我们发展了一种研究巡游电子体系中间接共振非弹性x射线散射(RIXS)的公式，它准确地考虑了价电子和带正电荷的核心空穴之间的吸引，并将该公式应用到空穴掺杂的铜酸盐超导体中。我们重点研究了RIXS线型和能带结构之间的关系，包括对称性的破缺。我们证明了RIXS能够区分竞争序参数，使其成为伪隙相位的有用探测器。
We develop a formalism to study indirect resonant inelastic x-ray scattering (RIXS) in systems with itinerant electrons, accounting for the attraction between valence electrons and the positively-charged core hole exactly, and apply this formalism to the hole-doped cuprate superconductors. We focus on the relationship between RIXS lineshapes and band structure, including broken symmetries. We show that RIXS is capable of distinguishing between competing order parameters, establishing it as a useful probe of the pseudogap phase.
