Query: Cavity-Assisted Back Action Cooling of Mechanical Resonators   We analyze the quantum regime of the dynamical backaction cooling of a
mechanical resonator assisted by a driven harmonic oscillator (cavity). Our
treatment applies to both optomechanical and electromechanical realizations and
includes the effect of thermal noise in the driven oscillator. In the
perturbative case, we derive the corresponding motional master equation using
the Nakajima-Zwanzig formalism and calculate the corresponding output spectrum
for the optomechanical case. Then we analyze the strong optomechanical coupling
regime in the limit of small cavity linewidth. Finally we consider the steady
state covariance matrix of the two coupled oscillators for arbitrary input
power and obtain an analytical expression for the final mechanical occupancy.
This is used to optimize the drive's detuning and input power for an
experimentally relevant range of parameters that includes the "ground state
cooling" regime.
