Abstract

Matter-wave interferometers show great a potential for improving inertial sensing. The absence of drifts recommends them for a variety of applications in geodesy, navigation, or fundamental physics. Atom interferometry offers an interesting perspective for the detection of gravitational waves in the frequency band between eLISA and Advanced LIGO. A key feature to reach the targeted sensitivities for these devices is large momentum transfer. Optical lattices are ideal tools to transfer large number of photon recoils onto atoms for interferometry. We demonstrate twin-lattice atom interferometers with up to 1632 photon recoils at a maximum splitting of 408 photon recoils. To reach these large momentum splittings while maintaining interferometric contrast, we utilize delta-kick collimated Bose-Einstein condensates generated on an atom-chip. Twin-lattice interferometers might open up new perspective for a variety of applications using compact atom interferometer geometries.
