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 T0 for which linearity holds and it also predicts the maximum superconductive transition temperature Tc. 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.
摘要
层状高温超导铜酸盐中“金属”传导的丝状模型解释了正常态电阻率（霍尔迁移率）在T（T - 2）中呈线性与优化超导性的同时出现。该模型预测了线性关系成立的最低温度T0，并且还预测了最大超导转变温度Tc。该理论摒弃了包括费米液体以及所有其他非渗流模型在内的有效介质近似，转而支持可数的智能基态。
