非平均场自旋玻璃的实空间重整化群分析

Real space Renormalization Group analysis of a non-mean field spin-glass

Michele Castellana

摘要:

本文对非平均场自旋玻璃提出了实空间重整化群方法。这种方法已经被设想在努力开发一种替代方法的重整化群方法的基础上的副本方法。实际上,后者的非微扰效应通常是失控的,因此这些方法是不可预测的。相反,我们表明,在这项工作中开发的实空间方法产生精确的预测模型的临界行为和指数。

英文摘要:

A real space Renormalization Group approach is presented for a non-mean field spin-glass. This approach has been conceived in the effort to develop an alternative method to the Renormalization Group approaches based on the replica method. Indeed, non-perturbative effects in the latter are quite generally out of control, in such a way that these approaches are non-predictive. On the contrary, we show that the real space method developed in this work yields precise predictions for the critical behavior and exponents of the model.
