Black hole thermodynamics with the cosmological constant as independent variable: Bridge between the enthalpy and the Euclidean path integral approaches

José P. S. Lemos, Oleg B. Zaslavskii

Viewing the cosmological constant as an independent variable, we consider the thermodynamics of the Schwarzschild black hole in an anti-de Sitter (AdS) background. For this s…

Unified approach to the entropy of an extremal rotating BTZ black hole: Thin shells and horizon limits

José P. S. Lemos, Masato Minamitsuji, Oleg B. Zaslavskii

Using a thin shell, the first law of thermodynamics, and a unified approach, we study the thermodymanics and find the entropy of a (2+1)-dimensional extremal rotating Bañados-Teite…

Thermodynamics of extremal rotating thin shells in an extremal BTZ spacetime and the extremal black hole entropy

José P. S. Lemos, Masato Minamitsuji, Oleg B. Zaslavskii

In a (2+1)-dimensional spacetime with a negative cosmological constant, the thermodynamics and the entropy of an extremal rotating thin shell, i.e., an extremal rotating ring, are…

Entropy of extremal black holes: horizon limits through charged thin shells, a unified approach

José P. S. Lemos, Gonçalo M. Quinta, Oleg B. Zaslavskii

Using a unified approach we study the entropy of extremal black holes through the entropy of an electrically charged thin shell. We encounter three cases in which a shell can be ta…

Entropy of an extremal electrically charged thin shell and the extremal black hole

José P. S. Lemos, Gonçalo M. Quinta, Oleg B. Zaslavskii

There is a debate as to what is the value of the the entropy of extremal black holes. There are approaches that yield zero entropy , while there are others that yield the…

Entropy of a self-gravitating electrically charged thin shell and the black hole limit

José P. S. Lemos, Gonçalo M. Quinta, Oleg B. Zaslavskii

A static self-gravitating electrically charged spherical thin shell embedded in a (3+1)-dimensional spacetime is used to study the thermodynamic and entropic properties of the corr…

Boulware state in exactly solvable models of 2D dilaton gravity

O. B. Zaslavskii

We discuss self-consistent geometries and behavior of dilaton in exactly solvable models of 2D dilaton gravity, with quantum fields in the Boulware state. If the coupling be…

Two-dimensional quantum-corrected black hole in a finite size cavity

O. B. Zaslavskii

We consider the gravitation-dilaton theory (not necessarily exactly solvable), whose potentials represent a generic linear combination of an exponential and linear functions of the…

Exactly solvable models of two-dimensional dilaton cosmology with quantum backreaction

O. B. Zaslavskii

We consider general approach to exactly solvable 2D dilaton cosmology with one-loop backreaction from conformal fields taken into account. It includes as particular cases previous…

Classification of static and homogeneous solutions in exactly solvable models of two-dimensional dilaton gravity

O. B. Zaslavskii

We give the full list of types of static (homogeneous)solutions within a wide family of exactly solvable 2D dilaton gravities with backreaction of conformal fields. It includes pre…

Exactly solvable models in 2D semiclassical dilaton gravity and extremal black holes

O. B. Zaslavskii

Previously known exactly solvable models of 2D semiclassical dilaton gravity admit, in the general case, only non-extreme black holes. It is shown that there exist exceptional dege…

Regular self-consistent geometries with infinite quantum backreaction in 2D dilaton gravity and black hole thermodynamics: unfamiliar features of familiar models

O. B. Zaslavskii

We analyze the rather unusual properties of some exact solutions in 2D dilaton gravity for which infinite quantum stresses on the Killing horizon can be compatible with regularity…

Quantum extreme black holes at finite temperature and exactly solvable models of 2d dilaton gravity

O. B. Zaslavskii

It is argued that in certain 2d dilaton gravity theories there exist self-consistent solutions of field equations with quantum terms which describe extreme black holes at nonzero t…

Comment on ''Understanding the Area Proposal for Extremal Black Hole Entropy''

O. B. Zaslavskii

A. Ghosh and P. Mitra made the proposal how to explain the area law for the entropy of extreme black holes in some model calculations. I argue that their approach implicitly operat…

Exactly solvable models of two-dimensional dilaton gravity and quantum eternal black holes

O. B. Zaslavskii

New approach to exact solvability of dilaton gravity theories is suggested which appeals directly to structure of field equations. It is shown that black holes regular at the horiz…

Two-Dimensional Self-Consistent Quantum-Corrected Geometries with a Constant Dilaton Feld

O. B. Zaslavskii

It is argued that the existence of constant dilaton field solutions is a generic feature of string-inspired dilaton gravity. Such solutins arise in the extreme limit of black hole…
