The presence of flat bands near the Fermi energy may lead to an increase in electron correlations and result in unconventional states. Here, non-Fermi liquid behavior and anomalous superconductivity, with a nonmonotonic two-dome-like doping dependence, are observed in Sc2Ir4-xSix and attributed to spin-orbit-coupling driven flat bands.
