An analytic solution of the Gross-Pitaevskii equation for a rotating Bose-Einstein condensate of trapped atoms describes the onset of vorticity when the rotational speed is increased, starting with the entry of the first vortex and followed by the formation of growing symmetric Wigner molecules. It explains the staircase of angular momentum jumps and the behavior of the bosonic occupancies observed in numerical studies. The similarity of this behavior and mesoscopic superconductors is discussed.
对于捕获原子的旋转玻色-爱因斯坦凝聚体，格罗斯-皮塔耶夫斯基方程的解析解描述了转速增加时涡度的产生，从第一个涡旋的进入开始，随后是不断增长的对称维格纳分子的形成。它解释了角动量跳跃的阶梯现象以及在数值研究中观察到的玻色子占据行为。文中还讨论了这种行为与介观超导体的相似性。
