论文摘要
最佳和过量的铜酸盐超导体（包括DC和光学传输响应）的各种低温，正常状态的特性足够异常，以致它们似乎与任何准粒子描述都不一致。但是，我们通过显式结构表明，最突出的现象可以在带有局部的“奇怪散射器”的系统中解释，并嵌入带有常规准粒子描述的费米液体中。这样的散射器可能源自与具有短距离电荷相关性的电子玻璃状态相关的“两级系统”。
A variety of low-temperature, normal-state properties of optimally and overdoped cuprate superconductors, including the DC and optical transport responses, are sufficiently anomalous that they might seem to be inconsistent with any quasiparticle description. However, we show by explicit construction that the most salient phenomena can be accounted for in a system with localized "strange scatterers" embedded into a Fermi liquid with a conventional quasiparticle description. Such scatterers could originate from "two-level systems" associated with an electronic glassy state with short-range charge-order correlations.
