理解铜氧化物超导体中的各种竞争相是一个长期存在的具有挑战性的问题。最近的研究表明,轨道自由度,无论是Cu e g轨道和O p轨道,是一个统一的理解铜酸盐超导体,包括材料依赖性的关键因素。在这里,我们研究一个四频段
Understanding the various competing phases in cuprate superconductors is a long-standing challenging problem. Recent studies have shown that orbital degrees of freedom, both Cu e g orbitals and O p orbitals, are a key ingredient for a unified understanding of cuprate superconductors, including the material dependence. Here we investigate a four-band
