p-brane dynamics in N+1-dimensional FRW universes
P. P. Avelino, R. Menezes, L. Sousa
We study the evolution of maximally symmetric -branes with a $S_{p-i}\otimes \mathbbm{R}^i$ topology in flat expanding or collapsing homogeneous and isotropic universes with $N+…
Dynamics of domain wall networks with junctions
P. P. Avelino, C. J. A. P. Martins, J. Menezes +2
We use a combination of analytic tools and an extensive set of the largest and most accurate three-dimensional field theory numerical simulations to study the dynamics of domain wa…
Dynamics of Biased Domain Walls and the Devaluation Mechanism
P. P. Avelino, C. J. A. P. Martins, L. Sousa
We study the evolution of biased domain walls in the early universe. We explicitly discuss the roles played by the surface tension and volume pressure in the evolution of the walls…
On the cosmological evolution of alpha and mu and the dynamics of dark energy
P. P. Avelino
We study the cosmological evolution of the fine structure constant, , and the proton-to-electron mass ratio, , in the context of a generic class of models where the g…
Clustering Properties of Dynamical Dark Energy Models
P. P. Avelino, L. M. G. Beca, C. J. A. P. Martins
We provide a generic but physically clear discussion of the clustering properties of dark energy models. We explicitly show that in quintessence-type models the dark energy fluctua…
