Abstract

We consider the following system of Schr\"odinger equations \begin{equation*}\left.\begin{cases} -\Delta U + \lambda U = \alpha_0 U^3+ \beta UV^2 -\Delta V + \mu(y) V = \alpha_1 V^3+\beta U^2V \end{cases}\right. \text{in} \quad \mathbb{R}^N, \ N=2, 3,\end{equation*} where λ\lambda, α0\alpha_0, α1>0\alpha_1>0 are positive constants, βR\beta \in \mathbb{R} is the coupling constant, and μ:RNR\mu: \mathbb{R}^N \rightarrow \mathbb{R} is a potential function. Continuing the work of Lin and Peng \cite{lin_peng_2014}, we present a solution of the type where one species has a peak at the origin and the other species has many peaks over a circle, but as seen in the above, coupling terms are nonlinear.
