This paper is concerned with the nonlinear Dirac–Poisson system− i∑ k= 1 3 α k∂ k u+(V (x)+ a) β u+ ω u− ϕ u= F u (x, u),− Δ ϕ= 4 π| u| 2, in R 3 where V is an external potential and F is a superlinear nonlinearity modeling various types of interactions. Existence and multiplicity of stationary solutions are obtained for the system with periodicity condition via variational methods.
