Casimir Energy Corrections by Light-Cone Fluctuations
E. Arias, C. H. G. Bessa, J. G. Dueñas +2
We study the effects of light-cone fluctuations on the renormalized zero-point energy associated with a free massless scalar field in the presence of boundaries. In order to simula…
Relativistic Bose-Einstein condensation with disorder
E. Arias, G. Krein, G. Menezes +1
We investigate the thermodynamics of a self-interacting relativistic charged scalar field in the presence of weak disorder. We consider quenched disorder which couples linearly to…
Thermal Radiation from a Fluctuating Event Horizon
E. Arias, G. Krein, G. Menezes +1
We consider a pointlike two-level system undergoing uniformly accelerated motion. We evaluate the transition probability for a finite time interval of this system coupled to a mass…
An analog fluid model for some tachyonic effects in field theory
E. Arias, C. H. G. Bessa, N. F. Svaiter
We consider the sound radiation from an acoustic point-like source moving along a supersonic ("space-like") trajectory in a fluid at rest. We call it an acoustic "tachyonic" source…
Scalar Quantum Field Theory in Disordered Media
E. Arias, E. Goulart, G. Krein +2
A free massive scalar field in inhomogeneous random media is investigated. The coefficients of the Klein-Gordon equation are taken to be random functions of the spatial coordinates…
The Bekenstein Bound in Asymptotically Free Field Theory
E. Arias, N. F. Svaiter, G. Menezes
For spatially bounded free fields, the Bekenstein bound states that the specific entropy satisfies the inequality , where stands for the radius of the sm…
