    "abstract": "We report an experimental study of quantum transport for atoms confined in a\nperiodic potential and compare between thermal and BEC initial conditions. We\nobserve ballistic transport for all values of well depth and initial\nconditions, and the measured expansion velocity for thermal atoms is in\nexcellent agreement with a single-particle model. For weak wells, the expansion\nof the BEC is also in excellent agreement with single-particle theory, using an\neffective temperature. We observe a crossover to a new regime for the BEC case\nas the well depth is increased, indicating the importance of interactions on\nquantum transport.",
