Closed-time-path approach to the optomechanical back-reaction problem
Salvatore Butera
We present a perturbative closed-time-path (in-in) formulation of an optomechanical system in which a quantum field interacts with a moving mirror via radiation pressure. We derive…

Corrections to the Optomechanical Hamiltonian from Quadratic Fluctuations of a Moving Mirror
Salvatore Butera
We extend the theory of the radiation pressure to include quadratic fluctuations in the position of a moving mirror. This enables the introduction of a generalized radiation pressu…
