复本对称性破缺的新方法及其在SK模型中的应用

New technique for replica symmetry breaking with application to the SK-model at and near T=0

Manuel J. Schmidt, Reinhold Oppermann

摘要:

我们描述了一种新的方法,它允许在低温下,以及在T=0直接,而不需要近似或缩放假设的高阶复制对称性破缺(RSB)的治疗。它给出了全范围$0\leq a <\infty$内的低温序函数q(a,T),并且是完备的,所有的可观测量都可以由它计算出来.传统的连续制定的有效性和适用性,然后审查,提出了一个新的连续RSB制定。

英文摘要:

We describe a novel method which allows the treatment of high orders of replica-symmetry-breaking (RSB) at low temperatures as well as at T=0 directly, without a need for approximations or scaling assumptions. It yields the low temperature order function q(a,T) in the full range $0\leq a <\infty$ and is complete in the sense that all observables can be calculated from it. The behavior of some observables and the finite RSB theory itself is analyzed as one approaches continuous RSB. The validity and applicability of the traditional continuous formulation is then scrutinized and a new continuous RSB formulation is proposed.
