Large-N Analysis of Three Dimensional Nonlinear Sigma Models
Kiyoshi Higashijima, Etsuko Itou, Makoto Tsuzuki
Non-perturbative renormalization group approach suggests that a large class of nonlinear sigma models are renormalizable in three dimensional space-time, while they are non-renorma…

New Conformal Field Theories with Anomalous Dimensions
Etsuko Itou
We find a class of fixed point theory for 2- and 3-dimensional non-linear sigma models using Wilsonian renormalization group (WRG) approach. In 2-dimensional case, the fixed point…
