Abstract
A 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 approximate to 10(-34) J and can provide acceleration measurements that are insensitive to platform vibrations.
