Generalized Thermodynamics and Phase Transitions of Vaidya-adS Black Holes
A. F. Cardona, C. Molina
This work investigates the thermodynamics of non-stationary anti-de Sitter (adS) black holes and their gauge-gravity duals. To model a non-equilibrium process, we employ a time-dep…
Hawking atmosphere of anti-de Sitter black holes
A. F. Cardona, C. Molina
This work investigates the semiclassical evolution of the Hawking atmosphere surrounding evaporating, spherically symmetric anti-de Sitter (adS) black holes. We model the evaporati…
Black-Hole Thermodynamics from Gauge Freedom in Extended Iyer-Wald Formalism
Thiago de L. Campos, Mario C. Baldiotti, C. Molina
Thermodynamic systems admit multiple equivalent descriptions related by transformations that preserve their fundamental structure. This work focuses on exact isohomogeneous transfo…
Dynamical black holes and accretion-induced backreaction
Thiago de L. Campos, C. Molina, Mario C. Baldiotti
We investigate the evolution of future trapping horizons through the dynamics of the Misner-Sharp mass using ingoing Eddington-Finkelstein coordinates. Our analysis shows that an i…
Geodesic dynamics in brane-de Sitter wormholes
W. S. Klën, R. C. Barboza, C. Molina
We present a dynamical analysis of the null and timelike geodesics around an asymptotically de Sitter wormhole in a Randall-Sundrum brane. In this framework, the wormhole throat is…
Stability of the spacetime of a magnetized compact object
Eveling C. Ribeiro, L. Formigari, Marcos R. Ribeiro +5
We investigate the stability of scalar perturbations around a magnetized stationary compact object in General Relativity. The considered object is one of the simplest exact solutio…
Black-hole evaporation for cosmological observers
Thiago de L. Campos, C. Molina, J. A. S. Lima
This work investigates the evaporation of black holes immersed in a de Sitter environment, using the Vaidya-de Sitter spacetime. The role of cosmological observers is highlighted i…
Generating Kerr-anti-de Sitter thermodynamics
T. L. Campos, M. C. Baldiotti, C. Molina
In the present work we study the construction of different thermodynamic descriptions for the Kerr-anti-de Sitter (KadS) black holes. The early versions of the KadS thermodynamics…
Weyl conjecture and thermal radiation of finite systems
M. C. Baldiotti, M. A. Jaraba, L. F. Santos +1
In this work, corrections for the Weyl law and Weyl conjecture in d dimensions are obtained and effects related to the polarization and area term are analyzed. The derived formalis…
