3D Anderson transition for two electrons in 2D
arXiv:cond-mat/9902246
Abstract
It is shown that the Coulomb interaction can lead to delocalization of two electron states in two-dimensional (2D) disordered potential in a way similar to the Anderson transition in three dimensions (3D). At fixed disorder strength the localized phase corresponds to low electron density and large value of parameter r_s.
