Operator Spin Foam Models
Benjamin Bahr, Frank Hellmann, Wojciech Kamiński +2
The goal of this paper is to introduce a systematic approach to spin foams. We define operator spin foams, that is foams labelled by group representations and operators, as the mai…

Asymptotics of 4d spin foam models
John W. Barrett, Richard J. Dowdall, Winston J. Fairbairn +3
We study the asymptotic properties of four-simplex amplitudes for various four-dimensional spin foam models. We investigate the semi-classical limit of the Ooguri, Euclidean and Lo…
