摘要:

本文报道了在$^{87}Rb$玻色-爱因斯坦凝聚体中通过振荡激发凝聚体产生三涡旋团簇的实验结果。这个过程可以创建两种循环的漩涡,因此我们能够使用相同的机制创建几种类型的漩涡群。三涡结构主要有两种类型,即等边三角形排列和直线排列。我们将这些最稳定的结构分别解释为三个具有相同环流的涡旋和一个涡旋-反涡旋-涡旋群。线性构型很可能是预测的静止涡团的第一个实验特征。

英文摘要:

We report on the creation of three-vortex clusters in a $^{87}Rb$ Bose-Einstein condensate by oscillatory excitation of the condensate. This procedure can create vortices of both circulation, so that we are able to create several types of vortex clusters using the same mechanism. The three-vortex configurations are dominated by two types, namely, an equilateral-triangle arrangement and a linear arrangement. We interpret these most stable configurations respectively as three vortices with the same circulation, and as a vortex-antivortex-vortex cluster. The linear configurations are very likely the first experimental signatures of predicted stationary vortex clusters.
