Localization in an almost periodically modulated array of potential barriers

  • 1. Northeastern University, Physics Department, Boston, Massachusetts 02115

Description

It is argued that an array of potential barriers modulated in position and strength in a manner incommensurate with the barrier spacing can be replaced by a delta-function Kronig-Penny model. With this equivalence it is shown, by using renormalization-group arguments as well as known results from other calculations, that this model possesses both localized and extended states separated by mobility edges
