概要
- 論文の詳細を見る
The quantum sine-Gordon model in two spatial dimensions is studied using the method of Wilson's renormalization group with the aid of the Feynman path integral. The Kosterlitz-Thouless transition temperature is calculated and shown to be lower than that of the corresponding classical sine-Gordon model. A classical film system is shown to correspond to the quantum sine-Gordon model and its transition temperature is shown to increase with increasing thickness. Applicability of our treatment is examined.
