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…
