Light-pulse atom interferometers have become an instrument for high-precision measurements of accelerations and rotations by determining the phase difference between two branches of the interferometer. Efficient calculation schemes are required to predict and investigate experimental results.
In our contribution we focus on the influence of time- and space-dependent potentials on atom interferometers. We present a numerical method based on comoving frames along each branch to efficiently calculate the impact of an arbitrary potential on the propagation of atomic wave packets in an atom interferometer.
