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.

掺杂铜酸盐中的超导体到金属的转变

我们提供了一个理论框架，用于了解掺杂掺杂的量子超导体到金属跃迁附近的超掺杂铜酸盐高温超导体的常态和超导态的行为。我们关注的关键因素是d波配对，平坦的抗结离散度和无序性。即使对于均匀无序，它们也导致有效的颗粒超导相关性和超导转变温度，该温度主要由超流体刚度而不是配对尺度决定。
