Spectral Triples of Holonomy Loops
In my talk I will present how a spectral triple is constructed by rearranging central elements of canonical quantum gravity. I will show that the construction quantizes the Poisson structure of General Relativity when formulated in Ashtekar variables. Finally, it turns out that the Dirac Hamiltonian emerges naturally from the spectral triple construction in a semi-classical limit, indicating that the construction involves also matter degrees of freedom.
