Global dynamics below the ground states for NLS under partial harmonic confinement


Abstract in English

We are concerned with the global behavior of the solutions of the focusing mass supercritical nonlinear Schr{o}dinger equation under partial harmonic confinement. We establish a necessary and sufficient condition on the initial data below the ground states to determine the global behavior (blow-up/scattering) of the solution. Our proof of scattering is based on the varia-tional characterization of the ground states, localized virial estimates, linear profile decomposition and nonlinear profiles.
