Atom Interferometry in Gravity — •Endre Kajari, Gerrit Nandi, Reinhold Walser, and Wolfgang P. Schleich — Institut für Quantenphysik, Universität Ulm, 89069 Ulm, Germany

In the seminal atomic fountain experiment A. Peters, K. Y. Chung and S. Chu [1,2] measured the gravitational acceleration with very high accuracy. Since this time many activities for gravitational, rotational and inertial sensing with matter waves have been initiated, e. g. MAGIA, CASI and HYPER. This talk introduces an efficient theoretical description of such matter wave interferometric devices. In particular, we analyze the dependence of the phase difference on several experimental parameters, such as the time delay between the laser pulses or changes of the laser frequencies to compensate for Doppler shifts.
