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…
