A Covariant Polymerized Scalar Field in Semi-Classical Loop Quantum Gravity
Rodolfo Gambini, Florencia Benítez, Jorge Pullin
Abstract
We propose a new polymerization scheme for scalar fields coupled to gravity. It has the advantage of being a (non-bijective) canonical transformation of the fields, and therefore ensures the covariance of the theory. We study it in detail in spherically symmetric situations and compare to other approaches.
