Modelling the Decoherence of Spacetime (abridged)
John T. Whelan
Abstract
The question of whether unobserved short-wavelength modes of the gravitational field can induce decoherence in the long-wavelength modes (``the decoherence of spacetime'') is addressed using a scalar field toy model with some features of perturbative general relativity. This is an abridged version of the author's paper gr-qc/9612028.
