Abstract: We consider the quantization of the midi-superspace associated with a class of spacetimes with toroidal isometrics, but without the compact spatial hypersurfaces of the well-known Gowdy models.By a symmetry reduction, the phase space for the system at the classical level can be identified with that of a free massless scalar field on a fixed background spacetime, thereby providing a simple route to quantization.We are then able to study certain non-perturbative features of the quantum gravitational system.In particular, we examine the quantum geometry of the asymptotic regions of the spacetimes involved and find some surprisingly large dispersive effects of quantum gravity.
