1D Bose gases in an optical lattice

We report on the study of the momentum distribution of a one-dimensional Bose gas in an optical lattice. From the momentum distribution we extract the condensed fraction of the gas and thereby measure the depletion of the condensate and compare it with a theoretical estimate. We have measured the co...

Zusammenfassung:We report on the study of the momentum distribution of a one-dimensional Bose gas in an optical lattice. From the momentum distribution we extract the condensed fraction of the gas and thereby measure the depletion of the condensate and compare it with a theoretical estimate. We have measured the coherence length of the gas for systems with average occupation {/content/G5TFAD7VTML6110W/xxlarge110_772.gif}>1 and {/content/G5TFAD7VTML6110W/xxlarge110_772.gif}
