Pierluigi Contucci, Cristian Giardina, Claudio Giberti, Giorgio Parisi, Cecilia Vernia

摘要:

研究了具有Bernoulli随机耦合的三维Edwards-Anderson模型的低温相。我们发现,在一个固定的值$Q$的重叠的模型满足聚类属性:两个局部重叠之间的连接关联函数衰减为幂,其指数是独立的$Q$的所有$0\le |Q| < q_{EA}$。我们的研究结果与RSB理论一致,并表明重叠是一个很好的序参量。

英文摘要:

We investigate the low temperature phase of three-dimensional Edwards-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 decay as a power whose exponent is independent of $Q$ for all $0\le |Q| < q_{EA}$. Our findings are in agreement with the RSB theory and show that the overlap is a good order parameter.
