Quantum communication through a partially reflecting accelerating mirror

چکیده
Motivated by the fact that null-shell of a collapsing black hole can be described perfectly reflecting accelerating mirror, we investigate an extension this model to mirror semi-transparency and derive general implicit expression for corresponding Bogoliubov coefficients. Then, turn into explicit analytical form focusing on mirrors are accelerated via impulsive force. From so-obtained coefficients particle production. Finally, realize field coming from left-past spacetime region, passing through semitransparent moving ending up right-future region as undergoing action Gaussian quantum channel. We study transmission noisy generation properties channel, relating them mirror's motion, which evaluate capacities in transmitting classical information.

Quantum radiation from a partially reflecting moving mirror
We consider the quantum radiation from a partially reflecting moving mirror for the massless scalar field in 1+1 Minkowski space. Partial reflectivity is achieved by localizing a δ-type potential at the mirror’s position. The radiated flux is exactly obtained for arbitrary motions as an integral functional of the mirror’s past trajectory. Partial reflectivity corrections to the perfect mirror r...
متن کاملct 1 99 9 Dynamical mass shift for a partially reflecting moving mirror NISTOR NICOLAEVICI
We consider the vacuum fluctuations contribution to the mass of a mirror in an exactly soluble partially reflecting moving mirror model. Partial reflectivity is accounted for by a repulsive delta-type potential localized along the mirror’s trajectory. The mirror’s mass is explicitly obtained as an integral functional of the mirror’s past trajectory.
متن کاملDouble Relativistic Electron Accelerating Mirror
In the present paper, the possibility of generation of thin dense relativistic electron layers is shown using the analytical and numerical modeling of laser pulse interaction with ultra-thin layers. It was shown that the maximum electron energy can be gained by optimal tuning between the target width, intensity and laser pulse duration. The optimal parameters were obtained from a self-consisten...
متن کاملLandscape mirror: the attractiveness of reflecting water
This research examined human preference for water and a key aspect of water, its reflection. We compared responses to reflection in water versus reflection in glass and responses to reflection versus transparency. Sixty respondents rated the attractiveness of four scale-models varied on those dimensions. High inter-item reliability across the rating scales called for their combination into a co...
