Dynamic cluster approximation QMC calculations for a bilayer two-orbital model (Ni 𝑑_(x^2−y^2 ) and 𝑑_(3𝑧^2−𝑟^2 )) (left) demonstrate that superconductivity in layered nickelates arises from interlayer electron pairs with the largest amplitude in the 𝑑_(3𝑧^2−𝑟^2 ) orbital (right).
Scientific Achievement: Advanced simulations reveal that superconductivity in bilayer nickelates is driven by interlayer electron pairing mediated by interlayer spin fluctuations.
Significance and Impact: Advanced simulations reveal that superconductivity in bilayer nickelates is driven by interlayer electron pairing mediated by interlayer spin fluctuations.
