Dispersive interaction between two atoms in Proca quantum electrodynamics

Physical Review D
We analyze the influence of a massive photon in the dispersive interaction between two atoms in their fundamental states. We work in the context of Proca quantum electrodynamics. The photon mass not only introduces a new length scale but also gives rise to a longitudinal polarization for the electromagnetic field.

Probing atom-surface interactions with an atomic quantum sensor

This thesis presents the first force measurements at close range between an atom and a surface, which was the ultimate objective of the Forca-G project. The force is measured by atom interferometry with atoms trapped in potential wells formed by a vertical optical lattice.
