Existence of solutions for a system of coupled nonlinear Schrödinger equations
This paper proves the existence of positive solutions for a system of two coupled nonlinear stationary Schrödinger equations in R3 under certain conditions on the potential V and nonlinearity h. The solutions decay exponentially near local minima of V and have energy concentrating around these points as epsilon goes to 0. The proof uses a generalized Nehari manifold method that is new for this more general nonlinearity, restricting the prior work to R3.
