Multi-orbital Hubbard model simulations for cuprates and nickelates
报告介绍 报告摘要: Motivated by the recent progress of nickelate superconductors, we explored Hubbard-type multi-orbital models focusing on the superconducting instability, non-Fermi liquid behavior, and charge density wave states. In particular, relevant to Ni-112 superconducting family, we showed that an additional dry metallic band can shift the SC dome of the correlated Hubbard band towards the ...
