Renormalization Group Study of Anderson Localization in Two Dimensions: Effect of Second-Order Terms

摘要

The localization of electrons moving in a random potential is studied in two dimensions using the real space renormalization group method of Domany and Sarker. The effect of the cell size and of the second-order terms in the perturbation expansion is examined. While the method is not particularly sensitive to the cell size, its results crucially depend on the truncation of the perturbation series. (Atomindex citation 12:633356)
