Evolution of Nagaoka phase with kinetic energy frustrating hopping

We investigate, using the density-matrix renormalization group, the evolution of the Nagaoka state with t′ hopping that frustrates the hole kinetic energy in the U=∞ Hubbard model on the square and anisotropic triangular lattices. We find that the Nagaoka ferromagnet survives up to a rather small t&...
