Model Construction and a Possibility of Cupratelike Pairing in a New d^{9} Nickelate Superconductor (Nd,Sr)NiO_{2}.

Effective models are constructed for a newly discovered superconductor (Nd,Sr)NiO_{2}, which has been considered as a possible nickelate analog of the cuprates. Estimation of the effective interaction, which turns out to require a multiorbital model that takes account of all the orbitals involved on... View More
