Atom interferometry using wavepackets with constant spatial displacements
Edward J. Su, Saijun Wu, Mara Prentiss
Abstract
We demonstrate a standing wave light pulse sequence that places atoms into a superposition of displaced wavepackets with precisely controlled displacements that remain constant for times as long as 1 s. The separated wavepackets are subsequently recombined resulting in atom interference patterns that probe energy differences of approximately 10-34 J, and can provide acceleration measurements that are insensitive to platform vibrations.
