玻色-爱因斯坦凝聚态原子气体中的孤波和Yrast态
Solitary waves and yrast states in Bose-Einstein condensed gases of atoms
摘要：
考虑玻色-爱因斯坦凝聚气体在一维周期性边界条件下，我们证明了，非常普遍的，孤立波和旋转激发一致。这种精确的等价性使我们能够在这两个问题中存在的许多效应之间建立联系，其中许多效应已经使用平均场近似进行了研究。
英文摘要：
Considering a Bose-Einstein condensed gas confined in one dimension with periodic boundary conditions, we demonstrate that, very generally, solitary-wave and rotational excitations coincide. This exact equivalence allows us to establish connections between a number of effects that are present in these two problems, many of which have been studied using the mean-field approximation.
