Elementary Processes in Complex Plasmas

Abstract

In this chapter, we give the basic description of the main physical processes which create large sinks of plasma by dust grains. We consider first an individual grain embedded in a plasma to study screening, scattering, and absorption of plasma particles. Then we estimate the effect of many grains on other plasma components; in particular, the rate of damping and the scattering introduced by the presence of grains. These are the elementary processes of the creation of plasma fluxes in complex plasmas. These fluxes also inevitably change the ground state of the dust-plasma system, the mode propagation and the grain interactions, which are the subjects of consideration in subsequent chapters.KeywordsDust ParticleElementary ProcessDrift VelocityCharge ProcessDust ChargeThese keywords were added by machine and not by the authors.
