    • We assume that the position of the central lattice site corresponds to the center of expansion. In practice the position of the central lattice site will depend on the relative phase of the lattice beams

    • We have also calculated the ground-state probability for one set of parameters in two dimensions to verify that ignoring the dynamics along the direction perpendicular to motion does not introduce significant errors
