Semiclassical Quantum Gravity: Statistics of Combinatorial Riemannian Geometries
Luca Bombelli, Alejandro Corichi, Oliver Winkler
This paper is a contribution to the development of a framework, to be used in the context of semiclassical canonical quantum gravity, in which to frame questions about the correspo…
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…
The moduli space of isometry classes of globally hyperbolic spacetimes
Luca Bombelli, Johan Noldus
This is the last article in a series of three initiated by the second author. We elaborate on the concepts and theorems constructed in the previous articles. In particular, we prov…
