Gapless Excitation above a Domain Wall Ground State in a Flat Band Hubbard Model
Makoto Homma, Chigak Itoi
We construct a set of exact ground states with a localized ferromagnetic domain wall and with an extended spiral structure in a deformed flat-band Hubbard model in arbitrary dimens…

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…
