我们讨论自旋玻璃中的界面。我们提出了新的理论结果和数值方法表征重叠界面和自旋玻璃相在扩展无序系统的稳定性。我们使用这个定义来表征分级自旋玻璃模型的低温相。我们使用副本对称性破缺理论来评估重叠接口的成本，这在这些模型中是特别简单的。我们的数值模拟结果与理论预测的比较显示出良好的一致性。
We discuss interfaces in spin glasses. We present new theoretical results and a numerical method for characterizing overlap interfaces and the stability of the spin-glass phase in extended disordered systems. We use this definition to characterize the low temperature phase of hierarchical spin-glass models. We use the replica symmetry breaking theory to evaluate the cost for an overlap interface, which in these models is particularly simple. A comparison of our results from numerical simulations with the theoretical predictions shows good agreement.
