Symmetry analysis shows orbital hybridization vanishes along the BZ diagonal, allowing the gap on alpha/beta pockets to test d_x2-y2 vs d_z2 dominance; experiments and RPA favor Hund's rule mechanism with full gap.

DFT study identifies Zr, Hf, Th as efficient electron dopants for La3Ni2O7 that boost t_perp between d_z2 orbitals and may elevate Tc via enhanced J_perp.
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
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.
