ABSTRACT

In this paper, we study the following nonlinear Schrödinger–Newton system {ΔuV(x)u+Ψu=0,xR3,ΔΨ+12u2=0,xR3,which is a nonlinear system obtained by coupling the linear Schrödinger equation of quantum mechanics with the gravitation law of Newtonian mechanics. Assuming that V(y) is radial and satisfies some algebraic decay at the infinity, we construct infinitely many non-radial positive solutions which have polygonal symmetry with respect to y1 and y2 and are even in y2 for the system above by the Lyapunov-Schmidt reduction method. Moreover, we have overcame some new difficulties caused by the non-local term.
