猝灭随机伊辛模型的关联函数的几个不等式

Some inequalities for correlation functions of Ising models with quenched randomness

Manaka Okuyama, Masayuki Ohzeki

摘要:

相关不等式在铁磁模型的分析中起着重要的作用,但在自旋玻璃模型中还没有建立。本文研究了具有猝灭随机性的伊辛模型的相关不等式,其中相互作用的分布是对称的.所得的不等式可以看作是以前只限于自旋集的局部能量的结果到自旋集对的局部能量的推广。此外,我们还得到了一些非对称分布的相关不等式。

英文摘要:

Correlation inequalities have played an essential role in the analysis of ferromagnetic models but have not been established in spin glass models. In this study, we obtain some correlation inequalities for the Ising models with quenched randomness, where the distribution of the interactions is symmetric. The acquired inequalities can be regarded as an extension of the previous results, which were limited to the local energy for a spin set, to the local energy for a pair of spin sets. Besides, we also obtain some correlation inequalities for asymmetric distribution.
