Description:
Author(s): F. T. Lisandrini, B. Bravo, A. E. Trumper, L. O. Manuel, and C. J. Gazza 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 c … [Phys. Rev. B 95, 195103] Published Tue May 02, 2017
