树上自旋玻璃基态的唯一性和非唯一性

Uniqueness and Non-Uniqueness for Spin-Glass Ground States on Trees

Johannes Bäumler

摘要:

我们考虑在温度$T = 0$下的自旋玻璃,其中底层图是局部有限树。我们证明了一个广泛的耦合分布,基态的唯一性是等价的最大流从任何顶点$\infty$(其中每个边缘$e$有能力$|J_{e}|$)等于零,这是等价于递归的简单随机游动的树。

英文摘要:

We consider a Spin Glass at temperature $T = 0$ where the underlying graph is a locally finite tree. We prove for a wide range of coupling distributions that uniqueness of ground states is equivalent to the maximal flow from any vertex to $\infty$ (where each edge $e$ has capacity $|J_{e}|$) being equal to zero which is equivalent to recurrence of the simple random walk on the tree.
