Spin foams, Refinement limit and Renormalization
Seth K. Asante, Bianca Dittrich, Sebastian Steinhaus
Spin foams provide path integrals for quantum gravity, which employ discretizations as regulator. To obtain regulator independent predictions, we must remove these fiducial structu…
Spin-foams as semi-classical vertices: gluing constraints and a hybrid algorithm
Seth K. Asante, José Diogo Simão, Sebastian Steinhaus
Numerical methods in spin-foam models have significantly advanced in the last few years, yet challenges remain in efficiently extracting results for amplitudes with many quantum de…
Toward matter dynamics in spin foam quantum gravity
Masooma Ali, Sebastian Steinhaus
Any approach to pure quantum gravity must eventually face the question of coupling quantum matter to the theory. In the past, several ways of coupling matter to spin foam quantum g…
Numerical evaluation of spin foam amplitudes beyond simplices
Courtney Allen, Florian Girelli, Sebastian Steinhaus
We present the first numerical calculation of the 4D Euclidean spin foam vertex amplitude for vertices with hypercubic combinatorics. Concretely, we compute the amplitude for coher…
