Talk Title: "Computing Plasma Turbulence in Fusion and Beyond"

Abstract:

Turbulence has always been, and remains, one the greatest challenges in computational physics. However, its pivotal role in systems ranging from the laboratory to the edge of the universe makes its study one of great importance as well. New computing power and new software techniques means that the computational study of turbulence has the potential to have a vast practical impact. In this seminar it is shown, using first-principles numerical studies of turbulence, how the temperature gradient, and hence the performance, of fusion reactors could be dramatically increased. New phenomena such as subcritical turbulence are uncovered and shown to exist inside real fusion systems and new spectral methods are unveiled for tackling problems both in turbulence theory and astrophysics.
