The near resonant interaction of light fields with three-level atoms involving a Rydberg state under conditions of electromagnetically induced transparency (EIT) can be described in terms of strongly interacting quasi-particles, termed Rydberg polaritons. An effective many-body model for dark and bright Rydberg polaritons is introduced and compared to recent experiments. The low energy physics of a 1D gas of dark Rydberg polaritons is discussed in terms of a Luttinger liquid model and numerical DMRG simulations. The generation of non-classical photon states with e.g. sub-poissonian number statistics and long-range crystalline order is discussed.
