有机导体（TMTSF）2ClO 4的类D波节结超导性
D-wave-like nodal superconductivity in the organic conductor (TMTSF)2ClO4
摘要：
我们建议理论解释的高上限临界磁场，垂直于导电链，HC 2，实验观察到的超导体（TMTSF）2ClO 4，在单线态超导配对。特别是，我们比较了d波的节点，d波的节点，和s波的超导性的情况下的结果。结果表明，在类d波节点情形下，超导性可以自然地超过轨道上临界磁场和Clogston-Shandrasekhar顺磁极限，并达到实验值Hc 2 = 6 T，而在类d波无节点和s波情形下则相反.在我们看来，所获得的结果强烈支持d-波类节点超导在（TMTSF）2ClO 4，而在一个姐妹化合物，（TMTSF）2 PF 6，我们预计要么存在三重态序参量或三重态和单重态序参量共存。
英文摘要：
We suggest theoretical explanation of the high upper critical magnetic field, perpendicular to conducting chains, Hc2, experimentally observed in the superconductor (TMTSF)2ClO4, in terms of singlet superconducting pairing. In particular, we compare the results of d-wave-like nodal, d-wave-like node-less, and s-wave scenarios of superconductivity. We show that, in d-wave-like nodal scenario, superconductivity can naturally exceed both the orbital upper critical magnetic field and Clogston-Shandrasekhar paramagnetic limit as well as reach experimental value, Hc2 = 6T, in contrast to d-wave-like node-less and s-wave scenarios. In our opinion, the obtained results are strongly in favor of d-wave-like nodal superconductivity in (TMTSF)2ClO4, whereas, in a sister compound, (TMTSF)2PF6, we expect either the existence of triplet order parameter or the coexistence of triplet and singlet order parameters.
