Extended fRG calculation of the infinite-U Hubbard model on the square lattice yields a density-driven sequence of paramagnetic Fermi liquid, antiferromagnetic stripe, and Nagaoka ferromagnetic phases, with the ferromagnet displaying an incoherent flat band and two regimes separated by a Lifshitz 2D
