✦ Synopsis

The theory of resonant generation of nonground-state
Bose-Einstein condensates is extended to Bose-condensed systems at
finite temperature. The generalization is based on the notion of
representative statistical ensembles for Bose systems with broken
global gauge symmetry. Self-consistent equations are derived
describing an arbitrary nonequilibrium nonuniform Bose system. The
notion of finite-temperature topological coherent modes,
coexisting with a cloud of noncondensed atoms, is introduced. It
is shown that resonant generation of these modes is feasible for a
gas of trapped Bose atoms at finite temperature.

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 t
