摘要翻译:
我们应用一种新的方法(在第一部分中介绍)来求解几个小世界模型:Viana-Bray模型(可以看作是0维或无限维的小世界模型)、一维链式小世界模型和一般维的小世界球面模型。特别地,我们详细分析了具有负短程耦合的一维链状小世界模型,表明在这种情况下,除了一个二级自旋玻璃相变之外,还有两个临界温度对应于一级或二级相变。

英文摘要:
We apply a novel method (presented in part I) to solve several small-world models for which the method can be applied analytically: the Viana-Bray model (which can be seen as a 0 or infinite dimensional small-world model), the one-dimensional chain small-world model, and the small-world spherical model in generic dimension. In particular, we analyze in detail the one-dimensional chain small-world model with negative short-range coupling showing that in this case, besides a second-order spin glass phase transition, there are two critical temperatures corresponding to first- or second-order phase transitions.
