Phase transitions in geometrothermodynamics
H. Quevedo, A. Sanchez, S. Taj +1
Using the formalism of geometrothermodynamics, we investigate the geometric properties of the equilibrium manifold for diverse thermodynamic systems. Starting from Legendre invaria…
Geometric description of BTZ black holes thermodynamics
Hernando Quevedo, Alberto Sanchez
We study the properties of the space of thermodynamic equilibrium states of the Bañados-Teitelboim-Zanelli (BTZ) black hole in (2+1)-gravity. We use the formalism of geometrothermo…
Gowdy Cosmological Models in N=1 Supergravity
Alfredo Macias, Hernando Quevedo, Alberto Sanchez
We investigate the canonical quantization of supergravity N=1 in the case of a midisuperspace described by Gowdy cosmological models. The quantum constraints are analyzed and…
Generating Gowdy cosmological models
A. Sanchez, A. Macias, H. Quevedo
Using the analogy with stationary axisymmetric solutions, we present a method to generate new analytic cosmological solutions of Einstein's equation belonging to the class of …
