Observation of deviations from ideal gas thermodynamics in a trapped Bose-Einstein condensed gas
Fabrice Gerbier, Joseph H. Thywissen, Simon Richard +3
We have investigated experimentally the finite-temperature properties of a Bose-Einstein condensed cloud of Rb atoms in a harmonic trap. Focusing primarily on condensed frac…
Momentum Spectroscopy of Phase Fluctuations of an Elongated Bose-Einstein Condensate
A. Aspect, S. Richard, F. Gerbier +4
We have measured the momentum distribution of an elongated BEC (aspect ratio of 152), for temperatures below the critical temperature. The corresponding coherence length is signifi…
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 spectroscopy of 1D phase fluctuations in Bose-Einstein condensates
S. Richard, F. Gerbier, J. H. Thywissen +3
We measure the axial momentum distribution of Bose-Einstein condensates with an aspect ratio of 152 using Bragg spectroscopy. We observe the Lorentzian momentum distribution charac…
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…
