All orders analysis of three dimensional CP^(N-1) model in 1/N-expansion
Kiyoshi Higashijima, Takahiro Nishinaka
The renormalizability of the three dimensional supersymmetric CP^(N - 1) model is discussed in the 1/N-expansion method, to all orders of 1/N. The model has N copies of the dynamic…
Supersymmetric three dimensional conformal sigma models
Takeshi Higashi, Kiyoshi Higashijima, Etsuko Itou
We construct supersymmetric conformal sigma models in three dimensions. Nonlinear sigma models in three dimensions are nonrenormalizable in perturbation theory. We use the Wilsonia…
Three dimensional conformal sigma models
Takeshi Higashi, Kiyoshi Higashijima, Etsuko Itou
We construct novel conformal sigma models in three dimensions. Nonlinear sigma models in three dimensions are nonrenormalizable in perturbation theory. We use Wilsonian renormaliza…
Wilsonian renormalization group approach to the lower dimensional nonlinear sigma models
Kiyoshi Higashijima, Etsuko Itou
In this paper, we study three dimensional NLMs within two kind of nonperturbative methods; WRG and large-N expansion. First, we investigate the renormalizability of some NLMs…
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…
Three Dimensional Nonlinear Sigma Models in the Wilsonian Renormalization Method
K. Higashijima, E. Itou
The three dimensional nonlinear sigma model is unrenormalizable in perturbative method. By using the function in the nonperturbative Wilsonian renormalization group method, we…
