中文摘要：

采用辛算法数值求解一维含时Gross-Pitaevskii方程.数值模拟玻色爱因斯坦凝聚体的＂Breathing＂特征,研究撤掉简谐势阱时两个凝聚体相互作用产生的干涉现象及两个凝聚体相位差发生变化时凝聚体的动力学性质.

英文摘要：

Symplectic method is applied to solve numerically 1D time-dependent Gross-Pitaevskii equation. ＂Breathing＂ of the condensate is numerically illustrated. Interaction of two Bose-Einstein condensates is investigated as external potential is zero at t=0. Interference between two condensates is observed. Evolution of density due to interference at various relative phases is studied.
