  The quantum dynamics of a dense and dipole-dipole coupled ensemble of
two-level emitters interacting via their environmental thermostat is
investigated. The static dipole-dipole interaction strengths are being
considered strong enough but smaller than the transition frequency. Therefore,
the established thermal equilibrium of ensemble's quantum dynamics is described
with respect to the dipole-dipole coupling strengths. We have demonstrated the
quantum nature of the spontaneously scattered light field in this process for
weaker thermal baths as well as non-negligible dipole-dipole couplings compared
to the emitter's transition frequency. Furthermore, the collectively emitted
photon intensity suppresses or enhances depending on the environmental thermal
baths intensities.
