Expansion of a degenerate Bose gas released from a pancakelike trap is numerically simulated under the assumption of separation of the motion in the plane of the loose initial trapping and the motion in the direction of the initial tight trapping. The initial conditions for the phase fluctuations are generated using the extension to the two-dimensional case of the description of the phase noise by the Ornstein-Uhlenbeck stochastic process. The numerical simulations, taking into account both the…

Probing the degree of coherence through the full 1D-3D dimensional crossover

We experimentally study a gas of quantum degenerate Rb atoms throughout the full dimensional crossover, from a one-dimensional (1D) system exhibiting phase fluctuations consistent with 1D theory to a

In this chapter we will present the one-dimensional (1d) quantum degenerate Bose gas (1d superfluid) as a testbed to experimentally illustrate some of the key aspects of quantum thermodynamics.

Dynamic phase fluctuations in potential-driven Bose–Einstein condensate

We report on the dynamics of a Bose–Einstein condensate in one and two dimensions driven by the time-dependent harmonic trapping potential. Without the inter-particle interaction, the condensate

In this chapter we review the basic concepts necessary for the realization of a degenerate 1D Bose gas, as well as the actual experimental implementation of these concepts.

Free expansion of quasi-2D Bose-Einstein condensates with quantized vortices

We observe that a density-depleted vortex core evolves into concentric density ripples in a freely-expanding quasi-two-dimensional Bose-Einstein condensate. The atomic density of the expanding



Probing phase fluctuations in a 2D degenerate Bose gas by free expansion.

The power spectrum of the density distribution of a freely expanding two-dimensional Bose gas is measured and the relative intensity of phase fluctuations is estimated from the normalized spectral peak strength and observed to decrease at lower temperatures, confirming the thermal nature of the phase fluctuations.

Two-point density correlations of quasicondensates in free expansion

We measure the two-point density correlation function of freely expanding quasicondensates in the weakly interacting quasi-one-dimensional (1D) regime. While initially suppressed in the trap, density

We investigate theoretically the evolution of the two-point density correlation function of a low-dimensional ultracold Bose gas after release from a tight transverse confinement. In the course of

A semiclassical description of the fluctuation properties of a one-dimensional many-body quantum system composed of interacting bosons based on the Ornstein-Uhlenbeck stochastic process is developed and compared with the Luttinger-liquid theory.

Ordering, metastability and phase transitions in two-dimensional systems

A new definition of order called topological order is proposed for two-dimensional systems in which no long-range order of the conventional type exists. The possibility of a phase transition
