Title: Non-Gaussian two-mode squeezing and continuous-variable entanglement of linearly and circularly polarized light beams interacting with cold atoms

Abstract: We investigate how entangled coherent states and superpositions of low intensity coherent states of non-Gaussian nature can be generated via nonresonant interaction between either two linearly or circularly polarized field modes and an ensemble of X-like four-level atoms placed in an optical cavity. We compare our results to recent experimental observations and argue that the non-Gaussian structure of the field states may be present in those systems.
