Abstract

Despite the structural resemblance of certain cuprate and nickelate parent compounds there is a striking spread of $T_{c}$ among such transition metal oxide superconductors. We adopt a minimal two-orbital $e_{g}$ model which covers cuprates and nickelate heterostructures in different parametric limits, and analyze its superconducting instabilities. The joint consideration of interactions, doping, fermiology, and in particular the $e_{g}$ orbital splitting allows us to explain the strongly differing pairing propensities in cuprate and nickelate superconductors.
