Abstract
We study strong instability of standing waves eiωtφω(x) for nonlinear Schrödinger equations with L2-supercritical nonlinearity and a harmonic potential, where φω is a ground state of the corresponding stationary problem. We prove that eiωtφω(x) is strongly unstable if ∂λ2E(φωλ)|λ=1 ≤ 0, where E is the energy and vλ(x) = λN/2v(λx) is the L2-invariant scaling.
