Role of interactions in time-of-flight expansion of atomic clouds from optical lattices

Joern N. Kupferschmidt, Erich J. Mueller

Published 2010-06-10, updated 2010-08-02Version 2

We calculate the effect of interactions on the expansion of ultracold atoms from a single site of an optical lattice. We use these results to predict how interactions influence the interference pattern observed in a time of flight experiment. We find that for typical interaction strengths their influence is negligible, yet that they reduce visibility near a scattering resonance.
