One-dimensional behavior of elongated Bose-Einstein condensates
P. Bouyer, J. H. Thywissen, F. Gerbier +4
We study the properties of elongated Bose-Einstein condensates. First, we show that the dimensions of the condensate after expansion differs from the 3D Thomas-Fermi regime. We als…
The critical temperature of a trapped, weakly interacting Bose gas
Fabrice Gerbier, Joseph H. Thywissen, Simon Richard +3
We report on measurements of the critical temperature of a harmonically trapped, weakly interacting Bose gas as a function of atom number. Our results exclude ideal-gas behavior by…
Momentum distribution and correlation function of quasicondensates in elongated traps
F. Gerbier, J. H. Thywissen, S. Richard +3
We calculate the spatial correlation function and momentum distribution of a phase-fluctuating, elongated three-dimensional condensate, in a trap and in free expansion. We take the…
Phase coherence length of a Bose-Einstein condensate
F. Gerbier, S. Richard, J. H. Thywissen +3
We report on the measurement of the momentum distribution of an elongated Bose-Einstein condensate. A broadening of the distribution with increasing temperature is observed, which…
