Phys. Rev. A 68, 035604 (2003) [4 pages]Two characteristic temperatures for a Bose-Einstein condensate of a finite number of particlesReceived 25 April 2003; published 29 September 2003 We consider two characteristic temperatures for a Bose-Einstein condensate, which are related to certain properties of the condensate statistics. We calculate them for an ideal gas confined in power-law traps and show that they approach the critical temperature in the limit of large number of particles. The considered characteristic temperatures can be useful in the studies of Bose-Einstein condensates of a finite number of atoms indicating the point of a phase transition. © 2003 The American Physical Society URL:
