Applications of Bose-Einstein-Condensates in microgravity — •Hauke Müntinga1 und das QUANTUS Team1,2,3,4,5,6 — 1ZARM, Universität Bremen — 2Institut für Quantenoptik, LU Hannover — 3Institut für Physik, HU Berlin — 4Institut für Laserphysik, Universität Hamburg — 5Institut für Quantenphysik, Universität Ulm — 6MPQ, München
We report on the current status of the QUANTUS free fall BEC experiment at the ZARM drop tower in Bremen.
After the first realization of a BEC in microgravity in 2007, we were able to observe condensates after 1 s of free evolution. The extremely shallow traps possible in microgravity and resulting ultralow temperatures of a few nK allow for further studies ranging from coherence properties of condensates to inertial sensors based on matter waves.
In our talk we will focus on the implementation of a matter wave interferometer into our apparatus, which aims to extend measurement times to unprecedented durations and sensitivities, and therefore leads the way to future experiments on other microgravity platforms like sounding rockets and the ISS. These goals are worked on in close cooperation with QUEST and the PRIMUS project.
The QUANTUS project is a collaboration of U Hamburg, U Ulm, HU Berlin, MPQ Munich, ZARM at U Bremen and LU Hannover. It is supported by the German Space Agency DLR with funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number DLR 50WM0836.
