Influence of external forces in near-field matter-wave interferometry — •Filip Kiałka, Benjamin Stickler, and Klaus Hornberger — Faculty of Physics, University of Duisburg-Essen, Lotharstraße 1-21, 47048 Duisburg, Germany

Molecular matter-wave interferometry is an established experimental technique with applications in precision metrology and fundamental quantum science [1]. In this work, we analyze the interference pattern observed in a generic Talbot-Lau interferometer (TLI) subject to external forces. In particular, we study the influence of the Coriolis force, which will become significant for interferometers with long flight times. We quantify the loss of interference contrast and explore the strategies to correct for the Coriolis effect in a TLI setup. Finally, we examine how the external force exerted by an electric field with a constant gradient could be used for metrological purposes.
