We present a numerical simulation of the double slit interference experimentrealized by F. Shimizu, K. Shimizu and H. Takuma with ultracold atoms. We showhow the Feynman path integral method enables the calculation of thetime-dependent wave function. Because the evolution of the probability densityof the wave packet just after it exits the slits raises the issue of theinterpreting the wave/particle dualism, we also simulate trajectories in the deBroglie-Bohm interpretation.
