    "abstract": "Starting from the first principles of nonrelativistic QED we have developed\nthe quantum theory of the interaction of a two-component ultracold atomic\nensemble with the electromagnetic field of vacuum and laser photons. The main\nattention has been paid to the consistent consideration of dynamical\ndipole-dipole interactions in the radiation field. Taking into account\nlocal-field effects we have derived the system of Maxwell-Bloch equations.\nOptical properties of the two-component Bose gas are investigated. It is shown\nthat the refractive index of the gas is given by the Maxwell-Garnett formula.\nAll equations which are used up to now for the description of the behavior of\nan ultracold atomic ensemble in a radiation field can be obtained from our\ngeneral system of equations in the low-density limit. Raman-Nath diffraction of\nthe two-component atomic beam is investigated on the basis of our general\nsystem of equations.",
