Phase diagram and fixed points of tensorial Gross-Neveu models in three dimensions
Abstract Perturbing the standard Gross-Neveu model for N 3 fermions by quartic interactions with the appropriate tensorial contraction patterns, we reduce the original U(N 3) symmetry to either U(N) × U(N 2) or U(N) × U(N) × U(N). In the large-N limit, we show that in three dimensions such models ad...
