We report on the measurement of the spectral functions of noninteracting ultracold atoms in
a three-dimensional disordered potential resulting from an optical speckle field. Varying the …

We analyze the extraction from a trapped Bose-Einstein condensate to a nontrapping state
of a coherent atomic beam and its subsequent fall, at T= 0 K. Our treatment fully takes gravity …

We present a fully quantum-mechanical treatment of a single-mode atomic cavity with a
pumping mechanism and an output coupling to a continuum of external modes. This system …

We present a quantun-mechanical treatment of the coherence properties of a single-mode
atom laser. Specifically, we focus on the quantum phase noise of the atomic field as …

The transverse mode of an atom laser beam that is outcoupled from a Bose–Einstein
condensate is investigated and is found to be strongly determined by the mean-field …

We present a theoretical model for the propagation of non-self-interacting atom laser beams.
We start from a general propagation integral equation and we use the same approximations …

Atom lasers based on rf outcoupling from a trapped Bose-Einstein condensate can be
described by a set of generalized, coupled Gross-Pitaevskii equations (GPEs). If not only …

By direct comparison between experiment and theory with no adjustable parameters, we
show how the classical fluctuations on a multistate atom laser beam increase with …

The dynamics of atom lasers with a continuous output coupler based on two-photon Raman
transitions is investigated. With the help of the time-convolutionless projection operator …

Based on a microscopic model of an open system consisting of a boson field coupled
linearly to a system, we formulate quantum trajectories as continuous measurements of the …
