Theory of a Fermi glass

摘要: We construct a theory for localized electrons in disordered solids similar spirit and intent to the Fermiliquid of Landau. That is, low temperatures excitation energies small compared Fermi energy, may be viewed as forming gas quasiparticles. The phenomenological is presented applications are made both equilibrium time-dependent properties glass. A microscopic justification quasiparticle picture by an examination single-particle Green's function interacting system. collective glass examined studing Bethe-Salpeter equation satisfied four-point vertex particle-hole scattering. This leads identification effective interaction between quasiparticles with certain limit transport used study phenomena.
