Abstract

We study the Schr\"{o}dinger-Poisson type system: \begin{equation*} \left\{ \begin{array}{ll} -\Delta u+\lambda u+\left( \mu _{11}\phi _{u}-\mu _{12}\phi _{v}\right) u=% \frac{1}{2\pi }\int_{0}^{2\pi }\left\vert u+e^{i\theta }v\right\vert ^{p-1}\left( u+e^{i\theta }v\right) d\theta & \text{ in }\mathbb{R}^{3}, \\ -\Delta v+\lambda v+\left( \mu _{22}\phi _{v}-\mu _{12}\phi _{u}\right) v=% \frac{1}{2\pi }\int_{0}^{2\pi }\left\vert v+e^{i\theta }u\right\vert ^{p-1}\left( v+e^{i\theta }u\right) d\theta & \text{ in }\mathbb{R}^{3},% \end{array}% \right. \end{equation*}% where 1<p<31<p<3 with parameters λ,μij>0\lambda ,\mu_{ij}>0. Novel approaches are employed to prove the existence of a positive solution for 1<p<31<p<3 including, particularly, the finding of a ground state solution for 2p<32\leq p<3 using established linear algebra techniques and demonstrating the existence of two distinct positive solutions for 1<p<2.1<p<2. The analysis here, by employing alternative techniques, yields additional and improved results to those obtained in the study of Jin and Seok [Calc. Var. (2023) 62:72].
