A faster scaling in acceleration-sensitive atom interferometers

McDonald, Gordon; Noschang Kuhn, Carlos; Bennetts, Shayne; Debs, John; Hardman, Kyle; Close, John; Robins, Nicholas


Atom interferometers have been used to measure acceleration with at best a T2 scaling in sensitivity as the interferometer time T is increased. This limits the sensitivity to acceleration which is theoretically achievable by these configurations for a given frequency of acceleration. We predict and experimentally measure the acceleration-sensitive phase shift of a large-momentum-transfer atom interferometer based upon Bloch oscillations. Using this novel interferometric scheme we demonstrate an...[Show more]
