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…
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…
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…
New Constraints on Varying Alpha
C. J. A. P. Martins
I briefly present some current theoretical motivations for time or space variations of the fundamental constants of nature and review current key observational results. I focus on…
