| Abstract: | A three-dimensional G-P equation describing a Bose-Einstein condensation in spherical symmetry non-harmonic trap is presented. The ground-state solution of Bose-Einstein condensation with atomic interaction is investigated in numerical method. Further more, comparisons between harmonic and non-harmonic traps are also reported. |
| Keywords: | numerical solution of the Bose-Einstein condensation in three-dimensional non-harmonic trap |
