Non-Abelian Combinatorial Gauge Theory
Hongji Yu, Dmitry Green, Claudio Chamon · arXiv (Cornell University) · 2024
Building on the principle of combinatorial gauge symmetry, lattice gauge theories can be formulated with only one- and two-body interactions that ensure the exact realization of the symmetry rather than its approximate emergence in a perturbative regime. This paper extends the framework to encompass generic non-Abelian finite gauge groups by expanding on previous work that developed the theory for finite Abelian gauge groups and presented one non-Abelian example.
