Query: Limiting effects of geometrical and optical nonlinearities on the
  squeezing in optomechanics   In recent experiments, the re-thermalization time of the mechanical resonator
is stated as the limiting factor for quantum applications of optomechanical
systems. To explain the origin of this limitation, an analytical nonlinear
investigation supported by the recent successful experimental laser cooling
parameters is carried out in this work. To this end, the effects of geometrical
and the optical nonlinearities on the squeezing are studied and are in a good
agreement with the experimental results. It appears that highly squeezed state
are generated where these nonlinearities are minimized and that high
nonlinearities are limiting factors to reach the quantum ground state.
