Dust charge and density fluctuations can substantially change basic plasma properties—dispersion of low frequency modes, plasma fluctuations—and introduce new effects—attraction of negatively charged dust particles, dust and ion stochastic heating—which cannot be found if dust fluctuations are neglected. The kinetic theory of fluctuations is used to describe these effects, in particular the changes in the spectral densities of the plasma fluctuations in un-magnetized plasmas in the presence of dust.

Abstract
Dust charge and density fluctuations can substantially change basic plasma properties—dispersion of low frequency modes, plasma fluctuations—and introduce new effects—attraction of negatively charged dust particles, dust and ion stochastic heating—which cannot be found if dust fluctuations are neglected. The kinetic theory of fluctuations is used to describe these effects, in particular the changes in the spectral densities of the plasma fluctuations in un-magnetized plasmas in the presence of dust.File in questo prodotto:
