Observation of von Kármán Vortex Street in an Atomic Superfluid Gas
Woo Jin Kwon, Joon Hyun Kim, Sang Won Seo +1
We report on the experimental observation of vortex cluster shedding from a moving obstacle in an oblate atomic Bose-Einstein condensate. At low obstacle velocities above a cri…
Role of thermal friction in relaxation of turbulent Bose-Einstein condensates
Joon Hyun Kim, Woo Jin Kwon, Yong-il Shin
In recent experiments, the relaxation dynamics of highly oblate, turbulent Bose-Einstein condensates (BECs) was investigated by measuring the vortex decay rates in various sample c…
Rotating a Bose-Einstein condensate by shaking an anharmonic axisymmetric magnetic potential
Seji Kang, J. Choi, S. W. Seo +2
We present an experimental method for rotating a Bose-Einstein condensate trapped in an axisymmetric magnetic potential. This method is based on the anharmonicity of the trapping p…
Relaxation of superfluid turbulence in highly oblate Bose-Einstein condensates
Woo Jin Kwon, Geol Moon, Jae-yoon Choi +2
We investigate thermal relaxation of superfluid turbulence in a highly oblate Bose-Einstein condensate. We generate turbulent flow in the condensate by sweeping the center region o…
Probing Phase Fluctuations in a 2D Degenerate Bose Gas by Free Expansion
Jae-yoon Choi, Sang Won Seo, Woo Jin Kwon +1
We measure the power spectrum of the density distribution of a freely expanding 2D degenerate Bose gas, where irregular density modulations gradually develop due to the initial pha…
