提出了一种非平均场自旋激光的实空间重整化群方法。这种方法是在努力开发一种替代基于复制方法的重整化群方法的方法时构思出来的。事实上，后者中的非扰动效应通常是完全失控的，在这种方式下，这种方法是不可预测的。相反，我们表明，这里提出的实空间方法给出了模型临界行为和指数的精确预测。版权所有(C)Epla，2011
A real-space Renormalization Group approach is presented for a non-mean-field spin-lass. 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 such approaches are non-predictive. On the contrary, we show that the real-space method presented here yields a precise prediction of the critical behavior and exponents of the model. Copyright (C) EPLA, 2011
