Phys. Rev. A 77, 035603 (2008) [4 pages]Spatially entangled atomic deflections in twin-photon light beamsReceived 23 August 2007; revised 23 January 2008; published 20 March 2008 We investigate deflections, spatial entanglement, and localization of an atomic beam due to its interaction with two modes of a standing electromagnetic field in an optical cavity. It is demonstrated that the deflection properties of an atom passing through two crossed standing light waves are crucially modified when photon-number correlated states of light are used instead of independent waves. Depending on the atom-light interaction scheme, various periodic two-dimensional patterns in a subwavelength regime are reported. © 2008 The American Physical Society URL:
