Double Bragg atom interferometry with Bose-Einstein condensates in microgravity — •Anurag Bhadane1, Dorthe Leopoldt2, Priyanka Barik2, Govindarajan Prakash3, Julia Pahl4, Sven Herrmann3, Andre Wenzlawski1, Sven Abend2, Markus Krutzik4,5, Patrick Windpassinger1, Ernst Rasel2, and The Quantus Team1,2,3,4,6,7 — 1JGU Mainz — 2LU Hannover — 3ZARM, U Bremen — 4HU Berlin — 5FBH Berlin — 6U Ulm — 7TU Darmstadt
The QUANTUS-2 device is a mobile, robust, high-flux atom interferometer utilizing 87Rb, designed for microgravity environments such as those provided by the Bremen drop tower and Gravitower. The Gravitower enables higher repetition rates for experiments, establishing QUANTUS-2 as a testbed for future space-based missions.
Our experiment employs a magnetic lens via the quadrupole field of an atom chip, achieving extended coherence times and enabling interferometry durations exceeding one second with double Bragg diffraction under microgravity conditions. On this poster, we report recent advancements in atom interferometry at extended timescales, along with the characterization of the system in the Gravitower.
This project is supported by the German Space Agency DLR with funds provided by the Federal Ministry for Economic Affairs and Climate Action under grant numbers DLR 50WM1952-1957 and DLR 50 WM 2450A-F
