Fluctuations of the number of particles for the dilute interacting gas with Bose-Einstein condensate are considered. It is shown that in the Bogolubov theory these fluctuations are normal. The fluctuations of condensed as well as noncondensed particles are also normal both in canonical and grand can
We study the fluctuation of the number of particles in ideal Bose Einstein condensates, both within the canonical and the microcanonical ensemble. Employing the Mellin Barnes transformation, we derive simple expressions that link the canonical number of condensate particles, its fluctuation, and the
