Large-N ℂℙ N −1 sigma model on a Euclidean torus: uniqueness and stability of the vacuum
Abstract In this paper we examine analytically the large-N gap equation and its solution for the 2D ℂℙ N −1 sigma model defined on a Euclidean spacetime torus of arbitrary shape and size (L, β), β being the inverse temperature. We find that the system has a unique homogeneous phase, with the ℂℙ N −1...
