We study a simple tight-binding (Hubbard) model for electrons interacting via a short range attractive potential. We show that on a cubic lattice, for a half-filled band the ground state may feature both superconductivity and a charge density wave. We examine the response of such a ground state to a

We have performed an X-ray scattering experiment on the Kondo-lattice compound CeΓ°Ru 1Γx Rh x Γ 2 Si 2 ; which shows an incommensurate spin density wave (IC-SDW) in the Rh-concentration range 0:03oxo0:35: We have discovered charge scattering due to the charge density wave (CDW) with a wave vector 2Q
