内插谢灵顿-柯克帕特里克复制技巧

Interpolating the Sherrington-Kirkpatrick replica trick

Adriano Barra, Francesco Guerra, Emanuele Mingione

摘要:

在过去的几十年里,插值技术已经成为一种强有力的方法,可以在一个简单的数学框架内减轻自旋玻璃的几个属性。然而,对于它们的构造,这些方案自然地被实施到腔场技术中,或者其变体作为随机稳定性或随机重叠结构。然而,第一个也是最著名的方法平均场统计力学与淬火无序是复制技巧。在使用这些方法的模型中,(即,处理挫折和复杂性),可能最有名的是Sherrington-Kirkpatrick自旋玻璃:在本文中,我们很高兴将插值方案应用于复制技巧框架,并直接测试引用的范例模型:有趣的是,这允许容易地获得复制对称控制,并且与破坏的复制边界协同地,获得完整RSB场景的描述,两者都结合了几个小定理。此外,通过将副本$n\in(0,1]$的量作为插值参数(远离其原始解释)来处理,这可以被认为是接近于在非平衡方法中引入的淬火温度,并且在此观点内,可以获得零副本和无限体积极限的伴随交换性的证明。

英文摘要:

The interpolation techniques have become, in the past decades, a powerful approach to lighten several properties of spin glasses within a simple mathematical framework. Intrinsically, for their construction, these schemes were naturally implemented into the cavity field technique, or its variants as the stochastic stability or the random overlap structures. However the first and most famous approach to mean field statistical mechanics with quenched disorder is the replica trick. Among the models where these methods have been used (namely, dealing with frustration and complexity), probably the best known is the Sherrington-Kirkpatrick spin glass: In this paper we are pleased to apply the interpolation scheme to the replica trick framework and test it directly to the cited paradigmatic model: interestingly this allows to obtain easily the replica-symmetric control and, synergically with the broken replica bounds, a description of the full RSB scenario, both coupled with several minor theorems. Furthermore, by treating the amount of replicas $n\in(0,1]$ as an interpolating parameter (far from its original interpretation) this can be though of as a quenching temperature close to the one introduce in off-equilibrium approaches and, within this viewpoint, the proof of the attended commutativity of the zero replica and the infinite volume limits can be obtained.
