Deformations of the Schwarzschild Black Hole
D. Grumiller
Due to its large number of symmetries the Schwarzschild Black Hole can be described by a specific two-dimensional dilaton gravity model. After reviewing classical, semi-classical a…
How to approach Quantum Gravity - Background independence in 1+1 dimensions
D. Grumiller, W. Kummer
The application of quantum theory to gravity is beset with many technical and conceptual problems. After a short tour d'horizon of recent attempts to master those problems by the i…
Supersymmetric black holes in 2D dilaton supergravity: baldness and extremality
L. Bergamin, D. Grumiller, W. Kummer
We present a systematic discussion of supersymmetric solutions of 2D dilaton supergravity. In particular those solutions which retain at least half of the supersymmetries are groun…
Long time black hole evaporation with bounded Hawking flux
D. Grumiller
The long time behavior of an evaporating Schwarzschild black hole is studied exploiting that it can be described by an effective theory in 2D, a particular dilaton gravity model. A…
Positive specific heat of the quantum corrected dilaton black hole
D. Grumiller, W. Kummer, D. V. Vassilevich
Path integral quantization of dilaton gravity in two dimensions is applied to the CGHS model to the first nontrivial order in matter loops. Our approach is background independent a…
The Classical Solutions of the Dimensionally Reduced Gravitational Chern-Simons Theory
D. Grumiller, W. Kummer
The Kaluza-Klein reduction of the 3d gravitational Chern-Simons term to a 2d theory is equivalent to a Poisson-sigma model with fourdimensional target space and degenerate Poisson…
