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'.

在元素汞中发现超导性 100 年后，我们拥有了无数的超导材料家族，每一种材料似乎彼此之间都没有什么共同点。超导现象全都与电荷的运动有关，甚至我们对这种非凡物质状态的机制的理解，至少对于所谓的传统超导体来说，也是通过电荷波动配对的。相比之下，对于较新的超导体，当前有关其机制的许多想法都集中在作为“配对粘合剂”的“自旋涨落”上。
