The field of light-pulse atom interferometers has made an enormous progress in precision with a wealth of applications since the first experiments 25 years ago. Improving the resolution by means of longer interferometer times is, however, accompanied by a loss in the signal-to-noise ratio because of the decreasing density of the cloud. Although atomic lensing (also known as delta-kick cooling) can mitigate this problem (see Ref. [1], for instance), we illustrate that possible “lens aberrations” caused by potential anharmonicities can give rise to non-trivial features of the atomic cloud [2]. In particular, we investigate their relevance in the context of recent QUANTUS and future high-precision experiments.
The QUANTUS project is supported by the German Space Agency DLR with funds provided by the Federal Ministry for Economic Affairs and Energy (BMWi) under grant number 50WM1556.
