f(R)-Brane
V. I. Afonso, D. Bazeia, R. Menezes +1
We investigate the existence of brane solutions in braneworld scenarios described by real scalar field in the presence of modified gravity with a single extra dimension. In…
Constructing networks of defects with scalar fields
V. I. Afonso, D. Bazeia, M. A. Gonzalez Leon +2
We propose a new way to build networks of defects. The idea takes advantage of the deformation procedure recently employed to describe defect structures, which we use to construct…
First-order framework and domain-wall/brane-cosmology correspondence
D. Bazeia, F. A. Brito, F. G. Costa
We address the possibility of finding domain wall solutions from cosmological solutions in brane cosmology. We find first-order equations for corresponding cosmology/domain wall so…
Orbit-based deformation procedure for two-field models
V. I. Afonso, D. Bazeia, M. A. Gonzalez Leon +2
We present a method for generating new deformed solutions starting from systems of two real scalar fields for which defect solutions and orbits are known. The procedure generalizes…
Generalized Global Defect Solutions
D. Bazeia, L. Losano, R. Menezes +1
We investigate the presence of defect structures in generalized models described by real scalar field in space-time dimensions. We work with two distinct generalizations, o…
Perturbative aspects and conformal solutions of F(R) gravity
D. Bazeia, B. Carneiro da Cunha, R. Menezes +1
We investigate perturbative aspects of gravity with a general F(R) Lagrangian, as well as nonperturbative dilatonic solutions. For the first part, we are interested in stability an…
