Theory of noncentrosymmetric and other unconventional superconductors

现代技术的主要推动力之一是对新材料的研究。超导体是一种不损失任何能量就能导电的材料，这一点尤为重要。目前研究的重点超导材料大多属于非常规超导体。高温铜酸盐和铁酸盐、钌酸锶、重费米子和有机化合物只是其中的一些例子。如果超导体的性质不能用超导的标准微观理论，特别是Bardeen-Cooper-Schrieffer模型来解释，那么超导体就被称为“非常规的”。

One of the major driving forces of modern technology is the research into new materials. Superconductors, which are the materials that can conduct electricity without any energy losses, are of particular importance. The majority of superconducting materials at the focus of current research belong to the class of unconventional superconductors. High-temperature cuprates and iron pnictides, strontium ruthenate, heavy-fermion and organic compounds are just some of the examples. Superconductors are said to be "unconventional" if their properties cannot be explained by the standard microscopic theories of superconductivity, in particular, the Bardeen-Cooper-Schrieffer model.
