Second-Order Processes in Emission of Radiation by an Ensemble of Quantum Oscillators

It is shown that in the local approach to analysis of open oscillator systems, in the presence of a common boson thermostat in an ensemble of identical quantum oscillators, collective emission of radiation by the oscillator ensemble demonstrates features of the non-Wiener dynamics. The intensity of radiation emitted by large number N-c of oscillators in the ensemble decreases with increasing N-c and turns out periodically to be completely suppressed by second-order processes in the constant of coupling of the oscillators with the common thermostat field.
