Werner, Michael — Phase shifts of atom interferometers in curved PPN-spacetimes

I will present a systematic approach to calculate the phase shifts associated to a variety of different interferometer geometries in a curved PPN spacetime. This spacetime geometry is a generalization of Einsteins GR and therefore may give rise to novel quantum tests of relativity. The whole analysis is done in a fashion, which is easy adaptable to different experimental setups. The role of time and different coordinate charts is discussed in more detail, since potential errors can arise quite quickly, when certain relativistic principles are not thought of and calculations are done in „the usual manner“ – with potentially measurable deviances.
