Two-Dimensional CP^2 Model with θ-Term and Topological Charge Distributions
スポンサーリンク
概要
- 論文の詳細を見る
Topological charge distributions in the two-dimensional CP^2 model with the θ-term are calculated. In strong coupling regions, the topological charge distribution is approximately given by a Gaussian form as a function of the topological charge, and this behavior leads to a first order phase transition at θ=π. In weak coupling regions, this distribution exhibits nonGaussian form, and the first order phase transition disappears. The free energy as a function of θ displays "flattening" behavior at θ=θ_f < π when we calculate the free energy directly from the topological charge distribution. A possible origin of this flattening phenomenon is proposed.
