Abstract

Description

Anderson transition in three-dimensional systems is investigated using renormalization group theory. $β$-function of a very simple form is derived from a self-consistent consideration, and it gives a value $1+1/\sqrt{3}=1.58$ for the critical index of the transition, which is very close to those obtained by numerical studies.
