中文摘要
在元素水星中发现超导电性100年后,我们已经有了无数的超导材料家族,每一种超导材料似乎彼此几乎没有什么共同之处。超导现象完全是关于电荷的运动,就连我们对这种非凡状态的物质机制的理解,至少对所谓的传统超导体来说,也是关于通过电荷波动进行配对的。相比之下,对于较新的超导体,目前关于其机制的许多想法都围绕着“自旋涨落”这一“配对胶”展开。
英文摘要
100 years after the discovery of superconductivity in elemental Mercury, we have innumerable families of superconducting materials, each of which seems to have little in common with one another. The phenomenon of superconductivity is all about the movement of charge, and even our understanding of the mechanism for this remarkable state of matter, at least for so-called conventional superconductors, is about pairing through charge fluctuations. In contrast, for newer superconductors, many of the current ideas about the mechanism involved center around `spin fluctuations' as the `pairing glue'.
