On the quantum fate of singularities in a dark-energy dominated universe
Mariam Bouhmadi-Lopez, Claus Kiefer, Barbara Sandhoefer +1
Classical models for dark energy can exhibit a variety of singularities, many of which occur for scale factors much bigger than the Planck length. We address here the issue whether…
Nonlocal Gravity Simulates Dark Matter
Friedrich W. Hehl, Bahram Mashhoon
A nonlocal generalization of Einstein's theory of gravitation is constructed within the framework of the translational gauge theory of gravity. In the linear approximation, the non…
Quantum geometrodynamics: whence, whither?
Claus Kiefer
Quantum geometrodynamics is canonical quantum gravity with the three-metric as the configuration variable. Its central equation is the Wheeler--DeWitt equation. Here I give an over…
Measurement Analysis and Quantum Gravity
Mark Albers, Claus Kiefer, Marcel Reginatto
We consider the question of whether consistency arguments based on measurement theory show that the gravitational field must be quantized. Motivated by the argument of Eppley and H…
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…
