Chaotic behavior of current-carrying plasmas in external periodic oscillations

N. Ohno; Masayoshi Tanaka; Akio Komori; Yoshinobu Kawai

A set of cascading bifurcations and a chaotic state in the presence of an external periodic oscillation are experimentally investigated in a current-carrying plasma. The measured bifurcation sequence leading to chaos, which is controlled by changing plasma densities and the frequencies of external oscillations, is in qualitative agreement with a theory which describes anharmonic systems in periodic fields.
