Our BEC experiment at the ZARM Droptower aims to realise high precision interferometric measurements with matter waves. In order to exploit the advantage of long expansion times in a microgravity environment, a high degree of control and a detailed understanding of the dynamics during preparation are needed. For this purpose a detailed model of the atom-chip-based experiment has been developed and helps in designing optimized experimental sequences. These simulations allow for investigating the high potential of quantum gases in microgravity for new and challenging experiments.
The QUANTUS project is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number DLR 50WM0835-0839.
