Solitonic, Periodic and Quasiperiodic Behaviors of Dust Ion Acoustic Waves in Superthermal Plasmas

摘要: The solitonic, periodic, and quasiperiodic behaviors of dust ion acoustic waves in superthermal plasmas with q-nonextensive electrons are studied using the bifurcation theory planar dynamical systems through direct approach. Using a Galilean transformation, model equations transformed to Hamiltonian system involving electrostatic potential. existence solitary periodic is shown for unperturbed system. Analytical forms these presented depending on physical parameters q μ. effects μ characteristics nonlinear waves. It observed that significantly influence structures. Considering an external perturbation, behavior perturbed studied. seen has wave solutions whereas motion same values q,μ v.
