Phys. Rev. A 79, 043630 (2009) [6 pages]Atom interferometry using Kapitza-Dirac scattering in a magnetic trapReceived 28 October 2008; published 28 April 2009 We demonstrate two atom interferometric schemes based on Kapitza-Dirac scattering in a magnetic trap. In the first method, two Kapitza-Dirac scattering pulses are applied with a small time delay between them. High contrast interference is observed both using a thermal cloud and a Bose-Einstein condensate (BEC). In the second method, two Kapitza-Dirac scattering pulses are applied to a BEC with a time separation sufficiently large that the interfering orders complete half an oscillation in the magnetic trap; this enables interferometry between spatially separated paths. © 2009 The American Physical Society URL:
