dc.description.abstract | Motivated by the recent discovery of superconductivity in infinite-layer nickelates RE1-delta Sr delta NiO2 (RE = Nd, Pr), we study the role of Hund coupling J in a quarter-filled two-orbital Hubbard model, which has been on the periphery of the attention. A region of negative effective Coulomb interaction of this model is revealed to be differentiated from three- and five-orbital models in their typical Hund metal active fillings. We identify distinctive regimes including four different correlated metals, one of which stems from the proximity to a Mott insulator, while the other three, which we call "intermediate" metal, weak Hund metal, and valenceskipping metal, fromthe effect of J being away fromMottness. Defining criteria characterizing these metals is suggested, establishing the existence of Hund metallicity in two-orbital systems. | - |
