摘要
利用数值方法和托马斯费米近似求解非线性薛定谔方程(Gross-Pitaevskii方程),应用量子变分原理分析化学势随一维散射强度的变化,研究玻色-爱因斯坦凝聚体基态稳定性,并计算了7Li原子最大凝聚原子数.
In this paper, the numerical method and Thomas-Fermi approximation are used to solve the nonlinear Schrodinger equation （Gross-Pitaevskii equation）. The quantum variational principle is applied to analyze the variation of chemical potential with one-dimensional scattering intensity. The ground state stability of Bose-Einstein condensates is studied, and the maximum number of condensed atoms of is calculated.
