From Power-Localized to Extended States in a Class of One-Dimensional Disordered Systems
Abstract
We study a one-dimensional random Kronig-Penney model in the presence of a constant electric field. We rigorously prove for the first time the existence of a transition between a regime of extended states for large field and a regime of power-localized states for small field. There the large-distance behavior of the states is |x|^(−α(F)) with α(F) ∼ C/F for small field F, confirming a numerical computation of Soukoulis et al.
