Abstract : Values of both atomic and photon quasiparticle excitation energies and lifetimes are calculated for the model of a dilute gas of two-level atoms interacting with the electromagnetic modes of a macroscopic enclosure. Interactions both linear and quadratic in the magnetic vector potential are included. Failure to make the rotating wave approximation leads directly to pairing in the system, hole-electron pairing in the atoms, photon-photon pairing in the electromagnetic modes. The pairing properties of the ground state of the interacting system are exhibited explicitly. First-and second-order intensity correlation functions are calculated for the ground state. (Author)
