Bose-Einstein Condensates in Time Dependent Traps
Yvan Castin, Ralph Dum
We present analytical results for the macroscopic wave function of a Bose-Einstein condensate in a time dependent harmonic potential. The evolution of the spatial density is a dila…
Coherence properties of a continuous atom laser
Yvan Castin, Ralph Dum, Emmanuel Mandonnet +2
We investigate the coherence properties of an atomic beam evaporatively cooled in a magnetic guide, assuming thermal equilibrium in the quantum degenerate regime. The gas experienc…
Nonlinear Matter Wave Dynamics with a Chaotic Potential
S. A. Gardiner, D. Jaksch, R. Dum +2
We consider the case of a cubic nonlinear Schrödinger equation with an additional chaotic potential, in the sense that such a potential produces chaotic dynamics in classical mecha…
Evaporative cooling of an atomic beam
E. Mandonnet, A. Minguzi, R. Dum +3
We present a theoretical analysis of the evaporative cooling of an atomic beam propagating in a magnetic guide. Cooling is provided by transverse evaporation. The atomic dynamics i…
Bose-Einstein condensates with vortices in rotating traps
Y. Castin, R. Dum
We investigate minimal energy solutions with vortices for an interacting Bose-Einstein condensate in a rotating trap. The atoms are strongly confined along the axis of rotation z,…
BCS Theory for Trapped Ultracold Fermions
G. Bruun, Y. Castin, R. Dum +1
We develop an extension of the well-known BCS-theory to systems with trapped fermions. The theory fully includes the quantized energy levels in the trap. The key ingredient is to m…
