Position-dependent STM spectra in La2PrNi2O7 are computed from a two-orbital bilayer model, showing orbital-selective coherence peaks and impurity scattering that enable band identification.
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.
Multiband effects and orbital-selective damping in bilayer nickelates produce pronounced temperature dependence in the Hall coefficient via the quasi-quantum metric contribution to transport.
The review covers experimental and theoretical progress on superconductivity in Ruddlesden-Popper nickelates, emphasizing ambient-pressure thin-film results in La3Ni2O7.
