AI 中文摘要
我们给出了处于时间依赖谐振势中的玻色 - 爱因斯坦凝聚体宏观波函数的分析结果。空间密度的演化是一种膨胀，由三个缩放因子表征，这使得动力学有经典解释。该方法是分析凝聚体膨胀和集体激发近期实验结果的有效工具。
英文摘要
We present analytical results for the macroscopic wave function of a Bose-Einstein condensate in a time dependent harmonic potential. The evolution of the spatial density is a dilatation, characterized by three scaling factors which allow a classical interpretation of the dynamics. This approach is an efficient tool for the analysis of recent experimental results on the expansion and collective excitation of a condensate.
