Webb10 mars 2006 · The qualitative difference between insulators and conductors not only manifests itself in the excitation spectra but also—according to Kohn's theory [Phys. Rev. 133, A171 (1964)]—in a different organization of the electrons in their ground state: the wave function is localized in insulators and delocalized in conductors. Such localization, … WebbStrongly correlated materials are a wide class of compounds that include insulators and electronic materials, and show unusual (often technologically useful) electronic and magnetic properties, such as metal-insulator transitions, heavy fermion behavior, half-metallicity, and spin-charge separation.
