Analytical solutions for Maxwell-scalar system on radially symmetric spacetimes
I. Andrade, D. Bazeia, M. A. Marques +2
We investigate Maxwell-scalar models on radially symmetric spacetimes in which the gauge and scalar fields are coupled via the electric permittivity. We find the conditions that al…
Impurity-doped stable domain walls in spherically symmetric spacetimes
D. Bazeia, M. A. Liao, M. A. Marques
In this work, radially symmetric kink-like solutions in the presence of impurities are investigated for both flat and curved spacetimes, with geometry generated by a rotation…
Scalar-tensor representation to brane with Gauss-Bonnet gravity
A. S. Lobão, João Luís Rosa, D. Bazeia
In this paper, we generalize the analysis of the brane via the inclusion of a term proportional to the Gauss-Bonnet invariant. We consider an action of the form $F(R,G,T)=…
Multi-kink braneworld configurations in the scalar-tensor representation of gravity
D. Bazeia, A. S. Lobão, João Luís Rosa
In this work we investigate the brane in the scalar-tensor representation, where the solutions of the equations of motions for the source field engender topological defect…
Impact of compactlike and asymmetric configurations of thick branes on the scalar-tensor representation of gravity
João Luís Rosa, A. S. Lobão, D. Bazeia
In this work we study braneworld models in generalized gravity theories where the action depends on a function of the Ricci scalar and the trace of the stre…

In this work we study braneworld configurations in the scalar-tensor representation of the gravity theory in the presence of a Cuscuton term in the source field…
Thick branes in the scalar-tensor representation of gravity
João Luís Rosa, Matheus A. Marques, Dionisio Bazeia +1
Braneworld scenarios consider our observable universe as a brane embedded in a five-dimensional bulk. In this work, we consider thick braneworld systems in the recently proposed dy…
Novel modified gravity braneworld configurations with a Lagrange multiplier
Dionisio Bazeia, Douglas A. Ferreira, Francisco S. N. Lobo +1
In this work we deal with thick brane solutions in the warped five-dimensional braneworld scenario with a single extra spatial dimension of infinite extent, for a class of modified…
Thick brane structures in generalized hybrid metric-Palatini gravity
João Luís Rosa, Douglas A. Ferreira, Dionisio Bazeia +1
In this work, we study 5-dimensional braneworld scenarios in the scalar-tensor representation of the generalized hybrid metric-Palatini gravitational theory. We start by considerin…
Black holes in realistic branes: black string-like objects?
D. Bazeia, J. M. Hoff da SIlva, Roldao da Rocha
A realistic model describing a black string-like object in an expanding Universe is analyzed in the context of the McVittie's solution of the Einstein field equations. The bulk met…
Gravitacional field of a global defect
D. Bazeia, C. Furtado, A. R. Gomes
Global topological defects described by real scalar field in (3,1) dimensions coupled to gravity are analyzed. We consider a class of scalar potentials with explicit dependence wit…
