Wave packet dynamics of a Bose Einstein Condensate in a one dimensional, disordered potential for variable interaction strengths — •Juan Pablo Ramírez Valdes, Thomas Wellens, and Andreas Buchleitner — Physikalisches Institut, Albert-Ludwigs Universität Freiburg, Herman-Herder-Str. 3a, 79104 Freiburg, Germany

We study the impact of interactions on the wave packet dynamics of Bose Einstein condensates (BEC) in a one dimensional, disordered potential, with particular focus on the comparison between the regimes of localized and diffusive transport. In a first step, we develop a numerical method to effciently solve the time-dependent Gross-Pitaevskii equation (GPE) for Gauss-correlated disorder, and monitor the wave packet dynamics as a function of increasing interaction strength.
