Scaling of cosmological domain wall networks with junctions
P. P. Avelino, C. J. A. P. Martins, J. Menezes +2
We describe the results of the largest and most accurate three-dimensional field theory simulations of domain wall networks with junctions. We consider a previously introduced clas…
Frustrated Expectations: Defect Networks and Dark Energy
P. P. Avelino, C. J. A. P. Martins, J. Menezes +2
We discuss necessary conditions for a network of cosmic domain walls to have a chance of providing the dark energy that might explain the recent acceleration of the universe. We de…
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…
Cosmic strings in Bekenstein-type models
J. Menezes, P. P. Avelino, C. Santos
We study static cosmic string solutions in the context of Bekenstein-type models. We show that there is a class of models of this type for which the classical Nielsen-Olesen vortex…
