Dynamics of FRW Universes Sourced by Non-Linear Electrodynamics
Ricardo Garcia-Salcedo, Tame Gonzalez, Claudia Moreno +1
We apply the dynamical systems tools to study the (linear) dynamics of Friedmann-Robertson-Walker universes that are fuelled by non-linear electrodynamics. We focus, mainly, in two…
Critical comments on the paper "Crossing by a single scalar field on a Dvali-Gabadadze-Porrati brane" by H Zhang and Z-H Zhu [Phys.Rev.D75,023510(2007)]
Israel Quiros, Ricardo Garcia-Salcedo, Claudia Moreno
It is demonstrated that the claim in the paper "Crossing by a single scalar field on a Dvali-Gabadadze-Porrati brane" by H Zhang and Z-H Zhu [Phys.Rev.D75,023510(2007)], abo…
Soliton structures in a molecular chain model with saturation
E. Villagran, J. Socorro, Ricardo Garcia-Salcedo +1
In the present work, we study, by means of a one-dimensional lattice model, the collective excitations corresponding to intra molecular ones of a chain like proteins. It is shown t…
Self accelerating solutions in a DGP brane with a scalar field trapped on it: the dynamical systems perspective
Israel Quiros, Ricardo Garcia-Salcedo, Tonatiuh Matos +1
We apply the dynamical systems tools to study the linear dynamics of a self-interacting scalar field trapped on a DGP brane. The simplest kinds of self-interaction potentials are i…
Singularity-free Bianchi spaces with nonlinear electrodynamics
Ricardo Garcia-Salcedo, Nora Breton
In this paper we present an analysis to determine the existence of singularities in spatially homogeneous anisotropic universes filled with nonlinear electromagnetic radiation. The…
Nonlinear electrodynamics in Bianchi spacetimes
Ricardo Garcia-Salcedo, Nora Breton
We study the effects produced by nonlinear electrodynamics in spacetimes conformal to Bianchi metrics. In the presence of Born-Infeld type fields these models accelerate, expand an…
