Scaling Symmetry in Symplectic Thermodynamics
M. C. Baldiotti, R. Fresneda
This paper investigates scaling symmetry in thermodynamics by unifying constrained Hamiltonian dynamics with symplectic and contact geometries. Through the mathematical processes o…
Canonical quantization for Equilibrium Thermodynamics
Luis F. Santos, Victor Hugo M. Ramos, Danilo Cius +2
We formulate a canonical quantization of Equilibrium Thermodynamics by applying Dirac's theory of constrained systems. Thermodynamic variables are treated as conjugate pairs of coo…
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…
Accretion of Generalized Chaplygin Gas onto Cosmologically Coupled Black Holes
Luis F. Reis, Mario C. Baldiotti, Orfeu Bertolami
We study the accretion of cosmic dark fluids, responsible for driving the accelerated expansion of the universe, onto cosmologically coupled black holes. More specifically, we focu…
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…
