STUDY ON SELF ORGANIZATION AND COLLECTIVE BEHAVIOR IN DUSTY PLASMA

复杂等离子体是其中嵌入了微米尺寸的尘埃颗粒的等离子体。灰尘颗粒带负电且强耦合，而等离子体颗粒则弱耦合。复杂等离子体的集体行为已经通过分析和计算进行了研究。分析研究揭示了偶极矩对离子流中灰尘颗粒的唤醒电势的影响。研究了磁场对灰尘颗粒的影响，并分析了灰尘颗粒和灰尘簇的旋转。模拟揭示了静电场中灰尘颗粒团簇的形成。

A complex plasma is a plasma in which dust particulates of micron size are embedded. Dust particulates are negatively charged and strongly coupled, while plasma particles are weakly coupled. Collective behavior of a complex plasma has been studied analytically as well as computationally. Analytical study revealed the effect of dipole moment on the wake potential of a dust particulate placed in the ion flow. The magnetic field effect on dust particulates has been studied and the rotation of a dust particulate and a dust cluster is analyzed. Simulation revealed the formation of clustering of dust particulates confined in an electrostatic field.
