THE METAL-INSULATOR TRANSITION IN THE EXPANDED METALS

Abstract
The Landau theory of phase transition is extended to include the singular free-energy due to a metal-insulator (MI) transition and to discuss the condensation caused by this. Some relation is pointed out between the behaviours in T > Tc and those in T < Tc. One sees what type of singularity the idealized model of the electron system is desired to derive in order to explain the experimental facts in the supercritical region.
