Mass Spectrum and Statistical Entropy of the BTZ black hole from Canonical Quantum Gravity
Cenalo Vaz, Sashideep Gutti, Claus Kiefer +2
In a recent publication we developed a canonical quantization program describing the gravitational collapse of a spherical dust cloud in 2+1 dimensions with a negative cosmological…
Quantum Gravitational Collapse and Hawking Radiation in 2+1 Dimensions
Cenalo Vaz, Sashideep Gutti, Claus Kiefer +1
We develop the canonical theory of gravitational collapse in 2+1 dimensions with a negative cosmological constant and obtain exact solutions of the Wheeler--DeWitt equation regular…
Gibbs' paradox and black-hole entropy
Claus Kiefer, Gerhard Kolland
In statistical mechanics Gibbs' paradox is avoided if the particles of a gas are assumed to be indistinguishable. The resulting entropy then agrees with the empirically tested ther…
Quantum cosmology with big-brake singularity
Alexander Kamenshchik, Claus Kiefer, Barbara Sandhoefer
We investigate a cosmological model with a big-brake singularity in the future: while the first time derivative of the scale factor goes to zero, its second time derivative tends t…
Hawking radiation from the quantum Lemaitre-Tolman-Bondi model
C. Kiefer, J. Mueller-Hill, T. P. Singh +1
In an earlier paper, we obtained exact solutions of the Wheeler-DeWitt equation for the Lemaitre-Tolman-Bondi (LTB) model of gravitational collapse, employing a lattice regularizat…
The Canonical Approach to Quantum Gravity: General Ideas and Geometrodynamics
Domenico Giulini, Claus Kiefer
We give an introduction to the canonical formalism of Einstein's theory of general relativity. This then serves as the starting point for one approach to quantum gravity called qua…
