Two specific antiferromagnetic exchange channels in bilayer La3Ni2O7 produce a robust s± superconducting state via the gene principle and collaborative Fermi-surface rule.
Raman response calculations for multiorbital nickelate models produce distinct spectral signatures for different superconducting pairing symmetries.
Constrained-path QMC simulations of a bilayer Hubbard model map a crossover from d-wave to s±-wave pairing driven by Hund's coupling and crystal field splitting in La3Ni2O7.
DFT-based tight-binding models and FRG calculations predict that reducing in-plane lattice constant or increasing out-of-plane constant in La3Ni2O7 films increases Fermi-level DOS and enhances Tc while preserving s± pairing.
