超导现象的特征是零电阻和完全抗磁性。自从1911年水银被发现在低温下是超导体以来,超导体的物理性质及相关的超导电性机理问题就一直是物理学研究的重要方向之一。描述常规的低温超导体的电-声子超导电性理论是巴丁、库珀和施里弗于1957年建立的。然而,随着近几十年来新超导体的不断出现,人们惊奇地发现,一些超导体的超导电性不能用传统的电-声子超导电性理论解释,于是把这类超导体统称为非常规超导体。
虽然在非常规超导体中同样是由电子对的玻色凝聚而形成没有电阻的超导态,但是其配对的对称性上有s-波,p-波,d-波等以及自旋单重态和三重态的选择。特别是非常规超导体表现出一些新奇的物理性质。例如:p-波超导体中有非平庸拓扑相,会出现马约纳拉边缘态。1986 年发现的铜氧化物高温超导体的超导态具有d-波对称性,其电子对的形成与磁性涨落密切相关。20多年来,钌酸锶一直被认为是 p-波超导体的主要候选者之一,但是近期的一系列实验研究对这一可能的电子配对形式提出了挑战。近10余年以来被相继发现的铁基超导体和镍基超导体则进一步促进了非常规超导电性的研究。更特别的是,人们发现一些含有碳或碳氢元素的有机化合物可能是非常规超导体,同时人们也一直在石墨烯及其类似的二维量子材料中寻找超导电性,已有理论预测掺杂石墨烯中可以实现新奇的手性d-波超导体。考虑非常规超导电性研究中不断出现的新进展,我们认为很有必要把国内外的最新研究成果集中起来并介绍给相关研究人员。
本专题收录了介绍非常规超导电性研究进展的综述和近期国内非常规超导电性研究领域的部分最新实验和理论研究原创论文,研究内容涉及铜氧化物高温超导体、铁基超导体、镍基超导体、钌酸锶超导体和类石墨烯材料中各种新奇的物理性质及可能的超导电性机理。希望本专题能够对国内外相关研究人员有所帮助和启示,并进一步推动非常规超导电性研究的进展。
