摘要翻译:
结合两种精确分析方法,研究了绳梯上自旋1/2和自旋-S(S>1/2)Ising混合模型。通过装饰-迭代映射变换,将该混合自旋系统转化为简单的自旋1/2Ising模型,然后用标准传递矩阵法对其进行精确求解。重点讨论了零场比热的热变化。

英文摘要:
The mixed spin-1/2 and spin-S (S>1/2) Ising model on a rope ladder is examined by combining two exact analytical methods. By the decoration-iteration mapping transformation, this mixed-spin system is firstly transformed to a simple spin-1/2 Ising model on the two-leg ladder, which is then exactly solved by the standard transfer-matrix method. The thermal variations of the zero-field specific heat are discussed in particular.
