Spatially entangled atomic deflections in twin-photon light beams
Gagik Yu. Kryuchkyan, Mihai Macovei, Christoph H. Keitel · Physical Review A · 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.
