概要
- 論文の詳細を見る
The disordered ground-state occurring at the phase boundary are discussed for the one-dimensional Ising system with the coupling constants J_1, J_2,・・・, J_r. The zero-point entropy and the Curie constant in the close vicinity of 0°K are evaluated exactly for a disordered point satisfied by J_1+2J_2+・・・+rJr=0. The correlation function at the same point is shown to have a longer period than in the contiguous ordered state. The field-induced disorder, which is pointed out to exist possibly under certain conditions, is also exactly discussed.
