论文摘要
我们提出了一个理论框架，用于理解在掺杂型量子量子超导体到金属过渡的附近过度库层高温超导体的正常和超导状态的行为。我们关注的关键成分是D波配对，扁平的抗邻近分散体和混乱。即使对于同质性疾病，这些也会导致有效的颗粒超导相关性和超导过渡温度在很大程度上由超流体刚度而不是配对量表确定。
We present a theoretical framework for understanding the behavior of the normal and superconducting states of overdoped cuprate high temperature superconductors in the vicinity of the doping-tuned quantum superconductor-to-metal transition. The key ingredients on which we focus are d-wave pairing, a flat antinodal dispersion, and disorder. Even for homogeneous disorder, these lead to effectively granular superconducting correlations and a superconducting transition temperature determined in large part by the superfluid stiffness rather than the pairing scale.
