短程自旋玻璃在半平面中基态的唯一性

Uniqueness of Ground States for Short-Range Spin Glasses in the Half-Plane

Louis-Pierre Arguin, Michael Damron, Charles Newman, Daniel Stein

摘要:

我们考虑半平面$Z \times Z^+$上的Edwards-AndersonIsing自旋玻璃模型,对于i.i.d.最近邻耦合无限体积联合分布$K(J,α)$耦合J和基态对$α$周期性(分别,自由)的边界条件,在水平(分别,垂直)坐标被证明是存在的,而不需要后续的限制。我们的主要结果是,对于几乎每一个J,条件分布$K(α|J)$支持一个单一的基态对。

英文摘要:

We consider the Edwards-Anderson Ising spin glass model on the half-plane $Z \times Z^+$ with zero external field and a wide range of choices, including mean zero Gaussian, for the common distribution of the collection J of i.i.d. nearest neighbor couplings. The infinite-volume joint distribution $K(J,α)$ of couplings J and ground state pairs $α$ with periodic (respectively, free) boundary conditions in the horizontal (respectively, vertical) coordinate is shown to exist without need for subsequence limits. Our main result is that for almost every J, the conditional distribution $K(α|J)$ is supported on a single ground state pair.
