A survey of large N continuum phase transitions

High Energy Physics - Lattice 2009-04-14 v2 High Energy Physics - Theory

Abstract

The main focus of this talk is the physics of large N QCD on a continuum torus. A cascade of phase transitions associated with the breaking of U(1) symmetries will be discussed. The continuum Wilson loop as a function of its area will be discussed along with its universality properties and the associated double scaling limit. Some recent progress in twisted Eguchi-Kawai is presented. Gauge field topology and θ\theta vacuua are also discussed in the context of large N gauge theories. Phase transitions in 2D large N principal chiral models are compared with similar transitions in large NN gauge theories. Finally, connections to some topics in string theory and gravity are briefly described.
