Demonstration of interferometric atom-pattern engineering via Rabi oscillations

We report an experimental demonstration of atom-pattern engineering via Rabi oscillations. We make use of interferometric Raman beams to drive a microwave transition for laser-cooled atoms confined within an optical dipole trap. Up to nine fringes are patterned within a half wavelength of the Raman standing wave. We also demonstrate spatial atom localization by using two Raman pulses together with optical depletion. Our work may be useful in atom-pattern engineering for quantum information and simulation applications.
