陶瓷高温超导体的拓扑理论

Topological Theory of Ceramic High Temperature Superconductors

J. C. Phillips

摘要:

最佳掺杂陶瓷超导体(铜酸盐,磷属元素化物,.)表现出的转变温度Tc比强耦合金属超导体如Pb(Tc= 7.2K,Eg/kTc = 4.5)大得多,并且表现出许多普遍的特征,这些特征似乎与基于吸引性电子-声子配对相互作用的BCS超导理论相矛盾。在这里,我认为,这种自相矛盾的简单性是合理的解决框架内的Pauling-Phillips自组织,硬连线的掺杂剂网络模型的陶瓷超导体,以前解释了许多功能的正常状态下的这些材料的输运性质,并成功地预测严格的最低上限Tc的铜酸盐和磷族元素化物的家庭。

英文摘要:

Optimally doped ceramic superconductors (cuprates, pnictides, ...) exhibit transition temperatures Tc much larger than strongly coupled metallic superconductors like Pb (Tc= 7.2K, Eg/kTc = 4.5), and exhibit many universal features that appear to contradict the BCS theory of superconductivity based on attractive electron-phonon pairing interactions. Here I argue that this paradoxical simplicity is plausibly resolved within the framework of the Pauling-Phillips self-organized, hard-wired dopant network model of ceramic superconductors, which has previously explained many features of the normal-state transport properties of these materials and successfully predicted strict lowest upper bounds for Tc in the cuprate and pnictide families.
