New variables for 1+1 dimensional gravity
Rodolfo Gambini, Jorge Pullin, Saeed Rastgoo
We show that the canonical formulation of a generic action for 1+1-dimensional models of gravity coupled to matter admits a description in terms of Ashtekar-type variables. This in…

Quantum scalar field in quantum gravity: the vacuum in the spherically symmetric case
Rodolfo Gambini, Jorge Pullin, Saeed Rastgoo
We study gravity coupled to a scalar field in spherical symmetry using loop quantum gravity techniques. Since this model has local degrees of freedom, one has to face ``the problem…
