Fermionic field perturbations of a three-dimensional Lifshitz black hole in conformal gravity
P. A. González, Yerko Vásquez, Ruth Noemi Villalobos
We study the propagation of massless fermionic fields in the background of a three-dimensional Lifshitz black hole, which is a solution of conformal gravity. The black hole solutio…
Four-dimensional black holes with scalar hair in nonlinear electrodynamics
José O. Barrientos, P. A. González, Yerko Vásquez
We consider a gravitating system consisting of a scalar field minimally coupled to gravity with a self-interacting potential and a U(1) nonlinear electromagnetic field. Solving ana…
Evanescent gravitons in Warped Anti-de Sitter space
Gaston Giribet, Yerko Vasquez
Besides black holes, the phase space of three-dimensional massive gravity about Warped-Anti de Sitter (WAdS) space contains solutions that decay exponentially in time. They describ…
Quasinormal modes of non-Abelian hyperscaling violating Lifshitz black holes
Ramón Bécar, P. A. González, Yerko Vásquez
We study the quasinormal modes of scalar field perturbations in the background of non-Abelian hyperscaling violating Lifshitz black holes. We find that the quasinormal frequencies…
Scalar Perturbations of Nonlinear Charged Lifshitz Black Branes with Hyperscaling Violation
P. A. González, Yerko Vásquez
We study scalar perturbations of nonlinear charged Lifshitz black branes with hyperscaling violating factor, and we find numerically the quasinormal modes for scalar fields. Then,…
Teleparallel Equivalent of Lovelock Gravity
P. A. Gonzalez, Yerko Vasquez
There is a growing interest in modified gravity theories based on torsion, as these theories exhibit interesting cosmological implications. In this work, inspired by the teleparall…
Scalar field scattering by a Lifshitz black hole under a non-minimal coupling
Samuel Lepe, Javier Lorca, Francisco Pena +1
We study the behavior of a scalar field under a z = 3 Lifshitz black hole background, in a way that is non-minimally coupled to the gravitational field. A general analytical soluti…
