论文摘要
旋转眼镜的一个重要但略有研究的特性是它们的基态稳定性对于一个或有限数量的耦合变化的稳定性。在较早的工作中表明，如果假定存在多个基础状态，那么其能量差异的波动 - 因此，多个基态的可能性与其基态的稳定性密切相关。在这里，我们研究了两个模型中基态的稳定性，其中一种假定具有与有限尺寸中其他现实的短距离自旋玻璃在质量上相似的基态结构。
An important but little-studied property of spin glasses is the stability of their ground states to changes in one or a finite number of couplings. It was shown in earlier work that, if multiple ground states are assumed to exist, then fluctuations in their energy differences --- and therefore the possibility of multiple ground states --- are closely related to the stability of their ground states. Here we examine the stability of ground states in two models, one of which is presumed to have a ground state structure that is qualitatively similar to other realistic short-range spin glasses in finite dimensions.
