Numerical methods for EPRL spin foam transition amplitudes and Lorentzian recoupling theory
Pietro Dona, Giorgio Sarno
The intricated combinatorial structure and the non-compactness of the Lorentz group have always made the computation of EPRL spin foam transition amplitudes a ve…

2-vertex Lorentzian Spin Foam Amplitudes for Dipole Transitions
Giorgio Sarno, Simone Speziale, Gabriele V. Stagno
We compute transition amplitudes between two spin networks with dipole graphs, using the Lorentzian EPRL model with up to two (non-simplicial) vertices. We find power-law decreasin…
