Geometrothermodynamics of black holes in two dimensions
arXiv:0902.4488 · doi:10.1103/PhysRevD.79.087504
Abstract
We study the properties of two-dimensional dilatonic black holes from the viewpoint of geometrothermodynamics. We show that the thermodynamic curvature of the equilibrium space vanishes only in the case of a flat spacetime, and it reproduces correctly the behavior of the thermodynamic interaction and phase transition structure of the corresponding black hole configurations.
