Title: Fermiology and electron dynamics of trilayer nickelate La 4Ni 3O 10

Abstract

Layered nickelates have the potential for exotic physics similar to high T C superconducting cuprates as they have similar crystal structures and these transition metals are neighbors in the periodic table. Here we present an angle-resolved photoemission spectroscopy (ARPES) study of the trilayer nickelate La 4Ni 3O 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 x2-y2 orbital character, hole filling level, and strength of electronic correlations. However, in contrast to cuprates, La 4Ni 3O 10 has no pseudogap in the d x2-y2 band, while it has an extra band of principally d 3z2-r2 orbital character, which presents a low temperature energy gap. Furthermore, 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.
