Bénard–von Kármán Vortex Street in a Bose-Einstein Condensate
Bénard–von Kármán Vortex Street in a Bose-Einstein Condensate
Vortex shedding from an obstacle potential moving in a Bose-Einstein condensate is investigated. Long-lived alternately aligned vortex pairs are found to form in the wake, which is similar to the Bénard-von Kármán vortex street in classical viscous fluids. Various patterns of vortex shedding are systematically studied and the drag force …
