We discuss the asymptotic behavior of regulated field commutators for linearly polarized, cylindrically symmetric gravitational waves and the mathematical techniques needed for this analysis. We concentrate our attention on the effects brought about by the introduction of a physical cutoff in the study of the microcausality of the model and describe how the different physically relevant regimes are affected by its presence. Specifically we discuss how genuine quantum gravity effects can be… Expand

3-dimensional gravity coupled to Maxwell (or Klein-Gordon) fields is exactly soluble under the assumption of axi-symmetry, and it is shown that the quantum fluctuations in the geometry are large unless the number and frequency of photons satisfy the inequality. Expand
On the metric operator for quantum cylindrical waves
Every (one-polarization) cylindrical wave solution of vacuum general relativity is completely determined by a corresponding axisymmetric solution to the free scalar wave equation on an auxiliary (2 +Expand
Gauge-invariant Hamiltonian dynamics of cylindrical gravitational waves
The model of cylindrical gravitational waves is employed to work out and check a recent proposal of how a diffeomorphism-invariant Hamiltonian dynamics is to be constructed. The starting point is theExpand

Large quantum gravity effects and nonlocal variables
We reconsider here the model where large quantum gravity effects were first found, but now in its null surface formulation (NSF). We find that although the set of coherent states for Z, the basicExpand

We re-examine the large quantum gravity effects discovered by Ashtekar in the context of (2+1)-dimensional gravity coupled to matter. We study an alternative one-parameter family of coherent statesExpand
Time Uncertainty in Quantum Gravitational Systems
It is generally argued that the combined effect of the Heisenberg principle and general relativity leads to a minimum time uncertainty. Most of the analyses supporting this conclusion are based on aExpand
