Kohn's localization in the insulating state: One-dimensional lattices, crystalline versus disordered

Gian Luigi Bendazzoli, Stefano Evangelisti, Antonio Monari, and Raffaele Resta The qualitative difference between insulators and metals stems from the nature of the low-lying excitations, but alsoaccording to Kohn's theory [W. Kohn, Phys. Rev. 133, A171 (1964)]from a different organization of the electrons in their ground state: electrons are localized in insulators and deloca ... [J. Chem.
