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…
Holographic renormalization and the variational problem for mixed boundary conditions via a solution-dependent superpotential-like function
David Choque, Raúl Rojas
We study holographic renormalization and the variational problem in four-dimensional Einstein gravity coupled to a self-interacting scalar field in asymptotically AdS spacetimes wi…
Extended phase space thermodynamics for hairy black holes
Dumitru Astefanesei, Paulina Cabrera, Robert B. Mann +1
We expand our results in \cite{Astefanesei:2019ehu} to investigate a general class of exact hairy black hole solutions in Einstein-Maxwell-dilaton gravity. The dilaton is endowed w…
Holography of AdS Hairy Black Holes and Cardy-Verlinde Formula
Dumitru Astefanesei, David Choque, Jorge Maggiolo +1
We discuss some aspects related to holography of Anti-de Sitter (AdS) dyonic hairy black holes, which break the conformal symetry of the boundary. We use counterterms for the scala…
Reentrant phase transitions in Einstein-Maxwell-scalar black holes
Dumitru Astefanesei, Paulina Cabrera, Robert B. Mann +1
We consider how scalar fields affect the thermodynamic behavior of charged anti-de Sitter (AdS) black holes. We specifically investigate a class of (3+1)-dimensional exact hairy ch…
Thermodynamically stable asymptotically flat hairy black holes with a dilaton potential: the general case
Dumitru Astefanesei, Jose Luis Blázquez-Salcedo, Francisco Gómez +1
We extend the analysis, initiated in arXiv:1901.01269, of the thermodynamic stability of four-dimensional asymptotically flat hairy black holes by considering a general class of ex…
Hairy Black Hole Chemistry
Dumitru Astefanesei, Robert Mann, Raul Rojas
We study the thermodynamics of an exact hairy black hole solution in Anti-deSitter (AdS) spacetime. We use the counterterm method supplemented with boundary terms for the scalar fi…
Thermodynamically stable asymptotically flat hairy black holes with a dilaton potential
Dumitru Astefanesei, David Choque, Francisco Gomez +1
We present a detailed analysis of the thermodynamics of exact asymptotically flat hairy black holes in Einstein-Maxwell-dilaton theory. We compute the regularized action, quasiloca…
Scalar charges and the first law of black hole thermodynamics
Dumitru Astefanesei, Romina Ballesteros, David Choque +1
We present a variational formulation of Einstein-Maxwell-dilaton theory in flat spacetime, when the asymptotic value of the scalar field is not fixed. We obtain the boundary terms…
