Opis

Anomalous transport is an ever-present phenomenon in astrophysical, geophysical, and laboratory plasmas, and it is a key topic in controlled nuclear fusion research. With the aim of unifying many theoretical models, this is the first book to systematically consider anomalous plasma transport theory. The author discusses a number of plasma instabilities that lead to anomalous transport, emphasizing those aspects attributable to turbulence. Coverage includes the microscopic theory of turbulence, stochastic transport, the method of decorrelation trajectories, and its application to electrostatic turbulence, magnetic turbulence, and zonal flow generation. The text also includes very recent work on nonlocal transport.
