  author={Moshe Kaveh},
Abstract A discussion is presented of localization effects on the conductivity σ of a disordered system. It is shown that for any number of dimensions, the value of σ drops well below the Boltzmann conductivity ne 2τ/m when the disorder is increased. Three arguments are reviewed for power-law corrections to the eigenstates ψ. The power-law correction to ψ yields exactly the same reduction in σ as that obtained from diagrammatic perturbative approaches. The critical behaviour of σ near the… CONTINUE READING
