In the late 20th century progress in the coherent manipulation of atoms enabled the use of atom interferometers for high-precision measurements [1,2]. They play a central role in state-of-the-art clocks, inertial sensors and gravimeters.
Our talk provides a compact and versatile description of matter wave interferometry solely based on operator algebra. We present a straightforward method for determining the phase-shift for general multi-loop interferometers taking into account the local gravitational acceleration, gravity gradient and rotation of the device.
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.
