Probing early phase coarsening in a rapidly quenched Bose gas using off-resonant matter-wave interferometry
Tenzin Rabga, Yangheon Lee, Yong-il Shin
We experimentally investigate the evolution of spatial phase correlations in a rapidly quenched inhomogeneous Bose gas of rubidium using off-resonant matter-wave interferometry. We…
Vortex detection in atomic Bose-Einstein condensates using neural networks trained on synthetic images
Myeonghyeon Kim, Junhwan Kwon, Tenzin Rabga +1
Quantum vortices in atomic Bose-Einstein condensates (BECs) are topological defects characterized by quantized circulation of particles around them. In experimental studies, vortic…
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…
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_…
