Topic of Research Seminar: Adiabatic Electron Capture in Non-Maxwellian Plasmas

Abstract: In this talk, electron trapping for generalized (r,q), kappa, and Cairns distribution functions, respectively, will be discussed using the approach adopted by Landau and Lifshitz for Maxwellian trapping of electrons. For illustrative purposes, dispersive and dissipative equations for ion-acoustic waves will be shown in the presence of non-Maxwellian trapped electrons in the small amplitude limit. The solutions of the modified dispersive and dissipative nonlinear equations are reported, and a graphical analysis will be presented to show a detailed comparison of non-Maxwellian and Maxwellian trapping.
