Bose-Einstein-condensate interferometer with macroscopic arm separation
- 1. Physics Department, University of Virginia, Charlottesville, Virginia 22904 (United States)
Description
A Michelson interferometer using Bose-Einstein condensates is demonstrated with coherence times of up to 44 ms and arm separations up to 180 μm. This arm separation is larger than that observed for any previous atom interferometer. The device uses atoms weakly confined in a magnetic guide and the atomic motion is controlled using Bragg interactions with an off-resonant standing-wave laser beam
