Here we present an angle-resolved photoemission spectroscopy (ARPES) study of the trilayer nickelate La 4 Ni 3 O 10 revealing its electronic structure and correlations, finding strong resemblances to the cuprates as well as a few key differences. We find a large hole Fermi surface that closely resembles the Fermi surface of optimally hole-doped cuprates, including its $$d_{x^2-y^2}$$ d x 2 - y 2 orbital character, hole filling level, and strength of electronic correlations. However, in contrast to cuprates, La 4 Ni 3 O 10 has no pseudogap in the $$d_{x^2-y^2}$$ d x 2 - y 2 band, while it has an extra band of principally $$d_{3z^2-r^2}$$ d 3 z 2 - r 2 orbital character, which presents a low temperature energy gap. These aspects drive the nickelate physics, with the differences from the cuprate electronic structure potentially shedding light on the origin of superconductivity in the cuprates.","abstract_license":"CC-BY (publisher license, via OpenAlex)","license":"cc-by","is_open_access":true,"retracted":false,"peer_reviewed":null,"categories":["Physics of Superconductivity and Magnetism"],"details":null,"provenance":"openalex","attribution":"Abstract of \"Fermiology and electron dynamics of trilayer nickelate La4Ni3O10\" by Haoxiang Li, Xiaoqing Zhou, Thomas Nummy et al., https://doi.org/10.1038/s41467-017-00777-0, used under its Creative Commons Attribution license (CC-BY); markup removed, otherwise unmodified.","topics":[{"slug":"nickelates-iron-based","name":"Nickelate & Iron-Based Superconductors","domain_slug":"superconductivity"}],"cited_in_dossiers":[]}
