Gas
Junhong Goo, Younghoon Lim, Yong-il Shin
We investigate the saturation of defect density in an atomic Bose gas rapidly cooled into a superfluid phase. The number of quantum vortices, which are spontaneously created in the…
Large-area Rb Bose-Einstein condensate in a clipped-Gaussian optical dipole trap
Younghoon Lim, Junhong Goo, Haneul Kwak +1
We demonstrate a production of large-area Rb Bose-Einstein condensates (BECs) using a non-Gaussian optical dipole trap (ODT). The ODT is formed by focusing a symmetrically t…
