Classical limit of quantum gravity in an accelerating universe
Frederic P. Schuller, Mattias N. R. Wohlfarth
A one-parameter deformation of Einstein?Hilbert gravity with an inverse Riemann curvature term is derived as the classical limit of quantum gravity compatible with an accelerating…
Ponzano-Regge model revisited II: Equivalence with Chern-Simons
Laurent Freidel, David Louapre
We provide a mathematical definition of the gauge fixed Ponzano-Regge model showing that it gives a measure on the space of flat connections whose volume is well defined. We then s…
Comparison of QG-Induced Dispersion with Standard Physics Effects
Luca Bombelli, Oliver Winkler
One of the predictions of quantum gravity phenomenology is that, in situations where Planck-scale physics and the notion of a quantum spacetime are relevant, field propagation will…
Semiclassical States in Quantum Cosmology: Bianchi I Coherent States
Brett Bolen, Luca Bombelli, Alejandro Corichi
We study coherent states for Bianchi type I cosmological models, as examples of semiclassical states for time-reparametrization invariant systems. This simple model allows us to st…
