Virtual work, thermodynamic structure of the spacetime, and black hole criticality
Dumitru Astefanesei, Gonzalo Casanova, Raul Rojas
We propose a new way to relate the black hole thermodynamics and geometry by generalizing the Euclidean formalism to include "virtual geometries", which do not necessarily satisfy…

On the existence of thermodynamically stable asymptotically flat black holes
Dumitru Astefanesei, Romina Ballesteros, Paulina Cabrera +2
We use the quasilocal formalism of Brown and York, supplemented with counterterms, to investigate the thermodynamics of asymptotically flat black holes. We consider two families of…
