CONDENSED MATTER
Universal temperature dependence of the conductivity of a strongly disordered granular metal
A. R. Akhmerov, A. S. Ioselevich L. D. Landau Institute for Theoretical Physics
Abstract:
A disordered array of metal grains with large and random intergrain conductances is studied within the one-loop accuracy renormalization group approach. While at low level of disorder the dependence of conductivity on $\log T$ is nonuniversal (it depends on details of the array's geometry), for strong disorder this dependence is described by a universal nonlinear function, which depends only on the array's dimensionality. In two dimensions this function is found numerically. The dimensional crossover in granular films is discussed.
