$2d$远程伊辛模型不存在Dobrushin态

Absence of Dobrushin states for $2d$ long-range Ising models

Loren Coquille, Aernout C. D. van Enter, Arnaud Le Ny, Wioletta M. Ruszel

摘要:

我们考虑了具有$J_{xy}\sim|x-y|^{-α}$和$α>2$形式的长程对相互作用的二维伊辛模型,主要是当$J_{xy} \geq 0$。我们表明,Dobrushin状态(即极端的非平移不变吉布斯态选择的混合$\pm$ -边界条件)不存在。我们讨论可能的扩展,这个结果的方向的Aizenman-Higuchi定理,或有关波动的接口。我们还提到刚性界面的存在,在两个长程各向异性的上下文中。

英文摘要:

We consider the two-dimensional Ising model with long-range pair interactions of the form $J_{xy}\sim|x-y|^{-α}$ with $α>2$, mostly when $J_{xy} \geq 0$. We show that Dobrushin states (i.e. extremal non-translation-invariant Gibbs states selected by mixed $\pm$-boundary conditions) do not exist. We discuss possible extensions of this result in the direction of the Aizenman-Higuchi theorem, or concerning fluctuations of interfaces. We also mention the existence of rigid interfaces in two long-range anisotropic contexts.
