Abstract
In this paper, we study the following coupled nonlinear Schrödinger system with potentials
where \(z=(u,v):\mathbb {R}^{N}\rightarrow \mathbb {R}^{2}\), \(N\ge 3\), and \(\epsilon \) is a small positive parameter. We assume that the potentials V, W, and nonlinearity f are continuous but are not necessarily of class \(C^{1}\). Combining this with other suitable conditions on f, we prove the existence of semiclassical ground state solutions via generalized Nehari manifold method. Moreover, we determine two concrete sets related to the potentials V and W as the concentration positions and we describe the concentration of these ground state solutions as \(\epsilon \rightarrow 0\). The results presented in this paper improve and extend the previous relevant results.
