Kink solutions in nonlocal scalar field theory models
I. Andrade, R. Menezes, A. Yu. Petrov +1
In this paper, we study in detail various solutions, especially kink ones, in different nonlocal scalar field theories, whose kinetic term is described by an arbitrary non-polynomi…

New brane-like solutions in modified four-dimensional Einstein-Gauss-Bonnet gravity
D. Bazeia, R. Menezes, A. Yu. Petrov +1
We investigate solutions of a new Einstein-Gauss-Bonnet gravity ( ). We first describe the bulk vacuum solution, then we add a massive probe scalar field, and we foll…

Braneworlds in bumblebee gravity
M. A. Marques, R. Menezes, A. Yu. Petrov +1
We investigate thick-brane solutions within the five-dimensional bumblebee gravity in the presence of a real scalar field. Specifically, we implement the Lorentz symmetry breaking…
