研究了具有Bernoulli随机耦合的三维Edward-Anderson模型的低温相。我们发现，在一个固定值Q的重叠，该模型满足聚类性质：两个局部重叠之间的连接相关函数具有幂律衰减。我们的研究结果与副本对称性破缺理论一致，并表明重叠是一个很好的序参量。
We investigate the low temperature phase of the three dimensional Edward-Anderson model with Bernoulli random couplings. We show that, at a fixed value Q of the overlap, the model fulfills the clustering property: The connected correlation functions between two local overlaps have power law decay. Our findings are in agreement with the replica symmetry breaking theory and show that the overlap is a good order parameter.
