  "abstract": "We present a quantum theory of slow light beyond the weak probe pulse approximation. By reduction of the full Hamiltonian of the system to an effective Hamiltonian for a single quantum field we demonstrate that the concept of dark-state polaritons can be introduced even if the linearized approach is no longer valid. The developed approach allows us to study the evolution of non-classical quantum states of the polariton field.",

      "abstract": "We study the properties of slow light propagating under the electromagnetically induced transparency condition in a medium consisting of a mesoscopic number of atoms (~100). This system can be mapped onto the generalized Tavis-Cummings model. The exact diagonalization of the latter's Hamiltonian yields the spectrum of dark polaritons. These fully quantum results are found to be in a good agreement with the mean-field approach.",
