ABSTRACT
Plasma is one of the four fundamental states of matter, being a conductive assembly of charged particles, neutrals, and fields that exhibit collective effects. The study of plasma dynamics focuses on the properties of classical, collective, and many-body systems and finds applications in plasma processing, fusion, intense particle beams, and fluid dynamics. In complex systems, and thus in plasma, deterministic chaos arises in association with the emergence of spatiotemporal structures. Plasma is a nonlinear system very favorable for developing of spatial, temporal, or spatio-temporal structures such as double layers, multiple double layer, solitons. The successive double layers are located precisely at the abrupt changes of luminosity between two adjacent plasma shells. The ion-acoustic instability is very sensitive to the background plasma parameters. All the physical quantities that describe the dynamics will be normalized with respect to the quantities characteristic of the electronic component of plasma.
