摘要
从理论上应用辛算法数值求解一维含时GP方程,研究存在陷浮势和陷浮势为零时三个玻色-爱因斯坦凝聚体间的干涉.当陷浮势存在时,玻色-爱因斯坦凝聚体间发生弹性碰撞;如果在t=0时陷浮势为零,三个凝聚体间发生干涉现象,并且发现几率密度随着时间的演化是振荡的.
Symplectic method is applied to solve 1D time-dependent Gross-Pitaevskii（GP） equation numerically.Interference of three Bose-Einstein condensates（BECs） is investigated with or without a trapping potential.Elastic collisions of BECs occur as trapping potential exists.If trapping potential is zero at t=0,interference of three BECs is observed and oscillation of probability density is found.
