| 摘 要： | 探讨了准二维条件下玻色-爱因斯坦凝聚体的模型,给出了准二维条件下体系所满足的G-P方程,利用Crank-Nicolson算法对含时间的G-P方程进行了数值求解。结果表明,不论原子的散射长度是正还是负,玻色-爱因斯坦凝聚体都能够形成。

| Abstract: | The model of Bose-Einstein condensate in quasi-2D condition was discussed, the quasi-2D G-P equation was given. By using Crank-nicolson scheme, the time-dependent G-P equation is solved numerically. Bose-Einstein Condensate can form in both positive and negative scattering length conditions. |
