Dynamic similarity of vortex shedding in a superfluid flowing past a penetrable obstacle
Junhwan Kwon, Y. Shin
We numerically investigate wake dynamics in a superfluid flowing past a penetrable obstacle. Unlike an impenetrable object, a penetrable obstacle does not fully deplete the density…
Random spin textures in turbulent spinor Bose-Einstein condensates
Jong Heum Jung, Junghoon Lee, Jongmin Kim +1
We numerically investigate the stationary turbulent states of spin-1 Bose-Einstein condensates under continuous spin driving. We analyze the entanglement entropy and magnetization…
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…
Half-quantum vortex generation in a two-component Bose-Einstein condensate by an oscillatory magnetic obstacle
Jong Heum Jung, Yong-il Shin
We numerically investigate the dynamics of vortex generation in a two-dimensional, twocomponent Bose-Einstein condensate subjected to an oscillatory magnetic obstacle. The obstacle…
Spin-driven stationary turbulence in spinor Bose-Einstein condensates
Deokhwa Hong, Junghoon Lee, Jongmin Kim +4
We report the observation of stationary turbulence in antiferromagnetic spin-1 Bose-Einstein condensates driven by a radio-frequency magnetic field. The magnetic driving injects en…
