Atom interferometry using wave packets with constant spatial displacements 81(4): 043631.1050-29471094-1622http://nrs.harvard.edu/urn-3:HUL.InstRepos:8951185A standing-wave light-pulse sequence is demonstrated that places atoms into a superposition of wave packets with precisely controlled displacements that remain constant for times as long as 1 s. The separated wave packets are subsequently recombined, resulting in atom interference patterns that probe energy differences of \(\approx10^{-34} J\) and can provide acceleration measurements that are insensitive to platform vibrations.en-USguiding neutral atomsmatter-wavetime-domainopticsJournal Article2012-07-0310.1103/PhysRevA.81.043631
