The generalized first law for more general matter by Hong Zhe Chen

“…Finally, the quantum matter is allowed to contribute nontrivially to asymptotic energy, e.g. as is necessary, even for a minimally coupled Maxwell field, to recover the expected thermodynamic first law of charged black holes.…”

Stability of saddles and choices of contour in the Euclidean path integral for linearized gravity: dependence on the DeWitt parameter by Xiaoyi Liu, Donald Marolf, Jorge E. Santos

“…We study such contours for Euclidean gravity linearized about AdS-Schwarzschild black holes in reflecting cavities with thermal (canonical ensemble) boundary conditions, and we compare path-integral stability of the associated saddles with thermodynamic stability of the classical spacetimes. …”

New non-extremal and BPS hairy black holes in gauged N $$ \mathcal{N} $$ = 2 and N $$ \mathcal{N} $$ = 8 supergravity by Andres Anabalon, Dumitru Astefanesei, Antonio Gallerati, Mario Trigiante

“…We compute the asymptotic charges, thermodynamics and boundary conditions of these black holes and show that all of them, except one, introduce a triple trace deformation in the dual theory.…”

The scope of thermodynamics by Prunkl, C

“…Next I discuss thermodynamics in the context of black holes, and examine the question of whether black hole entropy is genuine thermodynamic entropy, as opposed merely to information-theoretic entropy. …”

Microscopic explanation for black hole phase transitions via Ruppeiner geometry: Two competing factors–the temperature and repulsive interaction among BH molecules by Yong Chen, Haitang Li, Shao-Jun Zhang

“…Charged dilatonic black hole (BH) has rather rich phase diagrams which may contain zeroth-order, first-order as well as reentrant phase transitions (RPTs) depending on the value of the coupling constant α between the electromagnetic field and the dilaton. …”
