N2 - The discovery of superconductivity in infinite-layer nickelates has added a new family of materials to the fascinating growing class of unconventional superconductors. By incorporating the strongly correlated multiorbital nature of the low-energy electronic degrees of freedom, we compute the leading super-conducting instability from magnetic fluctuations relevant for infinite-layer nickelates. Specifically, by properly including the doping dependence of the Ni dx2-y2 and dz2 orbitals as well as the self-doping band, we uncover a transition from d-wave pairing symmetry to nodal s & PLUSMN; superconductivity, driven by strong fluctuations in the dz2-dominated orbital states. We discuss the properties of the resulting superconducting condensates in light of recent tunneling and penetration depth experiments probing the detailed superconducting gap structure of these materials.
