铜氧化物超导体的显著潜在基态

The remarkable underlying ground states of cuprate superconductors

Cyril Proust, Louis Taillefer

摘要:

铜氧化物具有非常强的超导电性。要理解其中的原因,就必须阐明导致配对的电子相互作用的本质。超导性发生在几个潜在的电子相的背景下,包括低掺杂的掺杂莫特绝缘体,高掺杂的奇怪金属,以及介于两者之间的神秘的赝能隙相-在其中出现电荷密度波序的相。在这篇文章中,我们的目标是阐明这些显着的阶段的性质,重点是作为$T \to 0$,实验签名和理论陈述变得更加清晰的限制。因此,我们调查的基态性质的铜酸盐一旦超导性已被删除的应用程序的磁场,并提取其关键的普遍特征。

英文摘要:

Cuprates exhibit exceptionally strong superconductivity. To understand why, it is essential to elucidate the nature of the electronic interactions that cause pairing. Superconductivity occurs on the backdrop of several underlying electronic phases, including a doped Mott insulator at low doping, a strange metal at high doping, and an enigmatic pseudogap phase in between -- inside which a phase of charge-density-wave order appears. In this Article, we aim to shed light on the nature of these remarkable phases by focusing on the limit as $T \to 0$, where experimental signatures and theoretical statements become sharper. We therefore survey the ground state properties of cuprates once superconductivity has been removed by the application of a magnetic field, and distill their key universal features.
