Infinitely many multi-peaks solutions for a nonlinear Hartree system

Qihan He, Qingfang Wang

In this paper, we study the following nonlinear Hartree system: $- Δ u_{i} + V_{i} (x) u_{i} = μ_{i} ϕ_{u_{i}} u_{i} + \sum_{j \neq = i} β_{ij} ϕ_{u_{j}} u_{i}$ for $x \in R^{3}$ , with $u_i\in H^1(\math…

Infinitely many new solutions for a nonlinear coupled Schrödinger system

Qingfang Wang, Mingxue Zhai

We revisit the following nonlinear Schrödinger system \begin{align*}\begin{cases} -ε^{2}Δu +P(x) u= μ_1 u^3 +βuv^2, &~\text{in}\;\mathbb {R}^3,\\ -ε^{2}Δv+Q(x) v= μ_2 v^3 +βu^2v, &…
