Non-extensive and quasi-homogeneous geometrothermodynamics
Hernando Quevedo, MarÃa N. Quevedo
We study the thermodynamic properties of black holes, taking into account the non-extensive character of their entropy at the thermodynamic and statistical level. To this end, we a…

Geometrothermodynamics and critical behavior of regular black holes
H. Quevedo, M. N. Quevedo, A. Sanchez
We apply the formalism of quasi-homogeneous geometrothermodynamics to study the stability, phase transition, and criticality properties of the Bardeen regular black hole. We show t…

Geometrothermodynamic description of magnetic materials
Hernando Quevedo, Maria N. Quevedo, Alberto Sanchez
We perform a statistical and geometrothermodynamic analysis of three different models of magnetic materials, namely, the translational free model, the spin model, and the mean-fiel…
