Numerical simulations show repulsive interactions enhance ferromagnetic correlations at high electron densities in the Kagome Hubbard model and extend the strong-correlation region toward half filling, linking smoothly to Nagaoka ferromagnetism.
DMRG calculations on the two-leg Lieb ladder Hubbard model identify a ferrimagnetic insulator at half filling and a narrow superconducting Luther-Emery phase near filling 2/3.
