Coherent Control of Atomic Dynamics by Non-classical Light

In this paper we consider the mechanism of coherent control of atomic collisions by two-photon excitation of colliding atoms with nonclassical light characterized by polarization entanglement. Such modification of the well-known optical-collision method is proposed as a possible spectroscopic application of nonclassical light for study of collisional dynamics. We show that quantum correlations allow one to have a deeper control of the internal dynamics of atomic collision than do the principles of classical statistics. Our qualitative discussion is supported by numerical calculations made for ${}^{1}{S}^{1}{P}^{1}S$ optical transition of Mg perturbed by collisions with rare-gas atom.In this paper we consider the mechanism of coherent control of atomic collisions by two-photon excitation of colliding atoms with nonclassical light characterized by polarization entanglement.
