    "abstract": "The many-particle spectrum of an isotropic frequency gap medium doped with\nimpurity resonance atoms is studied using the Bethe ansatz technique. The\nspectrum is shown to contain pairs of quantum correlated ``gap excitations\u0027\u0027\nand their heavy bound complexes (``gap solitons\u0027\u0027), enabling the propagation of\nquantum information within the classically forbidden gap. In addition,\nmultiparticle localization of the radiation and the medium polarization occurs\nwhen such a gap soliton is pinned to the impurity atom.",
