Glassy Behavior of Electrons as a Precursor to the Localization Transition

Abstract

A theoretical model is presented, describing the glassy freezing of electrons in the vicinity of disorder driven metal-insulator transitions. Our results indicate that the onset of glassy dynamics should emerge before the localization transition is reached, thus predicting the existence of an intermediate metallic glass phase between the normal metal and the insulator.Comment: Six pages, one EPS figure; proceedings of EP2DS-1
