Aspects of regular and singular electromagnetic-generalized-quasitopological-gravities black holes in (2+1) dimensions
Jeferson de Oliveira, R. D. B. Fontana, A. B. Pavan
We investigate quasitopological black holes in dimensions in the context of electromagnetic-generalized-quasitopological-gravities (EM-GQT). For three different families of…
Gauss-Bonnet black holes in (2+1) dimensions: Perturbative aspects and entropy features
B. Cuadros-Melgar, R. D. B. Fontana, Jeferson de Oliveira
We investigate some aspects of the -dimensional Gauss-Bonnet black hole proposed in [1][2]. The perturbations of scalar and massless spinorial fields are studied suggesting…
Superradiance and instabilities in black holes surrounded by anisotropic fluids
B. Cuadros-Melgar, R. D. B. Fontana, Jeferson de Oliveira
In this paper we analyze the propagation of a charged scalar field in a Reissner-Nordström black hole endowed with one anisotropic fluid that can play the role of a cosmological te…
Holographic phase transition and Quasinormal modes in Lovelock gravity
Kai Lin, Jeferson de Oliveira, Elcio Abdalla
In this work we aim at discussing the effects of higher order corrections to curvature on the Lovelock AdS black holes quasinormal spectrum and, in the context of gauge/gravity cor…
Holographic Phase Transitions in (2+1)-dimensional black hole spacetimes in NMG
E. Abdalla, Jeferson de Oliveira, A. B. Pavan +1
In this work we aim at the question of holographic phase transitions in two dimensional systems with Lifshitz scaling. We consider the gravity side candidate for a dual description…
Quasinormal modes and thermodynamical aspects of the 3D Lifshitz black hole
B. Cuadros-Melgar, Jeferson de Oliveira, C. E. Pellicer
We consider scalar and spinorial perturbations on a background described by a three-dimensional Lifshitz black hole. We obtained the corresponding quasinormal modes which per…
Scalar field propagation in higher dimensional black holes at a Lifshitz point
Elcio Abdalla, Owen Pavel Fernández Piedra, Fidel Sosa Nuñez +1
We study the complete time evolution of scalar fields propagating in space-times of higher dimensional Lifshitz Black Holes with dynamical critical exponent , obtained from a…
Stability Analysis and Area Spectrum of 3-Dimensional Lifshitz Black Holes
Bertha Cuadros-Melgar, Jeferson de Oliveira, C. E. Pellicer
In this work, we probe the stability of a three-dimensional Lifshitz black hole by using scalar and spinorial perturbations. We found an analytical expression for the quasino…
Three dimensional Lifshitz black hole and the Korteweg-de Vries equation
E. Abdalla, Jeferson de Oliveira, A. Lima Santos +1
We consider a solution of three dimensional New Massive Gravity with a negative cosmological constant and use the AdS/CTF correspondence to inquire about the equivalent two dimensi…
Fermion perturbations in string-theory black holes
Owen Pavel Fernández Piedra, Jeferson de Oliveira
In this paper we study fermion perturbations in four dimensional black holes of string theory, obtained either from a non-extreme configuration of three intersecting five-branes wi…
