Phys. Rev. B 70, 205120 (2004) [5 pages]Universal description of granular metals at low temperatures: Granular Fermi liquidReceived 10 August 2004; published 16 November 2004 We present a unified description of the low-temperature phase of granular metals that reveals a striking generality of the low-temperature behaviors. Our model explains the universality of the low-temperature conductivity that coincides exactly with that of the homogeneously disordered systems and enables a straightforward derivation of low-temperature characteristics of disordered conductors. © 2004 The American Physical Society URL:
