This work deals with defect structures in models described by scalar fields. The
investigations focus on generalized models, with the kinetic term modified to allow for a …

In this work we study braneworld configurations in the scalar–tensor representation of
the\(f\left (R, T\right)\) gravity theory in the presence of a Cuscuton term in the source field …

Among the multiple 5D thick braneworld models that have been proposed in the last years,
in order to address several open problems in modern physics, there is a specific one …

A bstract We study evolution and thermodynamics of a slow-roll transition between early and
late time de Sitter phases, both in the homogeneous case and in the presence of a black …

A bstract In many nonlinear field theories, relevant solutions may be found by reducing the
order of the original Euler-Lagrange equations, eg, to first order equations (Bogomolnyi …

This work deals with braneworld scenarios with generalized teleparallel gravity. We extend
a recent investigation, where the model studied was described by F (T)= T+ k T n. In the …

The localization of gravity for (5+ 1)-dimensional intersecting thick braneworld models is
thoroughly investigated. Departing from preliminary results for five independent proposals …

Two codimensional thick braneworlds are investigated in quite general terms for two
intersecting scalar fields generating the extra dimension defect. In general, when one …

We investigate braneworld models in the presence of the several scalar fields with
generalized dynamics. A new mechanism to control the internal structure of brane in …

This work deals with the presence of defect structures in generalized sine-Gordon models.
The models are described by periodic potentials, with substructure having one, two, three, or …
