Nonequilibrium Bose systems and nonground-state Bose-Einstein condensates | V.I. Yukalov
; | Date: |
26 Jun 2006 | Journal: | Laser Phys. Lett. 3 (2006) 406-414 | Subject: | Statistical Mechanics; Mesoscopic Systems and Quantum Hall Effect | Abstract: | 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. | Source: | arXiv, cond-mat/0606654 | Services: | Forum | Review | PDF | Favorites |
