The cubic Szegö equation is a toy model related to one dimensional nonlinear waves. Using tools from harmonic analysis, we prove that this Hamiltonian evolution enjoys both complete integrability and long time superpolynomial transition to high frequencies. This is a joint work with Sandrine Grellier.
