Generalized spin density wave state of the Hubbard model on the C12 and C60 clusters

L. Bergomi, J. P. Blaizot, Th. Jolicoeur +1

The one-band Hubbard model at half-filling on a truncated tetrahedron (C${}_{12}$), and on the C${}_{60}$ molecule is studied. Within the Hartree-Fock approximation, we find a magnetic…
