Lattice dependence of saturated ferromagnetism in the Hubbard model
Thoralf Hanisch, Goetz S. Uhrig, Erwin Mueller-Hartmann
We investigate the instability of the saturated ferromagnetic ground state (Nagaoka state) in the Hubbard model on various lattices in dimensions d=2 and d=3. A variational resolve…

Ferromagnetism in the Hubbard model: instability of the Nagaoka state on the triangular, honeycomb and kagome lattices
Thoralf Hanisch, Burkhard Kleine, Afra Ritzl +1
In order to analyse the lattice dependence of ferromagnetism in the two-dimensional Hubbard model we investigate the instability of the fully polarized ferromagnetic ground state (…
