| Abstract: | This paper calculated the semi-axes length and particles density of Bose-Einstein Condensation with quasi one-dimensional,quasi-two-dimensional,spherically and axial symmetric.With the approach minimizing ground-state energy and equating potential energy and interactional energy,issues discussed in the paper include the analytical expressions of the condensation semi-axes length,comparative analysis of theoretical values and experimental data of particles density,and collapse critical particle number of attractive interaction system. |
| Keywords: | Bose-Einstein Condensation Collapse critical particle number Semi-axes length Particles density |
