High performance imaging of Yb atom in shallow clock-magic tweezer by alternating dual-tone narrowline cooling
Yunheung Song, Kangheun Kim, Jeong Ho Han +2
We demonstrate imaging Yb single atoms in clock-magic tweezers of 759.4 nm wavelength, with above 99.9% fidelity and survival. We use alternating dual-tone narrowline imagi…
Precise measurements of optical Feshbach resonances of Yb atoms
Min-Seok Kim, Jeongwon Lee, Jae Hoon Lee +2
We present precise measurements of the optical Feshbach resonances (OFRs) of Yb atoms for the intercombination transition. We measure the photoassociation (PA) spectra of a…
Core-Shell Magneto-Optical Trap for Alkaline-Earth-Metal-Like Atoms
Jeongwon Lee, Jae Hoon Lee, Jiho Noh +1
We propose and demonstrate a new magneto-optical trap (MOT) for alkaline-earth-metal-like (AEML) atoms where the narrow transition and the broad $…
Observation of the universal jump across the Berezinskii-Kosterlitz-Thouless transition in two-dimensional Bose gases
Jiho Noh, Jeongwon Lee, Jongchul Mun
The physics in two-dimensional (2D) systems is very different from what we observe in three-dimensional (3D) systems. Thermal fluctuations in 2D systems are enhanced, and they prev…
Absolute frequency measurement of 1S0 (F = 1/2) - 3P0 (F = 1/2) transition of 171Yb atoms in a one-dimensional optical lattice at KRISS
Chang Yong Park, Dai-Hyuk Yu, Won-Kyu Lee +9
We measured the absolute frequency of the optical clock transition 1S0 (F = 1/2) - 3P0 (F = 1/2) of 171Yb atoms confined in a one-dimensional optical lattice and it was determined…
Phase diagram for a Bose-Einstein condensate moving in an optical lattice
Jongchul Mun, Patrick Medley, Gretchen K. Campbell +3
The stability of superfluid currents in a system of ultracold bosons was studied using a moving optical lattice. Superfluid currents in a very weak lattice become unstable when the…
