A comprehensive treatment of black hole thermodynamics in two-dimensional dilaton gravity is presented. We derive an improved action for these theories and construct the Euclidean path integral. An essentially unique boundary counterterm renders the improved action finite on-shell, and its variational properties guarantee that the path integral has a well-defined semi-classical limit. We give a detailed discussion of the canonical ensemble described by the Euclidean partition function, and…

Affine quantization of Black Holes: thermodynamics, singularity removal and displaced horizons
In this work we investigate the thermodynamical properties and modified dynamics of black hole solutions in the semiclassical regime of ane coherent state quantization. Using the weak correspondence
On Thermodynamics of 2d Black Holes in Brane Inflationary Potentials
Inspired from the inflation brane world cosmology, we study the thermodynamics of a black hole solution in two dimensional dilaton gravity with an arctangent potential background. We first derive the
Thermodynamics of large AdS black holes
We consider leading order quantum corrections to the geometry of large AdS black holes in a spherical reduction of four-dimensional Einstein gravity with negative cosmological constant. The Hawking
Exact solutions and critical chaos in dilaton gravity with a boundary
A bstractWe consider (1 + 1)-dimensional dilaton gravity with a reflecting dynamical boundary. The boundary cuts off the region of strong coupling and makes our model causally similar to the
Black hole thermodynamics and Hamilton–Jacobi counterterm
We review the construction of the universal Hamilton–Jacobi counterterm for dilaton gravity in two dimensions, derive the corresponding result in the Cartan formulation and elaborate further upon

Semi-classical thermodynamics of quantum extremal surfaces in Jackiw-Teitelboim gravity
Abstract Quantum extremal surfaces (QES), codimension-2 spacelike regions which extremize the generalized entropy of a gravity-matter system, play a key role in the study of the black hole


Boundary counterterms and the thermodynamics of 2-D black holes
We utilize a novel method to study the thermodynamics of two dimensional type 0A black holes with constant RR flux. Our approach is based on the Hamilton-Jacobi method of deriving boundary
Observables for two-dimensional black holes.
This work considers the most general dilaton gravity theory in 1+1 dimensions and finds a simple expression that relates the energy of a generic solution to the magnitude of the corresponding Killing vector, which leads directly to an expression for the entropy.
The first law of thermodynamics for Kerr–anti-de Sitter black holes
We obtain expressions for the mass and angular momenta of rotating black holes in anti-de Sitter backgrounds in four, five and higher dimensions. We verify explicitly that our expressions satisfy the
Evanescent black holes.
A renormalizable theory of quantum gravity coupled to a dilaton and conformal matter in two spacetime dimensions is analyzed and suggests that the collapsing matter radiates away all of its energy before an event horizon has a chance to form, and black holes disappear from the quantum-mechanical spectrum.

It is shown that the canonical ensemble with elements of radius r and temperature T(r) for hot gravity with black holes is well defined and the direct nucleation of black holes from hot flat space can be given a thermodynamically consistent description.
String Propagation in a Black Hole Geometry
An action for the exact string black hole
A local action is constructed describing the exact string black hole discovered by Dijkgraaf, Verlinde and Verlinde in 1992. It turns out to be a special 2D Maxwell-dilaton gravity theory, linear in

Black hole mass and Hamilton-Jacobi counterterms
We apply the method of holographic renormalization to computing black hole masses in asymptotically anti-de Sitter spaces. In particular, we demonstrate that the Hamilton-Jacobi approach to obtaining
Thermodynamics of black holes in anti-de Sitter space
The Einstein equations with a negative cosmological constant admit black hole solutions which are asymptotic to anti-de Sitter space. Like black holes in asymptotically flat space, these solutions
