Abstract

We build infinitely-many non-radial positive solutions to the Schr\"odinger system \begin{equation*} \left\{\begin{aligned} &-\Delta u_1+u_1=u_1^{{\mathfrak p} }-\Lambda u_1^{a_1} u_2^{a_2}\ \hbox{in}\ \mathbb R^N\\ &-\Delta u_2+u_2=u_2^{{\mathfrak p} }-\Lambda u_1^{b_1}u_2^{b_2} \ \hbox{in}\ \mathbb R^N\\ \end{aligned}\right. \end{equation*} with sub-critical p\mathfrak p-growth as Λ+\Lambda \to +\infty. The profile of each component is the sum of several copies of the positive solution to ΔU+U=Up-\Delta U+U=U^{{\mathfrak p} } in RN\mathbb R^N, centered at suitable {\em peaks} whose mutual distances diverge as Λ\Lambda increases. More precisely, given two concentric regular polygons with kk sides and very large radii, the peaks of the first component are arranged along the edges of the {\em outer} polygon, alternated with those of the second component, and along the kk rays joining the vertices of the two polygons. To the best of our knowledge, this provides the first example of non-radial positive solutions for strongly competitive Schr\"odinger systems in the whole space.
