Observation of vortex-antivortex pairing in decaying 2D turbulence of a superfluid gas
Sang Won Seo, Bumsuk Ko, Joon Hyun Kim +1
In a two-dimensional (2D) classical fluid, a large-scale flow structure emerges out of turbulence, which is known as the inverse energy cascade where energy flows from small to lar…
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…
