Molecular dynamics of trapped cold gases on GPUs — •Roman Nolte and Reinhold Walser — Institut für Angewandte Physik, Technische Universität Darmstadt

The understanding of classical molecular dynamics of N rapped interacting atoms is an important precursor in order to achieve quantum degeneracy. In the QUANTUS experiment, which explores quantum gases in microgravity in the ZARM droptower in Bremen, the evaporation time is a scarce resource. It is therefore of critical importance to understand the non-equilibrium dynamics with high precision.

In this contribution we present results of N-particle 3D molecular dynamics simulation performed on graphic cards (GPU). We investigated the dependence of relaxation on external parameters and the validity of common assumptions.
