Atom interferometry in microgravity on long time scales — Dorthe Leopoldt1, •Anurag Bhadane2, Merle Cornelius3, Laura Pätzold3, Julia Pahl4, Ernst Rasel1, and Quantus Team1,2,3,4,5,6 — 1LU Hannover — 2JGU Mainz — 3U Bremen — 4HU Berlin — 5U Ulm — 6TU Darmstadt
Atom interferometry allows for precise quantum sensors, which can e.g. be used to perform a quantum test of Einstein's equivalence principle. The QUANTUS-2 experiment enables rapid BEC production of Rb-87 with over 1e5 atoms and performs atom interferometry under extended free fall at the ZARM drop tower in Bremen. With that it serves as a testbed for future space-based missions. By applying a quadrupole mode enhanced magnetic lens, we are able to reduce the total kinetic energy of the BEC down to 3/2*k_B*38 pK in three dimensions in order to increase the ensemble's density. Here, we present the latest results on single species atom interferometry in QUANTUS-2 and our next steps, including the implementation of potassium.
The QUANTUS project is supported by the DLR with funds provided by the Federal Ministry for Economic Affairs and Climate Action under grant number DLR 50WM1952-1957.
