On a class of nonlinear Schrödinger-Poisson systems involving a nonradial charge density

Bound state nodal solutions for the non-autonomous Schrödinger–Poisson system in R3

“…In recent years, there has been much attention to SP systems like system (SP λ ) on the existence of positive solutions, ground states, radial solutions and semiclassical states. We refer the reader to [3,4,12,13,14,21,28,29,32,34,35,36,40]. More precisely, Ruiz [32] studied the autonomous SP system…”
