一类Curie-Weiss模型

A certain class of Curie-Weiss models

Giuseppe Genovese, Adriano Barra

摘要:

利用平均场自旋系统的统计力学和粘性液体的分析力学之间的形式类比(最初由Francesco Guerra提出,后来由作者发展),我们给出了一类广义自旋变量的Curie Weiss模型的自由能的热力学极限和临界行为.然后,用同样的技术,我们给出了一个完整的图片的二分居里-外斯模型,处理同一类的广义自旋。最后,我们进一步分析了后者的极小极大原理的存在,它反映了标准的变分原理的正则热力学时,推广到多个相互作用的缔约方。

英文摘要:

By using a formal analogy between statistical mechanics of mean field spin systems and analytical mechanics of viscous liquids -at first pointed out by Francesco Guerra, then recently developed by the authors- we give the thermodynamic limit of the free energy and the critical behavior of Curie Weiss models for a certain class of generalized spin variables. Then, with the same techniques, we give a complete picture of the bipartite Curie-Weiss model, dealing with the same class of generalized spins. Ultimately we analyze further the existence of a minmax principle for the latter which mirrors the standard variational principle of canonical thermodynamics when generalized to multiple interacting parties.
