超导之谜:有胶还是没有胶?

The Mystery of Superconductivity: Glue or No Glue?

X. Q. Huang

摘要:

在这项研究中,一个可能的非准粒子胶的超导性的传统和非传统的超导体探索在一个纯电子图片。结果表明,由于电磁相互作用,运动的电子可以自组织成准一维实空间电荷条纹,进而形成三角或四角对称的涡旋晶格.讨论了电荷条纹、库珀对和Peierls相变之间的关系。所提出的超导机制(胶)可能适用于一维和二维超导体。我们还认为掺杂超导体的最高临界温度最有可能在Mott金属-绝缘体转变附近达到。

英文摘要:

In this study, a possible non-quasiparticle glue for superconductivity of both conventional and unconventional superconductors is explored in a pure electron picture. It is shown clearly that the moving electrons due to the electromagnetic interaction can self-organize into some quasi-one-dimensional real-space charge stripes, which can further form some thermodynamically stable vortex lattices with trigonal or tetragonal symmetry. The relationships among the charge stripes, the Cooper pairs and the Peierls phase transition are discussed. The suggested mechanism (glue) of the superconductivity may be valid for the one- and two-dimensional superconductors. We also argue that the highest critical temperature of the doped superconductors is most likely to be achieved around the Mott metal-insulator transition.
