External charge perturbation in a flowing plasma and electrostatic turbulence

Autor: Das, Mridusmita, Bora, Madhurjya P.

In this work, an 1D electrostatic hybrid-Particle-in-Cell-Monte-Carlo-Collision (h-PIC-MCC) code [1, 2] is used to study the response of a plasma to a moving, external, charged perturbation (debris). We show that the so-called pinned solitons can for

Possible existence of chaotic oscillations in ion dynamics in the sheath and pre-sheath regions of a dusty plasma, induced by externally driven dust-charge fluctuation, is presented in this work. In a complex plasma, dust charge fluctuation occurs co
