O. Gittsovich, R. Hübener, E. Rico, H. J. Briegel

摘要:

本文介绍了二维格点上随机自旋系统的实空间重整化变换。一般的方法制定随机系统和合并两个著名的实空间重整化技术,即强无序重整化技术(SDRT)和承包商重整化(CORE)的结果。在二维随机横场伊辛模型(RTT)上分析了该方法的性能。

英文摘要:

In this paper, we introduce a real-space renormalization transformation for random spin systems on 2D lattices. The general method is formulated for random systems and results from merging two well known real space renormalization techniques, namely the strong disorder renormalization technique (SDRT) and the contractor renormalization (CORE). We analyze the performance of the method on the 2D random transverse field Ising model (RTFIM).
