Numerical calculation of an EPRL spin foam amplitude
SUMMER2022
Lecture at the LOOPS22 Summer School - None
In this lecture (about two hours), we showcase the basic usage of the sl2cfoam-next library. We briefly discuss the reformulation of the EPRL transition amplitude in terms of booster functions at the base of the numerical library. We provide two explicit examples of amplitude calculations involving one and four vertices. We discuss in detail the necessary approximations and how to control them.
