Representation-free description of light-pulse atom interferometry including non-inertial effects — •Stephan Kleinert, Endre Kajari, Albert Roura, Wolfgang P. Schleich, and the QUANTUS Team — Institut für Quantenphysik and Center for Integrated Quantum Science and Technology (IQST), Universität Ulm
The coherent manipulation of atoms by laser pulses enables the use of atom interferometers for gravimetry and inertial sensing, accurate measurements of fundamental constants and tests of fundamental properties.
Here we provide a versatile representation-free description of atom interferometry including the effects of
quadratic external potentials (e. g. due to gravity gradients) as well as arbitrary time-dependent accelerations and
rotations [1]. In particular, our approach can easily model interferometers embedded in non-inertial reference frames
necessary for microgravity experiments in drop-tower facilities, sounding rockets or dedicated
satellite missions.
The QUANTUS project is supported by the German Space Agency (DLR) with
funds provided by the Federal Ministry of Economics and Technology (BMWi) under grant number 50WM1136.
