Diffractive focusing of a uniform Bose-Einstein condensate
Patrick Boegel, Matthias Meister, Jan-Niclas Siemß +3
We propose a straightforward implementation of the phenomenon of diffractive focusing with uniform atomic Bose-Einstein condensates. Both, analytical as well as numerical methods n…

Universal Atom Interferometer Simulator -- Elastic Scattering Processes
Florian Fitzek, Jan-Niclas Siemß, Stefan Seckmeyer +4
In this article, we introduce a universal simulator covering all regimes of matter wave light-pulse elastic scattering. Applied to atom interferometry as a study case, this simulat…

Analytic theory for Bragg atom interferometry based on the adiabatic theorem
Jan-Niclas Siemß, Florian Fitzek, Sven Abend +3
High-fidelity Bragg pulses are an indispensable tool for state-of-the-art atom interferometry experiments. In this paper, we introduce an analytic theory for such pulses. Our theor…
