Evolution of the fine-structure constant in the non-linear regime
P. P. Avelino, C. J. A. P. Martins, J. Menezes +1
We study the evolution of the fine-structure constant, , induced by non-linear density perturbations in the context of the simplest class of quintessence models with a non-minim…
One-scale Model for Domain Wall Network Evolution
P. P. Avelino, C. J. A. P. Martins, J. C. R. E. Oliveira
We introduce a new phenomenological one-scale model for the evolution of domain wall networks, and test it against high-resolution field theory numerical simulations. We argue that…
Dynamics of perfect fluid Unified Dark Energy models
L. M. G. Beca, P. P. Avelino
In this paper we show that a \emph{one-to-one} correspondence exists between any dark energy model and an equivalent (from a cosmological point of view, in the absence of perturbat…
Understanding Domain Wall Network Evolution
P. P. Avelino, J. C. R. E. Oliveira, C. J. A. P. Martins
We study the cosmological evolution of domain wall networks in two and three spatial dimensions in the radiation and matter eras using a large number of high-resolution field theor…
