Hawking radiation from ultrashort laser pulse filaments
F. Belgiorno, S. L. Cacciatori, M. Clerici +6
Event horizons of astrophysical black holes and gravitational analogues have been predicted to excite the quantum vacuum and give rise to the emission of quanta, known as Hawking r…
Will the tachyonic Universe survive the Big Brake?
Zoltán Keresztes, László Á. Gergely, Alexander Yu. Kamenshchik +2
We investigate a Friedmann universe filled with a tachyon scalar field, which behaves as dustlike matter in the past, while it is able to accelerate the expansion rate of the unive…
Dark matter effects in vacuum spacetime
Luca Rizzi, Sergio Cacciatori, Vittorio Gorini +2
We analyze a toy model describing an empty spacetime in which the motion of a test mass (and the trajectories of photons) evidence the presence of a continuous and homogeneous dist…
Spacetime geometries and light trapping in travelling refractive index perturbations
F. Belgiorno, S. L. Cacciatori, V. Gorini +4
In the framework of transformation optics, we show that the propagation of a locally superluminal refractive index perturbation (RIP) in a Kerr medium can be described, in the eiko…
Dielectric black holes induced by a refractive index perturbation and the Hawking effect
F. Belgiorno, S. L. Cacciatori, G. Ortenzi +3
We consider a 4D model for photon production induced by a %superluminal refractive index perturbation in a dielectric medium. We show that, in this model, we can infer the presence…
