Abstract

At the Institute of Microproduction Technology of Leibniz University Hanover, in cooperation with the Institute of Quantum Optics, atom chips are developed and manufactured which are part of a magneto-optical trap (MOT) for compact matter wave interferometers. In the past, first investigations in the laboratory and under real conditions have been successfully performed. For this purpose, the first Bose-Einstein-Condensate (BEC), which is necessary for matter wave interferometry, was generated in the QUANTUS project [1]. The follow-up project QUANTUS-2 led to a miniaturization of the setup and to testing in drop tower experiments [2]. With the knowledge gained, a BEC was generated in space and detected and characterized by means of atomic interference as part of the MAIUS-1 mission [3]. These high-precision matter-wave interferometers offer advantages over classical laser interferometers in terms of measurement precision, reproducibility, and obsoleteness of calibration and maintenance. Due to the stationary design and the high complexity, the use for commercial purposes is made difficult. This requires fiarther miniaturization and integration of the overall system.
