Delocalization for the 3D discrete random Schrödinger operator at weak disorder
We apply a recently developed approach (Liaw 2013 J. Stat. Phys. 153 1022–38) to study the existence of extended states for the three-dimensional discrete random Schrödinger operator at small disorder. The conclusion of delocalization at small disorder agrees with other numerical and experimental observations (see e.g. (Lagendijk et al 2009 …
