Title: On the relation between secondary and modulational instabilities

Abstract

The nonlinear saturation of microinstabilities in toroidal magnetoplasmas is sometimes discussed in the framework of secondary instability theory. At the same time, it has been proposed that the nonlinear generation of zonal flows--which are often responsible for turbulence control--can be explained in terms of modulational instabilities. The question of how these two approaches are connected to each other is addressed.
