โฆ Synopsis
A mixture of the multicomponent Bose-Einstein condensate
is considered, where each component moves with its own velocity.
As a result of the relative motion, the mixture stratifies when
the relative velocity reaches a critical value. Stability
conditions for a binary moving mixture are derived and the
critical velocity is found.

A survey is given of the present state of the art in studying Bose-Einstein condensation of dilute atomic gases. The bulk of attention is focused on the principal theoretical problems, though the related experiments are also mentioned. Both uniform and nonuniform trapped gases are considered. Existi
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
