The recent and exciting discovery of superconductivity in the hole-doped infinite-layer nickelate Nd_1-$$δ$$Sr_$$δ$$NiO₂ draws strong attention to correlated quantum materials. From a theoretical viewpoint, this class of unconventional superconducting materials provides an opportunity to unveil a physics hidden in correlated quantum materials. Here we study the temperature and doping dependence of the local spectrum as well as the charge, spin and orbital susceptibilities from first principles. By using ab initio LQSGW+DMFT methodology, we show that onsite Hund’s coupling in Ni-$$d$$ orbitals gives rise to multiple signatures of Hund’s metallic phase in Ni-e_$$g$$ orbitals. The proposed picture of the nickelates as an e_$$g$$ (two orbital) Hund’s metal differs from the picture of the Fe-based superconductors as a five orbital Hund’s metal as well as the picture of the cuprates as doped charge transfer insulators. Our finding uncovers a new class of the Hund’s metals and has potential implications for the broad range of correlated two orbital systems away from half-filling.
