20 08 Large N transition in the 2 D SU ( N ) xSU ( N ) nonlinear sigma model
We consider the characteristic polynomial associated with the smoothed two point function in two dimensional large N principal chiral model. We numerically show that it undergoes a transition at a critical distance of the order of the correlation length. The transition is in the same universality class as two dimensional large N QCD.

متن کاملLarge N Limit on Langevin Equation : Two - Dimensional Nonlinear Sigma Model
1. Abstract We study the stochastic quantization of two-dimensional nonlinear sigma model in the large N limit. Our main tool is the effective Langevin equation with which we investigate nonperturbative phenomena and derive the results which are same as the path integral approach gives.

15 صفحه اولLarge-N Analysis of Three Dimensional Nonlinear Sigma Models
Non-perturbative renormalization group approach suggests that a large class of nonlinear sigma models are renormalizable in three dimensional space-time, while they are nonrenormalizable in perturbation theory. N = 2 supersymmetric nonlinear sigma models whose target spaces are Einstein-Kähler manifolds with positive scalar curvature belongs to this class. hermitian symmetric spaces, being homo...
