Title: Interference of a variable number of coherent atomic sources

Abstract

We have studied the interference of a variable number of independently created m{sub F}=0 microcondensates in a CO{sub 2}-laser optical lattice. The observed average interference contrast decreases with condensate number N. Our experimental results agree well with the predictions of a random walk model. While the exact result can be given in terms of Kluyver's formula, for a large number of sources a 1/{radical}(N) scaling of the average fringe contrast is obtained. This scaling law is found to be of more general applicability when quantifying the decay of coherence of an ensemble with N independently phased sources.
