Generalized BF state in quantum gravity
arXiv:1312.0205 · doi:10.1093/ptep/ptt113
Abstract
The BF state is known as a simple wave function that satisfies three constraints in canonical quantum gravity without a cosmological constant. It is constructed from a product of the group delta functions. Applying the chiral asymmetric extension, the BF state is generalized to the state for real values of the Barbero-Immirzi parameter.
