Palatini wormholes and energy conditions from the prism of general relativity
(Springer, 2017-11)
Wormholes are hypothetical shortcuts in spacetime that in general relativity unavoidably violate all of the pointwise energy conditions. In this paper, we consider several wormhole spacetimes that, as opposed to the standard ...
Thin-shell wormholes with charge in F(R) gravity
(Springer, 2016-03)
In this article, we construct a class of constant curvature and spherically symmetric thin-shell Lorentzian wormholes in F(R) theories of gravity and we analyze their stability under perturbations preserving the symmetry. ...
New scalar compact objects in Ricci-based gravity theories

Einstein-Maxwell-dilaton theory: Black holes, wormholes, and applications to AdS/CMT
(Universidade Estadual Paulista (Unesp), 2017-11-21)
No contexto de teorias de Einstein-Maxwell-dilaton, estudamos buracos negros, buracos de minhoca e aplicações à correspondência anti-de Sitter/Teoria de Matéria Condensada. Apresentamos a solução de buracos negro dyonica ...
Black holes and wormholes in AdS branes
(AMER PHYSICAL SOC, 2010)
In this work we have derived a class of geometries which describe black holes and wormholes in Randall-Sundrum-type brane models, focusing mainly on asymptotically anti-de Sitter backgrounds. We show that by continuously ...
Fully resonant scalars on asymptotically AdS wormholes.
In this work, we show the existence of asymptotically anti-de Sitter (AdS) wormhole geometries in which the scalar probe has an equispaced, fully resonant spectrum, as that of a scalar on AdS spacetime, and explore its ...

Scalar-tensor teleparallel wormholes by Noether symmetries
(2016)
A gravitational theory of a scalar field nonminimally coupled with torsion and a boundary term is considered with the aim to construct Lorentzian wormholes. Geometrical parameters including shape and redshift functions are ...
