概要
- 論文の詳細を見る
A system with Hamiltonian H_0 is assumed to undergo a phase transition at transition temperature T_0 When a small perturbation term λH´ is added to H_0, the transition temper ature will depend on the coupling parameter λ and the critical indices will in general be changed. The change induced by the application of λH´ is classified into three types, and these types are discussed for the cases of anisotropic Ising ferromagnets by means of ther modynamic perturbation theory and scaling law equation for spin correlation functions.
