Title: Noise and dissipation on a moving mirror induced by the dynamical Casimir emission
Authors: Salvatore Butera
Abstract summary: We adopt an open quantum system approach to study the dynamics of a moving mirror. We derive the master equation governing the mechanical motion of the mirror. 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 fluctuation-dissipation relations.

Abstract: 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 fluctuation-dissipation relations.

We consider a real massless scalar field in 1+1 dimensions interacting with a moving $delta-deltaprime$ mirror with time-dependent properties. The asymmetry of the system is investigated by analyzing the difference in particle spectra produced on the two sides of the mirror.

Influence functional for two mirrors interacting via radiation pressure [0.0]
We study the effective dynamics of two mirrors, forming an optical cavity, and interacting with the cavity field via radiation pressure. We find that the quantum and thermal fluctuations of the cavity field result in coloured, Gaussian noises acting on the mirrors. To each of these noises is associated a dissipative effect, and the corresponding power spectra and susceptibilities are related via generalized-dissipation relations.

Quantum asymmetry and noisy multi-mode interferometry [55.41644538483948]
Quantum asymmetry is a physical resource which coincides with the amount of coherence between the eigenspaces of a generator. We show that the asymmetry may emphincrease as a result of a emphdecrease of coherence inside a degenerate subspace.

In spite of particle losses the quantum entanglement propagation exhibits a ballistic character with propagation speeds related to the differerent quasiparticles that are involved in the dynamics. Our analysis reveals that photon dissipation has a strikingly asymmetric behavior in the two configurations with a much more dramatic role on the holon entanglement propagation than for the doublon case.
