Numerical methods for spin foam theories
Calculations of spin foam transition amplitudes are very complicated and challenging. In collaboration with CPT Ph.D. students (Giorgio Sarno and Francesco Gozzini), we pioneered numerical calculations in the developing sl2cfoam and sl2cfoam-next (available in this repository). This open-source library evaluates spin foam transition amplitudes using high-performance computing. It is modular (can be used to compute any transition amplitude), scalable (can run on a laptop or a cluster), and user-friendly (a minimal amount of additional code is required, and we provide an interface for the Julia scripting language).
