Spinfoams and high-performance computing
Numerical methods are a powerful tool for doing calculations in spinfoam theory. We review
the major frameworks available, their definition, and various applications. We start from …

Spin Foams, Refinement Limit, and Renormalization
Spin foams provide path integrals for quantum gravity, which employ discretizations as
regulator. To obtain regulator independent predictions, we must remove these fiducial …
