摘要翻译:
我们描述了一种新的方法,它允许在低温下以及在t=0时直接处理高阶复制品对称性破缺(RSB),而不需要近似或标度假设。它得到了整个范围内的低温阶函数q(a,T),并且是完全的,所有的可观测项都可以从它中计算出来。当一个接近连续RSB时,分析了一些可观测项的行为和有限RSB理论本身。在此基础上,考察了传统连续公式的有效性和适用性,提出了一种新的连续RSB公式。

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.
