Toller matrices and the Feynman $i ε$ in spinfoams

Eugenio Bianchi, Chaosong Chen, Mauricio Gamonal

We study the analytic properties and three equivalent representations of the Toller matrices $T^{(\pm)}$ which appear in the causal formulation of spinfoam transition amplitudes fo…

Causal spinfoam vertex for 4d Lorentzian quantum gravity

Eugenio Bianchi, Chaosong Chen, Mauricio Gamonal

We introduce a new causal spinfoam vertex for $4$ d Lorentzian quantum gravity. The causal data are encoded in Toller $T$ -matrices, which add to Wigner $D$ -matrices $T^{(+)}+T^{(-)}…
