On asymptotic stability in energy space of ground states for Nonlinear Schrödinger equations

arXiv:0711.4195 · doi:10.1007/s00220-008-0605-3

Abstract

We consider nonlinear Schrödinger equations in dimension 3 or higher. We prove that symmetric finite energy solutions close to orbitally stable ground states converge asymptotically to a sum of a ground state and a dispersive wave assuming the so called Fermi Golden Rule (FGR) hypothesis. We improve the sign condition required in a recent paper by Gang Zhou and I.M.Sigal
