Atom interferometers in weakly curved spacetimes: Case study of the VLBAI — •Michael Werner and Klemens Hammerer — Institut für Theoretische Physik, Leibniz Universität Hannover, Appelstraße 2, 30167 Hannover, Germany

We present a systematic approach to determine all relevant phases in the VLBAI (Very Long Baseline Atom Interferometer) experiment in Hannover, including (general-) relativistic effects and certain noise sources. Through this approach, we automate the derivation of algebraic expressions for all relevant phases and analyze the impact of mitigation strategies, spanning from the Coriolis effect to gravity gradients. Our objective is to enhance the precision of experiments performed in the VLBAI facility and deepen our understanding of the physics inside such a large scale setup for the detection of relativistic effects.
