Abstract

We study the existence and multiplicity of solutions of the following nonlinear Schrödinger equation in the presence of magnetic field: {(−iε∇+A(x))2u+V(x)u=(K(x)∗|u|p)|u|p−2u,|u|∈H1(RN) where V:RN→RV:RN→R is the external potential, K:RN→RK:RN→R is the response function and A=(A1,…,AN):RN→RNA=(A1,…,AN):RN→RN is the magnetic vector potential associated to an external magnetic field BB, that is B=curlAB=curlA. Under suitable assumptions on the functions V(x),K(x)V(x),K(x) and A(x)A(x), if the parameter εε is small enough, we can prove the multiplicity of bound states for the equation by variational methods.
