Searching for classical geometries in spin foam amplitudes: a numerical method
Pietro Dona, Francesco Gozzini, Giorgio Sarno
We develop a numerical method to investigate the semiclassical limit of spin foam amplitudes with many vertices. We test it using the Ponzano-Regge model, a spin foam model for thr…

Typical entanglement entropy in the presence of a center: Page curve and its variance
Eugenio Bianchi, Pietro Dona
In a quantum system in a pure state, a subsystem generally has a nonzero entropy because of entanglement with the rest of the system. Is the average entanglement entropy of pure st…

Numerical study of the Lorentzian Engle-Pereira-Rovelli-Livine spin foam amplitude
Pietro Dona, Marco Fanizza, Giorgio Sarno +1
The Lorentzian EPRL spin foam amplitude for loop quantum gravity is a multi-dimensional non-compact integral of highly oscillating functions. Using a method based on the decomposit…
