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 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…

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…
