Thick branes in the scalar–tensor representation of f(RT) gravity

JL Rosa, MA Marques, D Bazeia, FSN Lobo - The European Physical …, 2021 - Springer
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 …

Thick brane structures in generalized hybrid metric-Palatini gravity

JL Rosa, DA Ferreira, D Bazeia, FSN Lobo - The European Physical …, 2021 - Springer

representation of the generalized hybrid metric-Palatini gravitational theory. We start by …

Internal structure of cuscuton Bloch brane

D Bazeia, DA Ferreira, MA Marques - The European Physical Journal C, 2021 - Springer
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 …

Symmetric and asymmetric thick brane structures

D Bazeia, DA Ferreira, MA Marques - The European Physical …, 2020 - epjplus.epj.org
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 …

Thick braneworld model in nonmetricity formulation of general relativity and its stability

QM Fu, L Zhao, QY Xie - The European Physical Journal C, 2021 - Springer
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 …

Novel modified gravity braneworld configurations with a Lagrange multiplier

D Bazeia, DA Ferreira, FSN Lobo, JL Rosa - The European Physical …, 2021 - Springer
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 …

First-order formalism and thick branes in mimetic gravity

QY Xie, QM Fu, TT Sui, L Zhao, Y Zhong - Symmetry, 2021 - mdpi.com
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 …
