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.
