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 methods…
Polymer Black Hole Surrounded by Quintessence
M. C. Araújo, J. G. Lima, C. R. Muniz +1
In this paper, we study the polymer black hole solution surrounded by a quintessence field. The influence of quintessence on the polymer black hole is investigated through its ther…
LQG inspired spacetimes as solutions of the Einstein equations
Marcos V. de S. Silva, Carlos F. S. Pereira, G. Alencar +1
Black bounces are compact objects with a wormhole structure hidden behind an event horizon. This type of metric can be obtained through general relativity by considering the presen…
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…
Black holes inside cosmic voids
Francisco Bento Lustosa, Milko Estrada, Marcony S. Cunha +1
This study examines the gravitational and thermodynamic properties of static, spherically symmetric black holes within cosmic voids -- vast underdense regions of the universe. By d…
Static and stationary loop quantum black bounces
C. R. Muniz, G. Alencar, M. S. Cunha +1
We explore a static and stationary black bounce geometry inspired by Loop Quantum Gravity (LQG), focusing on how LQG corrections and regularization parameters affect its properties…
Generating 4-dimensional Wormholes with Yang-Mills Casimir Sources
A. C. L. Santos, R. V. Maluf, C. R. Muniz
This work presents a new wormhole solution in General Relativity supported by the quantum vacuum fluctuations of the Casimir effect between perfect chromometallic mirrors in $(3+1)…
Regular Black Holes in with Gravity
A. C. L. Santos, R. V. Maluf, C. R. Muniz
Despite the experimental success of general relativity in the scales it has been tested, there are still some inconsistencies, such as explaining the acceleration of the universe a…
Dymnikova GUP-corrected black holes
G. Alencar, Milko Estrada, C. R. Muniz +1
We consider the impact of Generalized Uncertainty Principle (GUP) effects on the Dymnikova regular black hole. The minimum length scale introduced by the GUP modifies the energy de…
Yang-Mills Casimir wormholes in
Alana C. L. Santos, Célio R. Muniz, Roberto V. Maluf
This work presents new three-dimensional traversable wormhole solutions sourced by the Casimir density and pressures related to the quantum vacuum fluctuations in Yang-Mills (Y-M)…
Dymnikova-Schwinger traversable wormholes
Milko Estrada, Celio R. Muniz
In this paper, we obtain new -dimensional and asymptotically flat wormhole solutions by assuming a specific form of the energy density distribution. This is addressed by conside…
