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
The thermal conductivity of a trapped Bose condensed gas is calculated by using the Kubo formula approach. By evaluating the appropriate self-energies of the system the thermal relaxation time is calculated. Below the Bose-Einstein condensation temperature in addition to the relaxation time due to c
