One-way propagation of light in Born-Infeld-like metamaterials
Vitorio A. De Lorenci, Jonas P. Pereira
We propose and investigate a family of nonlinear metamaterials in which light rays propagate just in one direction -- one-way propagation. Furthermore, we argue how such nonlinear…
Decoherence induced by long wavelength gravitons
V. A. De Lorenci, L. H. Ford
We discuss how a background bath of gravitons can induce decoherence of quantum systems. The mechanism is dephasing, the loss of phase coherence due to quantum geometry fluctuation…
Local thermal behaviour of a massive scalar field near a reflecting wall
V. A. De Lorenci, L. G. Gomes, E. S. Moreira
The mean square fluctuation and the expectation value of the stress-energy-momentum tensor of a neutral massive scalar field at finite temperature are determined near an infinite p…
Vacuum Lightcone Fluctuations in a Dielectric
C. H. G. Bessa, V. A. De Lorenci, L. H. Ford +1
A model for observable effects of electromagnetic vacuum fluctuations is presented. The model involves a probe pulse which traverses a slab of nonlinear optical material with a non…
Quantum Brownian motion near a point-like reflecting boundary
V. A. De Lorenci, E. S. Moreira, M. M. Silva
The Brownian motion of a test particle interacting with a quantum scalar field in the presence of a perfectly reflecting boundary is studied in (1 + 1)-dimensional flat spacetime.…
An Analog Model for Light Propagation in Semiclassical Gravity
C. H. G. Bessa, V. A. De Lorenci, L. H. Ford
We treat a model based upon nonlinear optics for the semiclassical gravitational effects of quantum fields upon light propagation. Our model uses a nonlinear material with a nonzer…
Analogue black holes for light rays in static dielectrics
E. Bittencourt, V. A. De Lorenci, R. Klippert +2
Propagation of light in nonlinear materials is here studied in the regime of the geometrical optics. It is shown that a spherically symmetric medium at rest with some specific diel…
