Open issues and trends in turbulent transport

To tackle successfully the difficult problem of turbulence and transport in fusion plasmas one requires a multidisciplinary approach which uses advances made in related fields, and to foster support for fusion because of the contributions it has made and will make to the understanding of turbulence. Progress in the theory of fusion plasmas turbulence is also a matter of extending modeling power by new analytical techniques instead of confining the methods to some few classical paradigms. In this article, we will present and discuss some approaches that have been developed in astrophysics, condensed matter physics and field theory and which could be applied to solve some complex issues of plasma turbulence. The point is made for 5 issues: 1) self-organization, flows and plasma dynamics, 2) electromagnetic fluctuations, 3) transport barriers dynamics, 4) non-local transport and the role of meso-scales, and 5) new approaches to statistical analysis of turbulent fluctuations
