Unified geometric description of black hole thermodynamics
J. L. Alvarez, H. Quevedo, A. Sanchez
In the space of thermodynamic equilibrium states we introduce a Legendre invariant metric which contains all the information about the thermodynamics of black holes. The curvature…
Geometrothermodynamics of black holes
Hernando Quevedo
The thermodynamics of black holes is reformulated within the context of the recently developed formalism of geometrothermodynamics. This reformulation is shown to be invariant with…
Entropy and anisotropy
Francisco J. Hernandez, Hernando Quevedo
We address the problem of defining the concept of entropy for anisotropic cosmological models. In particular, we analyze for the Bianchi I and V models the entropy which follows fr…
The field-to-particle transition problem
Jeronimo Cortez, Leonardo Patino, Hernando Quevedo
We formulate in an intuitive manner several conceptual aspects of the field-to-particle transition problem which intends to extract physical properties of elementary particles from…
Reply to the Comment ``On the thermodynamics of inhomogeneous perfect fluid mixtures''
Hernando Quevedo, Ruben D. Zarate
We show that the analysis presented in a recent comment by Coll and Ferrando \cite{comment} (qr-qc/0312058) is based on the erroneous assumption that the chemical potential and fra…
The Big Bang in Gowdy Cosmological Models
Hernando Quevedo
We establish a formal relationship between stationary axisymmetric spacetimes and Gowdy cosmological models which allows us to derive several preliminary results about the ge…
