Query: Steady-state mechanical squeezing in a double-cavity optomechanical
  system   We study the physical properties of double-cavity optomechanical system in
which the mechanical resonator interacts with one of the coupled cavities and
another cavity is used as an auxiliary cavity. The model can be expected to
achieve the strong optomechanical coupling strength and overcome the
optomechanical cavity decay, simultaneously. Through the coherent auxiliary
cavity interferences, the steady-state squeezing of mechanical resonator can be
generated in highly unresolved sideband regime. The validity of the scheme is
assessed by numerical simulation and theoretical analysis of the steady-state
variance of the mechanical displacement quadrature. The scheme provides a
platform for the mechanical squeezing beyond the resolved sideband limit and
addresses the restricted experimental bounds at present.
