In this paper, the evolution of Bose-Einstein condensates falling under gravity and bouncing off a mirror formed by a far-detuned sheet of light is investigated.Abstract:
We investigate the evolution of Bose-Einstein condensates falling under gravity and bouncing off a mirror formed by a far-detuned sheet of light. After reflection, the atomic density profile develops splitting and interference structures which depend on the drop height, on the strength of the light sheet, as well as on the initial mean field energy and size of the condensate. We compare experimental results with simulations of the Gross-Pitaevski equation. A comparison with the behavior of bouncing thermal clouds allows us to identify quantum features specific for condensates. © 1999 The American Physical Society.read more

TL;DR: In this paper, a review of the recent theoretical and experimental advances in the study of ultra-cold gases made of bosonic particles interacting via the long-range, anisotropic dipole-dipole interaction, in addition to the short-range and isotropic contact interaction usually at work in ultracold gases is presented.

Experimental demonstration of painting arbitrary and dynamic potentials for Bose–Einstein condensates
TL;DR: In this paper, a rapidly moving laser beam is used to "paint" a time-averaged optical dipole potential in order to create BECs in a variety of geometries, including toroids, ring lattices and square lattices.

Vortices in a trapped dilute Bose-Einstein condensate
TL;DR: In this paper, the authors review the theory of vortices in trapped dilute Bose-Einstein condensates and compare theoretical predictions with existing experiments and consider the effect of thermal quasiparticles on vortex normal modes as well as possible mechanisms for vortex dissipation.
