Interferences in the density of two initially independent Bose-Einstein condensates

Other Condensed Matter 2007-05-23 v2

Abstract

It is shown that the density of two {\it initially independent} condensates which are allowed to expand and overlap can show interferences as a function of time due to interparticle interaction. Using many-body theory, explicit expressions for the density are given which are exact in the weak interaction limit. General working equations are discussed which reproduce exactly the density in this limit. Illustrative examples are presented.
