Fully quantum mechanical moment of inertia of a mesoscopic ideal Bose gas
Jens Schneider, Hartmut Wallis
The superfluid fraction of an atomic cloud can be defined using the cloud's response to a rotation of the external potential, i.e. the moment of inertia. In this paper we derive an…
Theory of atomic diffraction from evanescent waves
Carsten Henkel, Hartmut Wallis, Nathalie Westbrook +4
We review recent theoretical models and experiments dealing with the diffraction of neutral atoms from a reflection grating, formed by a standing evanescent wave. We analyze diffra…
Mesoscopic Fermi gas in a harmonic trap
J. Schneider, H. Wallis
We study the thermodynamical properties of a mesoscopic Fermi gas in view of recent possibilities to trap ultracold atoms in a harmonic potential. We focus on the effects of shell…
Output of a pulsed atom laser
H. Steck, M. Naraschewski, H. Wallis
We study the output properties of a pulsed atom laser consisting of an interacting Bose-Einstein condensate (BEC) in a magnetic trap and an additional rf field transferring atoms t…
Interference of Bose condensates
M. Naraschewski, H. Wallis, A. Schenzle +2
We investigate the prospects of atomic interference using samples of Bose condensed atoms. First we show the ability of two independent Bose condensates to create an interference p…
