Two specific antiferromagnetic exchange channels in bilayer La3Ni2O7 produce a robust s± superconducting state via the gene principle and collaborative Fermi-surface rule.
A d_x2-y2 orbital bilayer t-J model with first-principles parameters unifies experimental Tc controls in La3Ni2O7 via particle-hole asymmetry and J_perp dependence, proposing electron doping to enhance Tc.
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.
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.
The review covers experimental and theoretical progress on superconductivity in Ruddlesden-Popper nickelates, emphasizing ambient-pressure thin-film results in La3Ni2O7.
