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
The perturbation theory of electromagnetic and weak interactions is considered. A hypothesis is proposed that the neutrino is a "carrier" of nonlocality. It means effectively a nonlocal change of the neutrino free-particle propagator. The charged lepton fields (ele'ctron and muon fields) are conside
