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…
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…
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…
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…
Traversable Wormholes Sourced by Dark Matter in Loop Quantum Cosmology
Marcos V. de S. Silva, G. Alencar, R. N. Costa Filho +2
In this work, we investigate the existence of wormholes within the framework of Loop Quantum Cosmology, using isotropic dark matter as the source. We analyze three distinct density…
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)…
Probing the Solar System for Dark Matter Using the Sagnac Effect
A. D. S. Souza, C. R. Muniz, R. M. P. Neves +1
This study investigates the potential of the Sagnac Effect for detecting dark matter in the Solar System, particularly within the Sun. Originating from the relative delay and inter…
