Ferromagnetic Domain Wall Ground States in One-Dimensional Deformed Flat-Band Hubbard Model

Makoto Homma, Chigak Itoi

We construct a set of exact ground states with a localized ferromagnetic domain wall and an extended spiral structure in a quasi-one-dimensional deformed flat-band Hubbard model. I…
