Orbital-selective d-wave superconductivity arises exclusively from the itinerant orbital in the two-band t-J model, suppressed by local inter-orbital bound states from the quasi-localized orbital.
Correlations in the nickelate drive the gamma band below the Fermi level and shift the dominant superconducting pairing to d_x2-y2 interlayer spin-singlet mediated by antiferromagnetism and Hund's coupling.
Compressive strain and oxygenation in (La,Pr)₃Ni₂O₇₋δ films delocalize Ni 3d_z² and O 2p_z orbitals, suppress long-range spin-density-wave order, and preserve short-range magnons as prerequisites for superconductivity.
ARPES on (La,Pr,Sm)3Ni2O7 films reveals quasi-2D dx2-y2 bands, finite kz dispersion on dz2 bands, and a superconducting gap of ~18 meV with 2Δ/kBTc ~8 on the dz2-derived band.
Varying the Ni-Ni interlayer distance switches La3Ni2O7/LaAlO3 films between C-type and G-type spin density waves, with s± superconductivity emerging in between.
RPA calculations predict strain-tunable superconductivity in 1313-La3Ni2O7 films, with s± pairing emerging under tensile strain when the γ pocket is optimally sized.
A two-component scenario unifies key observations in bilayer nickelate superconductivity, predicting doping-dependent superconducting domes and normal-state behaviors that differ by interlayer coupling strength.
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.
DMRG simulations on a 1D bilayer two-orbital model for La3Ni2O7 show superconducting correlations suppressed near half-filling of the 3d_z2 orbital, indicating its itinerancy favors pairing.
In a three-orbital model of bilayer nickelate, nonlocal correlations produce spin-polaron shadow bands below the Fermi level when the gamma quasiparticle band crosses it, depending on interorbital interaction strength.
The two-step resistive transition in La2PrNi2O7-δ thin films arises from granular superconductivity involving two distinct grain phases coupled by a Josephson junction network.
Compressive strain enhances Jahn-Teller splitting Δ_JT in La3Ni2O7 films as the key microscopic tuning parameter for superconductivity, matching ARPES and Hall data on specific substrates.
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.
Epitaxial strain enables ambient-pressure superconductivity in bilayer nickelate films, facilitating detailed studies of their properties and phase diagrams.
The review covers experimental and theoretical progress on superconductivity in Ruddlesden-Popper nickelates, emphasizing ambient-pressure thin-film results in La3Ni2O7.
