    "abstract": "We study quantum effects of light propagation through an extended absorbing\nsystem of two-level atoms placed within a frequency gap medium (FGM). Apart\nfrom ordinary solitons and single particle impurity band states, the\nmany-particle spectrum of the system contains massive pairs of confined gap\nexcitations and their bound complexes - gap solitons. In addition,\n``composite\u0027\u0027 solitons are predicted as bound states of ordinary and gap\nsolitons. Quantum gap and composite solitons propagate without dissipation, and\nshould be associated with self-induced transparency pulses in a FGM.",
