Proper time in atom interferometers: Diffractive versus specular mirrors

authored by: Enno Giese, Alexander Friedrich, Fabio Di Pumpo, Albert Roura, Wolfgang P. Schleich, Daniel M. Greenberger, Ernst M. Rasel
Abstract: We compare a conventional Mach-Zehnder light-pulse atom interferometer based on diffractive mirrors with one that uses specular reflection. In contrast to diffractive mirrors that generate a symmetric configuration, specular mirrors realized, for example, by evanescent fields lead under the influence of gravity to an asymmetric geometry. In such an arrangement the interferometer phase contains nonrelativistic signatures of proper time.
