量子网络模型与经典局域化问题

Quantum Network Models and Classical Localization Problems

John Cardy

摘要:

本文综述了在适当的二维晶格上描述自旋量子霍尔平台跃迁的C类量子网络模型。然而,在一般的一类图上,这些模型的许多观测值可以映射到随机环境中的经典行走,从而涉及量子和经典局部化问题。在许多情况下,通过与相关的渗流问题的关系,在二维和三维中,可以对后者做出严格的陈述。

英文摘要:

A review is given of quantum network models in class C which, on a suitable 2d lattice, describe the spin quantum Hall plateau transition. On a general class of graphs, however, many observables of such models can be mapped to those of a classical walk in a random environment, thus relating questions of quantum and classical localization. In many cases it is possible to make rigorous statements about the latter through the relation to associated percolation problems, in both two and three dimensions.
