Unique factor ordering in the continuum limit of LQC
arXiv:0806.0595 · doi:10.1103/PhysRevD.78.024006
Abstract
We show that the factor ordering ambiguities associated with the loop quantisation of the gravitational part of the cosmological Hamiltonian constraint, disappear at the level of Wheeler-DeWitt equation only for a particular choice of lattice refinement model, which coincides with constraints imposed from phenomenological and consistency arguments.
