Direct comparison of ARPES, STM, and quantum oscillation data for band structure determination in Sr2RhO4

Abstract 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 th...
