Wave turbulence

Wave turbulence in different media: fluids, plasma, atomic, molecular, and optical systems. After mostly finishing the theory of weak turbulence, we move towards stronger interacting systems, using perturbative methods. Non-trivial results on the interplay between non-equilibrium, nonlinearity and nonlocality can already be obtained in the one-loop approximation. We work to describe strong turbulence by resummation of the series within the large-N approach. One goal is to classify universality classes of turbulence.
