N = ∞ phase transition in a class of exactly soluble model lattice gauge theories
Abstract
An exactly soluble class of model U( N) lattice gauge theories is considered. The ground state is discussed as a separable N-fermion problem solved by mathieu functions. Some exact correlation functions are presented. The N = ∞ limit exhibits a third order phase transition demarcating the strong and weak phases at ( g2N) -1 ≈ 0.55.
