Filamentary microstructure and linear temperature dependence of normal state transport in optimized high temperature superconductors

Abstract
A filamentary model of “metallic” conduction in layered high temperature superconductive cuprates explains the concurrence of normal state resistivities (Hall mobilities) linear in T (T −2) with optimized superconductivity. The model predicts the lowest temperature T 0 for which linearity holds and it also predicts the maximum superconductive transition temperature T c. The theory abandons the effective medium approximation that includes Fermi liquid as well as all other nonpercolative models in favor of countable smart basis states.
