Quantum model for the O-Cu-O cluster inside YBCO superconductor

We study a simple quantum model for the O-Cu-O cluster inside the YBCO superconductor. First we reproduce PRL 68, 3236 and J. Sup. Nov. Mag. 20, 603. Afterwards we will study a reigmen with slower hopping electrons (i. e. larger interatomic distances) which could be related to other compounds.我们针对钇钡铜氧（YBCO）超导体内部的氧-铜-氧（O-Cu-O）团簇，研究了一款简易量子模型。首先，我们复现了《物理评论快报》（PRL）第68卷第3236页以及《超导电性与新型磁学期刊》（J. Sup. Nov. Mag.）第20卷第603页的研究成果。后续我们将对跳迁电子速率更低（对应更大原子间距）的态域展开研究，该态域或与其他超导化合物相关。
