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.
A two-dimensional Gross-Pitaevskii equation describing Bose-Einstein condensation in an axial symmetry nonharmonic 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.
