我们解决了最近提出的具有两个超导圆顶的重费米子化合物的轨道跃迁场景。我们选择的方法是非共振非弹性 X 射线散射 (NIXS),它可以探测电荷密度并可以定量建模。通过考虑所有温度下相同的轨道序列,我们对此类材料的模型系统的 NIXS 结果进行了很好的描述,从而提出了轨道跃迁是否与第二个超导穹顶的形成有关的问题。实验结果与预测之间的差异可能是由于状态的理论描述缺乏准确性。
We address the recently proposed orbital transition scenario in heavy fermion compounds exhibiting two superconducting domes. Our method of choice is nonresonant inelastic x-ray scattering (NIXS) which probes charge densities and can be modeled quantitatively. Our NIXS results of, a model system of this class of materials, are well described by considering the same sequence of orbitals at all temperatures, thus putting into question whether orbital transitions are related to the formation of the second superconducting dome. The discrepancy between experimental findings and prediction could be due to the lack of accuracy in the theoretical description of thestates.
