Title |
Implementation of Conformal Scaling in Loop Quantum Gravity via the Barbero-Immirzi Parameter | |||||

Abstract |
Various arguments over the years have called for implementing conformal scaling into theories of gravity. Standard loop quantum gravity does not take into account this concept. There does exist in the theory a free parameter which sets length scales, the Barbero-Immirzi parameter. Presented here is an analysis of the conformal scaling of the triad formalism and the revelation that the Barbero-Immirzi parameter precisely corresponds to the conformal scale factor. Furthermore, at the kinematical level the conformal scale factor materializes as a scalar field coupled to gravity. The development of this conformal theory to the quantum sector of the theory is also sketched. |
