Plasma double layer system leading to chaos, intermittency and flicker noise

Abstract

Electrostatic double layers appear in plasma and semiconductor systems with flow of electric current. The systems display bifurcations, chaos, intermittency and power-law of spectral power density that is 1/f-noise also called flicker noise. Fractal analysis of experimental data recorded in time (time-series analysis) indicates that the plasma dynamic systems are of low dimension. Colored and fractal noise influence on measured data may disqualify that conclusion. A piecewise linear dynamical system is considered to clarify this problem. Bifurcation tree, intermittent chaos and 1/f-noise are revealed by the dynamic system.
