Query: Macroscopic tunneling of a membrane in an optomechanical double-well
  potential   The macroscopic tunneling of an optomechanical membrane is considered. A
cavity mode which couples quadratically to the membranes position can create
highly tunable adiabatic double-well potentials, which together with the high
Q-factors of such membranes render the observation of macroscopic tunneling
possible. A suitable, pulsed measurement scheme using a linearly coupled mode
of the cavity for the verification of the effect is studied.
