Bose–Einstein Condensation of Ideal Bose Gases
Jun’ichi Ieda, Takeya Tsurumi, Miki Wadati
Abstract
Bose–Einstein condensation (BEC) is studied for ideal boson gases with a wide class of the dispersion relations. A criterion of the BEC, the transition temperature and a fraction of the condensate are calculated under the appropriate thermodynamic limits. The correspondence between the dispersion relation (spectrum) and the trap potential is shown. This gives the criterion for the trap shape and the dimensionality of the system.
