摘要：

For temperatures far below the critical temperature, the probability distribution of the phase of a Bose-Einstein condensate is investigated for the phase diffusion process due to collective excitations spontaneously created from the condensate. Our results show that the phase diffusion decreases with the increasing of the particle number in the condensate.
