Topological Floquet engineering of a three-band optical lattice with dual-mode resonant driving
Dalmin Bae, Junyoung Park, Myeonghyeon Kim +3
We present a Floquet framework for controlling topological features of a one-dimensional optical lattice system with dual-mode resonant driving, in which both the amplitude and pha…
Variations of the Kibble-Zurek scaling exponents of trapped Bose gases
Tenzin Rabga, Yangheon Lee, Dalmin Bae +2
We study the vortex nucleation dynamics in inhomogeneous atomic Bose gases quenched into a superfluid phase and investigate the dependence of the Kibble-Zurek (KZ) scaling exponent…
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…
Synthetic Hall ladder with tunable magnetic flux
Jeong Ho Han, Dalmin Bae, Yong-il Shin
We describe a synthetic three-leg Hall ladder system with a tunable magnetic flux for neutral Yb atoms in a one-dimensional optical lattice. The ladder legs are formed by t…
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_…
