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 …
This work deals with thick branes in bulk with a single extra dimension modeled by a two- field configuration. We first consider the inclusion of the cuscuton to also control the …
This work deals with the presence of thick branes in a model with two source scalar fields that interact with one another in a very specific way. The model is new, capable of …

In this paper, we study the thick brane system in the so-called f (Q) gravity, where the gravitational interaction was encoded by the nonmetricity Q like scalar curvature R in …
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 …

In this paper, we investigate thick branes generated by a scalar field in mimetic gravity theory, which is inspired by considering the conformal symmetry under the conformal …
The nature of gravity and its strength compared with other forces are fundamental challenges faced by the actual science. A path to understand the hierarchy problem of …
Nesta tese, discutimos diversas caracterısticas de estruturas tipo-kink tanto no espaço plano quanto no espaço curvo. Inicialmente, revisamos alguns aspectos gerais sobre teorias …
