Mott transition and superconductivity
Laboratoire des Champs Magnétiques Intenses, MPI/CNRS, Grenoble
There exists well established empiric trend - the best superconductors are among the bad conductors, with electrons essentially localized on atomic orbitals. It is just this electronic structure which is a requisite for the metal-insulator transition, predicted by N. Mott. In this lecture I intend to show that the coexistence of these two remarkable phenomena, within the same set of materials, is not accidental.
