Renormalization group for Anderson localization on high-dimensional lattices
Boris L. Altshuler, Vladimir E. Kravtsov, Antonello Scardicchio +2
We discuss the dependence of the critical properties of the Anderson model on the dimension in the language of -function and renormalization group recently introduced in Re…
