Topological Thermodynamics of Black Holes: Revisiting the methods of winding numbers calculation
A. A. M. Silva, G. Alencar, C. R. Muniz +2
In this paper, the equivalence between two methods for computing winding numbers is established: the approach of -mapping topological current and the residue method. The method…
Field Sources for Generalized Ellis-Bronnikov Wormhole
T. M. Crispim, G. Alencar, C. R. Muniz
The so-called generalized Ellis-Bronnikov wormhole is a modification of the standard Ellis-Bronnikov solution, in which a parameter is introduced-recovering the original Elli…
On regular black string spacetimes in nonlinear electrodynamics
G. Alencar, V. H. U. Borralho, T. M. Crispim +1
In this work, we investigate the coupling of General Relativity with Nonlinear Electrodynamics (NED), governed by a general Lagrangian , to address the ax…
Using thermodynamics to learn gravitational wave physics
Caio César Rodrigues Evangelista, NÃckolas de Aguiar Alves
Black holes are some of the most interesting objects in the universe. While they first arise in the complicated behavior of general relativity, the physical laws ruling their behav…
Lower-dimensional Gauss-Bonnet gravity black holes with quintessence
G. Alencar, T. M. Crispim, J. Macedo +1
In this paper, we study the limit of Gauss-Bonnet gravity with quintessential matter, obtaining exact solutions that extend the BTZ metric through higher-curvature terms an…
Traversable wormholes from a smoothed string fluid in 4D Einstein-Gauss-Bonnet gravity
C. R. Muniz, M. S. Cunha, L. C. N. Santos
We investigate traversable wormhole solutions in four-dimensional Einstein-Gauss-Bonnet (EGB) gravity sourced by a smoothed string fluid. Originally proposed to model regular black…
