Two-orbital models with interorbital t-J or t-V interactions exhibit incommensurate d_xy pair density wave superconductivity driven by interband pairing, confirmed by RPA and strong-coupling hard-core pair calculations showing period-2 PDW over wide fillings.
Ligand holes on planar and apical oxygen hybridize selectively with Ni d_x2-y2 and d_z2 orbitals in La4Ni3O10, enabling RIXS to show d_x2-y2 dominance in low-energy excitations and a ~50 meV interlayer superexchange from observed bimagnons.
La5Ni3O11 shows layer-selective physics with the single layer near a Mott instability and the bilayer dominating low-energy states, yielding an electronic structure that closely resembles the bilayer La3Ni2O7.
Superconductivity in La3Ni2O7 arises from interlayer Cooper pairs of 3d_x2-y2 electrons driven by effective J_perp from Hund-assisted AFM exchange transfer, while localized 3d_z2 electrons form rung singlets that produce a pseudogap but no condensate.

Superconductivity in bilayer La$_3$Ni$_2$O$_7$: A review focusing on the strong-coupling Hund's rule assisted pairing mechanism
