论文摘要
从角度分辨的光发射，扫描隧道光谱和量子振荡数据中提取的低能准粒子分散体的差异很常见，并且长期以来一直困扰着量子物质物理领域。在这里，我们通过比较相关金属SR $ _2 $ RHO $ _4 $的数据直接测试了这三种技术的结果的一致性。使用已建立的方案来解释实验数据，我们发现了费米表面地形和载体有效质量的良好一致性。因此，在包括铜岩在内的其他量子材料中显然没有这种一致的一致性表明，这些材料中的电子状态具有不同的非富特液体。最后，我们讨论了从光发射和准粒子干扰数据中提取载体寿命的潜力和挑战。
Discrepancies in the low-energy quasiparticle dispersion extracted from angle resolved photoemission, scanning tunneling spectroscopy and quantum oscillation data are common and have long haunted the field of quantum matter physics. Here, we directly test the consistency of results from these three techniques by comparing data from the correlated metal Sr$_2$RhO$_4$. 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.
