Fluctuations in dusty plasmas

U de Angelis, G Capobianco, C Marmolino, C Castaldo2006年Plasma Physics and Controlled FusionIF 2.2出版社

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.

日本語訳

ダストの電荷および密度のゆらぎは、プラズマの基本的な性質——低周波モードの分散、プラズマのゆらぎ——を大幅に変化させ得るとともに、ダストのゆらぎを無視した場合には見られない新たな効果——負に帯電したダスト粒子間の引力、ダストおよびイオンの確率的加熱——を引き起こし得る。これらの効果を記述するために、ゆらぎの運動論が用いられ、特にダストが存在する非磁化プラズマにおけるプラズマゆらぎのスペクトル密度の変化が考察される。
