囚禁原子气体中持续电流的亚稳性
Metastability of persistent currents in trapped gases of atoms
摘要：
我们研究的条件下，引起亚稳态，持续电流中的一个被困的玻色-爱因斯坦凝聚体。持续电流稳定性的一个必要条件是俘获势不是离陷阱中心距离的单调递增函数。持续的电流还要求原子间的相互作用足够强和排斥。最后，任何偏离中心的旋涡状态被证明是不稳定的，而驱动气体显示滞后。
英文摘要：
We examine the conditions that give rise to metastable, persistent currents in a trapped Bose-Einstein condensate. A necessary condition for the stability of persistent currents is that the trapping potential is not a monotonically increasing function of the distance from the trap center. Persistent currents also require that the interatomic interactions are sufficiently strong and repulsive. Finally, any off-center vortex state is shown to be unstable, while a driven gas shows hysteresis.
