Spacetime as a Feynman diagram: the connection formulation
Michael P. Reisenberger, Carlo Rovelli
Spin foam models are the path integral counterparts to loop quantized canonical theories. In the last few years several spin foam models of gravity have been proposed, most of whic…

Spin foams as Feynman diagrams
Michael Reisenberger, Carlo Rovelli
It has been recently shown that a certain non-topological spin foam model can be obtained from the Feynman expansion of a field theory over a group. The field theory defines a natu…
