Abstract: I will discuss a new type of a derivative nonlinear Schrödinger equation, which can be seen as a continuum version of completely integrable CalogeroMoser manybody systems in classical mechanics. The resulting NLS exhibits many intriguing features such as a Lax pair structure on Hardy spaces, L2criticality, and turbulent solutions. In this talk, I will focus on dynamics of multisoliton solutions, which exhibit an unbounded growth of Sobolev norms (turbulence). This is based on joint work with Patrick Gérard (Orsay).
