Quantum-statistical constraints on Kerr-anti-de Sitter thermodynamics
T. L. Campos, M. C. Baldiotti, C. Molina
We develop a general framework for interpreting the thermodynamic descriptions of Kerr-anti de Sitter black holes (KadS). These descriptions satisfy a first law and respect the hom…
Quasi-local thermodynamics of Kerr-Newman black holes: Pressure, volume, and shear work
Thiago Campos
While the quasi-local thermodynamics of spherically symmetric black holes is well described by pressure and volume, extending this framework to rotating spacetimes poses a signific…
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…
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…
