The enormous progress in the coherent manipulation of atoms has enabled the use of atom interferometers for high-precision measurements [1,2]. They play a central role in the implementation of clocks, inertial sensors and gravimeters.
Our talk focuses on matter-wave interferometers embedded in non-inertial reference frames necessary for the
description of state-of-the-art space missions.
We show that effects due to non-inertial reference frames can be easily interpreted when the general coordinate
transformation is decomposed into elementary ones. In particular, the transformation into a rotating frame modifies
the ordinary Sagnac terms.
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.
