Efficient Tensor Network Algorithms for Spin Foam Models
Seth K. Asante, Sebastian Steinhaus
Numerical computations and methods have become increasingly crucial in the study of spin foam models across various regimes. This paper adds to this field by introducing new algori…
A Monte Carlo algorithm for spin foam intertwiners
Sebastian Steinhaus
Monte Carlo algorithms are barely considered in spin foam quantum gravity. Due to the quantum nature of spin foam amplitudes one cannot readily apply them, and the present sign pro…
Curvature effects in the spectral dimension of spin foams
Alexander Jercher, Sebastian Steinhaus, Johannes Thürigen
It has been shown in [1] that a class of restricted spin foam models can feature a reduced spectral dimension of space-time. However, it is still an open question how curvature aff…
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…
