Estimating the Hubbard repulsion sufficient for the onset of nearly-flat-band ferromagnetism
Lukasz Andrzejewski, Janusz Jedrzejewski
We consider nearly-flat-band Hubbard models of a ferromagnet, that is the models that are weak perturbations of those flat-band Hubbard models whose ground state is ferromagnetic f…
