“…In equation ( 70), q− n , p− n are the initial amplitude and conjugate momentum of the field's modes, respectively. In equation ( 71) instead, G − n (t) = θ(t)g − n (t) with g − n (t) = sin(ω n t)/ω n , is the retarded Green function for equation (68), with vanishing initial conditions. By using equations ( 69)-( 71), the equation governing the time evolution of the idf, that includes the back-reaction from the field, takes the form:…”

“…Such decoherence effects are responsible for driving the quantum-to-classical transition of any macroscopic objects interacting with light [64]. Pioneering theoretical works pushed these studies towards more complex configurations, proving vacuum mediated coherent exchange of excitations at the single phonons level between physically separated mirrors [65,66] and between mirrors and atoms [67], as well as photons hopping induced by mechanical zero-point fluctuations [68] in optomechanical lattices [69].…”

We adopt an open quantum system approach to study the effects of the back-reaction from a quantum field onto the dynamics of a moving mirror. We describe the coupling between the mirror and the field by using a microscopic model from which the dielectric response of the mirror is obtained from first principles. Using second-order perturbation theory, we derive the master equation governing the mechanical motion of the mirror. Our analysis reveals that the mirror experiences coloured noise and non-local dissipation, which originate from the emission of particle pairs via the dynamical Casimir effect. We show that the noise and dissipation kernels, that enter in the definition of the time-dependent coefficients of the master equation, are related by standard fluctuation-dissipation relations.
