Dymnikova Black Hole Tidal Forces
M. H. Macêdo, A. A. M. Silva, R. R. Landim
In this work we investigate the tidal properties of the Dymnikova regular black hole and their ef fects on massive particles in radial free-fall. Starting from Dymnikova static, sp…

Topological Thermodynamics of Generalized Bardeen Black Hole
A. A. M. Silva, M. H. Macedo, R. R. Landim
Neves and Saa introduced a two parameter spacetime that includes the Hayward, Bardeen, and Simpson-Visser geometries as particular cases. In this work, we employ the generalized of…

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…
