Superconductivity in layered cuprates is induced by doping holes into a parent antiferromagnetic insulator. It is now recognized that another common emergent order involves charge stripes, and our understanding of the relationship between charge stripes and superconductivity has been evolving. Here we review studies of 214 cuprate families obtained by doping La₂CuO₄. Charge-stripe order tends to compete with bulk superconductivity; nevertheless, there is plentiful evidence that it coexists with two-dimensional superconductivity. This has been interpreted in terms of pair-density-wave superconductivity, and the perspective has shifted from competing to intertwined orders. In fact, a new picture of superconductivity based on pairing within charge stripes has been proposed, as we discuss.

铜酸盐中电荷顺序的超导性

层状铜酸盐的超导性是通过将空穴掺杂到母体反铁磁绝缘体中来引起的。现在人们认识到另一种常见的涌现顺序涉及电荷条纹，我们对电荷条纹与超导性之间关系的理解一直在发展。在这里，我们回顾了通过掺杂 La ₂ CuO ₄获得的 214 个铜酸盐家族的研究. 电荷条序倾向于与体超导竞争；尽管如此，有大量证据表明它与二维超导共存。这已被解释为对密度波超导性，视角已从竞争转变为相互交织的秩序。事实上，正如我们所讨论的，已经提出了一种基于电荷带内配对的超导性新图。
