Discrepancies in the low-energy quasiparticle dispersion extracted from angle-resolved photoemission, scanning tunneling spectroscopy, and quantum oscillation data are common and have long haunted the field of quantum matter physics. Here, we directly test the consistency of results from these three techniques by comparing data from the correlated metal Sr₂RhO₄. Using established schemes for the interpretation of the experimental data, we find good agreement for the Fermi surface topography and carrier effective masses. Hence, the apparent absence of such an agreement in other quantum materials, including the cuprates, suggests that the electronic states in these materials are of different, non-Fermi liquid-like nature. Finally, we discuss the potential and challenges in extracting carrier lifetimes from photoemission and quasiparticle interference data.

从角分辨光发射，扫描隧道光谱和量子振荡数据中提取的低能准粒子色散的差异很普遍，并且长期困扰着量子物质物理学领域。在这里，我们通过比较相关金属Sr ₂ RhO _4的数据直接测试这三种技术的结果的一致性。。使用已建立的方案来解释实验数据，我们发现费米表面形貌和载体有效质量之间的一致性很好。因此，在其他量子材料（包括铜酸盐）中显然没有这样的协议，表明这些材料中的电子态具有不同的非费米液体状性质。最后，我们讨论了从光发射和准粒子干扰数据中提取载流子寿命的潜力和挑战。
