Medved, A. J. M. A commentary on Ruppeiner metrics for black holes. (English) Zbl 1149.83320 Mod. Phys. Lett. A 23, No. 26, 2149-2161 (2008). Summary: There has been some recent controversy regarding the Ruppeiner metrics that are induced by Reissner-Nordström (and Reissner-Nordström-like) black holes. Most infamously, why does this family of metrics turn out to be flat, how is this outcome to be physically understood, and can/should the formalism be suitably modified to induce curvature? In this paper, we provide a novel interpretation of this debate. For the sake of maximal analytic clarity and tractability, some supporting calculations are carried out for the relatively simple model of a rotating BTZ black hole.
