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…
