@article{Dubetsky2016AtomII, title={Atom interferometry in the presence of an external test mass}, author={B. Ya. Dubetsky and Stephen B. Libby and P. R. Berman}, journal={arXiv: Atomic Physics}, year={2016} }

The influence of an external test mass on the phase of the signal of an atom interferometer is studied theoretically. Using traditional techniques in atom optics based on the density matrix equations in the Wigner representation, we are able to extract the various contributions to the phase of the signal associated with the classical motion of the atoms, the quantum correction to this motion resulting from atomic recoil that is produced when the atoms interact with Raman field pulses, and…
