This work deals with thick braneworld models, in an environment where the Ricci scalar is changed to accommodate the addition of two extra terms, one depending on the Ricci scalar …

In this paper the kink scattering in a two-component scalar field theory model in (1+ 1)- Minkowskian space-time is addressed. The potential term U (ϕ 1, ϕ 2) is given by a …
A family of deformed models of the sine–Gordon-type can be generated by twisting the sine– Gordon model. As a particular case, the 3-sine–Gordon model is here addressed, whose …
We show that a possible resolution to the stabilization of an extra spatial dimension (radion) can be obtained solely in the context of gravitational dynamics itself without the necessity of …
Warped braneworld models have the potential to provide a plausible resolution to the gauge hierarchy problem but at the cost of introduction of an additional field, namely the interbrane …
In this work we start from the Higgs prototype model to introduce a new model, which makes a smooth transition between systems with well-located minima and systems that support no …
This work discusses the construction of braneworld solutions in modified gravity with Lagrange multipliers. We examine the general aspects of the model and present a first-order …

We discuss possible instabilities in higher-derivative matter field theories. These theories have two free parameters β _1 β 1 and β _4 β 4. By using a dynamical system approach we …
Esta tese lida com estruturas localizadas em Teoria de Campos no espaço plano e curvo. Inicialmente, investigamos a presença de soluções tipo kink em (1, 1) dimensões em …
