Abstract

We demonstrate a spatially resolved autocorrelation measurement with a Bose-Einstein condensate (BEC) and measure the evolution of the spatial profile of its quantum mechanical phase. After releasing the BEC from the magnetic trap, the phase develops a quadratic form which we measure. Our experiments reveal the effects of the repulsive interaction between two overhapping BEC wavepackets and we measure the small momentum they impart to each other.
