In this paper we analyze perturbatively a g phi^4 classical field theory with and without temperature. In order to do that, we make use of a path-integral approach developed some time ago for classic...
Attractors in Dark Energy Models with Born-Infeld Scalar Field
Dark Energy Models Born-Infeld Scalar Field
2010/10/15
We derive, in the large scale limit, analytical solutions for a dark energy model described by the Born-Infeld field plus a perfect fluid, both for homogeneous background and first order perturbations...
A Model for a Non-Minimally Coupled Scalar Field Interacting with Dark Matter
a Non-Minimally Coupled Scalar Field Dark Matter
2010/10/15
In this work we investigate the evolution of a Universe consisted of a scalar field, a dark matter field and noninteracting baryonic matter and radiation. The scalar field, which plays the role of dar...
Scalar Perturbation in a Black Hole localized on a Brane
Scalar Perturbation a Black Hole on a Brane
2010/10/18
In this work we study a scalar perturbation in a brane black hole with Schwarzschild behavior, localized on the brane. This black hole solution was derived by Casadio, Fabbri and Mazzacurati with the ...
Scalar Source in Circular Motion Interacting with Massive Klein-Gordon Field in Minkowski Spacetime
Scalar Source Circular Motion Massive Klein-Gordon Field Minkowski Spacetime
2010/10/18
We analyze the scalar radiation emitted by a source in uniform circular motion in Minkowski spacetime interacting with a massive Klein-Gordon field. We assume the source rotating around a central obje...
