Abstract
We investigate the vibrational dynamics of a quantum mechanical
resonator when an ensemble of laser pumped two-level emitters are fixed on
it.
Beyond the rotating wave approximation with respect to phonon's variables one
can obtain an interesting phonon quantum dynamics if the
quantum emitter's variables are faster than those describing the mechanical
resonator. Particularly, for certain parameters one can obtain an
enhanced phonon emission as well as larger phonon-phonon correlations in the
steady-state.
