玻色-爱因斯坦凝聚体中的Von Kármán涡街
Von Kármán vortex street in a Bose-Einstein condensate
摘要：
研究了在玻色-爱因斯坦凝聚体中运动的障碍势的涡旋脱落。长寿命的交替排列的涡对被发现在尾流中形成，如在经典粘性流体中的冯卡门涡街。系统地研究了各种形式的旋涡脱落，并计算了障碍物上的阻力。结果表明，这种现象可以在一个陷阱系统中观察到。
英文摘要：
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, as for the von Kármán vortex street in classical viscous fluids. Various patterns of vortex shedding are systematically studied and the drag force on the obstacle is calculated. It is shown that the phenomenon can be observed in a trapped system.
