【摘要】 通过能量泛函的方法得到描述囚禁在非谐势阱中玻色-爱因斯坦凝聚体的二维G-P方程数值解,讨论原子间相互作用和非谐振势能项对玻色-爱因斯坦凝聚体的分布、能量和化学势的影响.
【Abstract】 A two-dimensional Gross-Pitaevskii equation describing Bose-Einstein condensation in an axial symmetry non-harmonic trap is solved.Converged wave functions,chemical potentials,and internal energies in Bose-Einstein condensation are obtained.Ground-state of Bose-Einstein condensation with atomic interaction is investigated.A comparison between harmonic and non-harmonic traps is reported.
