摘　　要：采用含时非线性薛定谔方程的数值解法模拟了两种情况下玻色爱因斯坦凝聚体的演化．一种是在初始状态中有两个包含粒子数差别很大、在空间上可区分的玻色爱因斯坦凝聚体的情况；Abstract We explore the time evolution of BEC condensates under different condition by solving the time dependent nonlinear Schrdinger equation(NLSE) that describes an inhomogeneous,weakly interacting Bose Einstein condensate at zero temperature.We present numerical results of interference of two condensates which have different number of atoms in them and examine the evolution of a Bose Einstein condensate which has split into two parts.
