We discuss the dynamic properties of a trapped Bose-condensed gas under variations of the confining field and find analytical scaling solutions for the evolving coherent state ~condensate!. We further discuss the characteristic features and the depletion of this coherent state. @S1050-2947~96!50209-X# PACS number~s!: 03.75.Fi, 34.20.Cf The recent successful experiments on Bose-Einstein condensation ~BEC! in trapped ultracold alkali atom gases @1‐3# open a unique possibility to investigate… 
Quantum dynamics of the phase of a Bose–Einstein condensate
Abstract In this review we discuss the dynamics of the phase of trapped Bose–Einstein condensates. In particular we consider the phenomena of phase decoherence (termed also as phase collapse, or
Time-of-flight expansion of binary Bose-Einstein condensates at finite temperature.
Ultracold quantum gases provide a unique setting for studying and understanding the properties of interacting quantum systems. Here, we investigate a multi-component system of $^{87}$Rb--$^{39}$K
The recent realization of Bose-Einstein condensation in atomic gases opens new possibilities for observation of macroscopic quantum phenomena. There are two important features of the system - weak
Disorder-induced trapping versus Anderson localization in Bose–Einstein condensates expanding in disordered potentials
We theoretically investigate the localization of an expanding Bose–Einstein condensate (BEC) with repulsive atom–atom interactions in a disordered potential. We focus on the regime where the initial
Quantum Spin Dynamics of Individual Neutral Impurities Coupled to a Bose-Einstein Condensate.
It is shown that, despite high bath densities and, thus, fast thermalization rates, the impurity coherence is not affected by the bath, realized a regime of sympathetic cooling while maintaining internal state coherence, paving the way toward the nondestructive probing of quantum many-body systems via localized impurities.
Nonlinear dynamics of a Bose condensed gas
Abstract We investigate the dynamic behavior of a Bose-condensed gas of alkali atoms interacting with repulsive forces and confined in a magnetic trap at zero temperature. Using the Thomas-Fermi
Dynamics of quantum vortices at finite temperature
In this thesis, we perform investigations into the behaviour of finite-temperature degenerate Bose gases using a classical-field formalism, focussing in particular on the dynamics of quantum vortices
Dynamical excitation of the Bogoliubov vacuum in a two-component Bose-Einstein condensates
We investigate the parametric amplification of the zero-point fluctuations in the spin modes of a two-component Bose-Einstein condensate, that is triggered by the dynamical evolution of the
Time-varying Bose–Einstein condensates
Bose–Einstein condensates (BECs), a state of matter formed when a low-density gas of bosons is cooled to near absolute zero, continue to motivate novel work in theoretical and experimental physics.
One-dimensional Bose gas on an atom chip
We describe experiments investigating the (coherence) properties of a finite-temperature one-dimensional (1D) Bose gas with repulsive interactions. The confining magnetic field is generated with a
