关于随机场伊辛模型中关联的衰减

On the decay of correlations in the random field Ising model

Sourav Chatterjee

摘要:

在1990年的一篇著名论文中,Aizenman和Wehr证明了二维随机场伊辛模型在任何温度下都有唯一的无限体积吉布斯态。证明是遍历理论的性质,并没有提供任何定量的信息。本文证明了Aizenman-Wehr定理的第一个定量版本。证明引入了一种新的方法来证明衰变的相关性,可能是有趣的本身。一个相当详细的草图背后的主要思想的证明也包括在内。

英文摘要:

In a celebrated 1990 paper, Aizenman and Wehr proved that the two-dimensional random field Ising model has a unique infinite volume Gibbs state at any temperature. The proof is ergodic-theoretic in nature and does not provide any quantitative information. This article proves the first quantitative version of the Aizenman-Wehr theorem. The proof introduces a new method for proving decay of correlations that may be interesting in its own right. A fairly detailed sketch of the main ideas behind the proof is also included.
