Flux-area operator and black hole entropy
J. Fernando Barbero G., Jerzy Lewandowski, Eduardo J. S. Villaseñor
We show that, for space-times with inner boundaries, there exists a natural area operator different from the standard one used in loop quantum gravity. This new flux-area operator…
Quantum field theory on a cosmological, quantum space-time
Abhay Ashtekar, Wojciech Kaminski, Jerzy Lewandowski
In loop quantum cosmology, Friedmann-LeMaitre-Robertson-Walker (FLRW) space-times arise as well-defined approximations to specific \emph{quantum} geometries. We initiate the develo…
Physical time and other conceptual issues of QG on the example of LQC
Wojciech Kaminski, Jerzy Lewandowski, Tomasz Pawlowski
Several conceptual aspects of quantum gravity are studied on the example of the homogeneous isotropic LQC model. In particular: The proper time of the co-moving observers is…
