On the Ising model with random boundary condition

A. C. D. van Enter, K. Netocny, H. G. Schaap

摘要:

研究了二维伊辛模型在可能强随机边界条件下的无限体积极限行为。该模型表现出混乱的尺寸依赖性在低温下,我们证明了“+”和“-”相是唯一几乎肯定的极限吉布斯措施,假设该限制是沿着一个足够稀疏的序列的平方。特别是,我们提供了一个参数,以表明在一个足够大的体积下,一个典型的自旋配置在一个典型的边界条件不包含接口。为了排除混合物作为可能的极限点,进行详细的多尺度轮廓分析。

英文摘要:

The infinite-volume limit behavior of the 2d Ising model under possibly strong random boundary conditions is studied. The model exhibits chaotic size-dependence at low temperatures and we prove that the `+' and `-' phases are the only almost sure limit Gibbs measures, assuming that the limit is taken along a sparse enough sequence of squares. In particular, we provide an argument to show that in a sufficiently large volume a typical spin configuration under a typical boundary condition contains no interfaces. In order to exclude mixtures as possible limit points, a detailed multi-scale contour analysis is performed.
