- 論文の詳細を見る
Quantum statistical mechanics of soliton systems is developed in the path integralformalizm by making use of the non-canonical collective coordinate method. Thefree energy is calculated in the ideal-gas approximation up to the order of two-loop.Explicit calculations are given for the sine-Gordon model. The classical limit of thepresent quantum calculation agrees with the exact result of the low-temperature expansion of the transfer-integral method. Numerical calculation reveals the quantumeffect on the specific heat.
