Abstract

An exact steady-state density operator is obtained for a model describing the collective behaviour of a system of N two-level atoms. The model yields a Fokker-Planck equation which does not satisfy detailed balance. The density operator is further employed to obtain exact analytical expressions for steady-state expectation values of the collective atomic operators both for finite N and in the thermodynamic limit N → ∞.
