Modified semiclassical approximation for trapped Bose gases
V. I. Yukalov
A generalization of the semiclassical approximation is suggested allowing for an essential extension of its region of applicability. In particular, it becomes possible to describe…
Topological Coherent Modes in Trapped Bose Gas
V. I. Yukalov, K. -P. Marzlin, E. P. Yukalova +1
The report reviews the problem of topological coherent modes, which are nonlinear collective states of Bose-condensed atoms. Such modes can be generated by means of alternating ext…
Nonlinear spin relaxation in strongly nonequilibrium magnets
V. I. Yukalov
A general theory is developed for describing the nonlinear relaxation of spin systems from a strongly nonequilibrium initial state, when, in addition, the sample is coupled to a re…
Dynamics of Bose-Einstein Condensates in One-Dimensional Optical Lattices in the Presence of Transverse Resonances
K. -P. Marzlin, V. I. Yukalov
The dynamics of Bose-Einstein condensates in the lowest energy band of a one-dimensional optical lattice is generally disturbed by the presence of transversally excited resonant st…
Dynamics of Nonground-State Bose-Einstein Condensates
V. I. Yukalov, E. P. Yukalova
Dilute Bose gases, cooled down to low temperatures below the Bose-Einstein condensation temperature, form coherent ensembles described by the Gross-Pitaevskii equation. Stationary…
Coherence phenomena
V. I. Yukalov
The basic notions related to coherence phenomena are formulated. Two types of coherence are described, state coherence and transition coherence. Useful characteristics for quantify…
