2 Jun 1999 | | Subject: | cond-mat | | Abstract: | We study the coherence properties of an atom laser, which operates by extracting atoms from a gaseous Bose-Einstein condensate via a two-photon Raman process, by analyzing a recent experiment. We obtain good agreement with the experimental data by solving the time-dependent Gross-Pitaevskii equation in three dimensions both numerically and with a Thomas-Fermi model. The coherence length is strongly affected by the space-dependent phase developed by the condensate when the trapping potential is turned off. | | Source: | arXiv, cond-mat/9906033 | | Services: | Forum | Review | PDF | Favorites | |
