Title:

Intermittent and Global Transitions in Plasma Turbulence

Date of publication:

July 2003

Key words:

plasma turbulence, stochastic transitions, statistical approaches, Langevin equation, subcritical excitation, intermittence

Abstract:

The dynamics of the transition processes in plasma turbulence described by the nonlinear Langevin equation (1) is studied. We show that intermittent or global transitions between metastable states can appear. The conditions for the generation of these transitions and their statistical characteristics are determined.
