Geometrothermodynamics of Black Hole Shadows: A Review

Hernando Quevedo, Jose M. Ladino, Carlos E. Romero-Figueroa +1

Black-hole shadows and geometrothermodynamics (GTD) are defined in different spaces but depend on the same macroscopic black-hole parameters. We review their correspondence for Rei…

Naked Singularities and Black Hole Thermodynamics from Shadows and Photon Rings in the Quantum Oppenheimer-Snyder Model

Jose Miguel Ladino, Anuar Idrissov, Carlos E. Romero-Figueroa +1

We investigate the optical and thermodynamic properties of quantum Oppenheimer-Snyder (qOS) spacetimes in both the black hole and naked singularity regimes. By analyzing test-parti…

Geometric Universality and Thermodynamic Microstructure of Real Fluids in a Unified Entropic Framework

Carlos E. Romero-Figueroa, Jose Miguel Ladino, Sasha A. Zaldivar +1

We introduce a unified entropic framework for real fluids that encompasses the van der Waals, Berthelot, Redlich Kwong, and Peng Robinson equations of state within a common thermod…

Phase Transitions, Shadows, and Microstructure of Kerr-anti-de Sitter Black Holes from Geometrothermodynamics

Jose Miguel Ladino, Carlos E. Romero-Figueroa, Hernando Quevedo

Using the formalism of geometrothermodynamics, we investigate the phase-transition structure and microstructure of the Kerr-anti-de Sitter black hole and show the relationship with…

Phase transitions, shadows, and microstructure of Reissner-Nordström-Anti-de-Sitter black holes from a geometrothermodynamic perspective

Jose M. Ladino, Carlos E. Romero-Figueroa, Hernando Quevedo

We study the thermodynamic properties of the Reissner-Nordström black hole with cosmological constant, expressed in terms of the curvature radius, by using the approach of shadow t…

Comparing spin supplementary conditions for particle motion around traversable wormholes

Carlos A. Benavides-Gallego, Jose Miguel Ladino, Eduard Larrañaga

The Mathisson-Papapetrou-Dixon (MPD) equations describe the motion of spinning test particles. It is well-known that these equations, which couple the Riemann curvature tensor with…

Motion of Spinning Particles around Black Holes

Jose Miguel Ladino, Carlos Andrés del Valle, Eduard Larrañaga

The motion of spinning particles around compact objects, for example a rotating stellar object moving around a supermassive black hole, is described by differential equations that…

Implementación computacional para el estudio de partículas con espín en agujeros negros rotantes modificados cuánticamente

Jose Miguel Ladino, Eduard Larrañaga

The trajectories of test particles with spin orbiting a black hole depend on the geometry of space-time and the intrinsic physical characteristics of the test particles. In this wo…
