【 摘 要 】

We generalize the model of Hatsugai and Kohmoto and find ground states which do not show the properties of Fermi liquids. We work in two space dimensions, but it is straightforward to generalize to higher dimensions. The ground stale is highly degenerate and then is no discontinuity in the momentum distribution: i.e., there is no Fermi, surface. The Green's function generically has a branch cut.
