概要
- 論文の詳細を見る
The collective coordinate method is applied to develop the statistical mechanics ofsoliton systems. The present perturbation expansion is a direct extention of that donein the quantum field theory and is applicable to the quantum case. A new type ofdivergence which has never met so far in the many body theory appears in the presenttreatment but it can be removed by an appropriate treatment giving reasonableresults. As the first paper of this series the classical case is investigated and explicitcalculation is done in the classical sine-Gordon model. The results agree with theexact low temperature corrections obtained by the transfer-integral method and withthose obtained by Miyashita and Maki who applied the collective coordinate ap-proach in a different way.
