Dark matter or violations of the Einstein equivalence principle influence motion atoms, their internal states as well electromagnetic fields, thus causing a signature in signal atomic detectors. To model such new physics, we introduce dilaton fields and study modified propagation light used to manipulate atoms light-pulse atom interferometers. Their interference is dominated by matter's couplin...

In an atom interferometry experiment, the output phase shift depends on wave vector of photons and recoil momentum in optical transitions. This Letter puts forward a hypothesis that light-atom interaction, function could provide transverse confinement to thus affect mean momentum. We propose model analyze photon effective monochromatic field calculate relative $|{\stackrel{\ensuremath{\rightarr...

For the astronomer, x-ray interferometry is the theory and practice of building dilute aperture telescopes for studying celestial x-ray sources. The short wavelengths and high surface brightness of x-ray sources will make the eventual scientific payoff very high, with direct imaging of the event horizons of black holes as the centerpiece. In this article we review the history of x-ray interfero...
