Evaporation and expansion of ultracold gases calculated on GPUs — •Roman Nolte — TU Darmstadt

Evaporative cooling is the essential method for attaining quantum degeneracy. In the Quantus experiment [1], which explores quantum gases in microgravity the details of this process are of greater interest due to limited time. As the experiment itself also investigates and utilizes the expansion properties their theoretical description becomes of interest too.

In this contribution we present the predictions of our N-particle molecular dynamics simulation performed on graphic cards both describing evaporation and free expansion properties of ultracold gases and compare them to the results of the aforementioned experiment.
