Double layers in strong turbulent plasma with suprathermal electrons

Distributions of plasma with excess numbers of superthermal electrons are common in space environments and double layer (DL) is one of the very important electrostatic nonlinear wave structures ubiquitous in plasma systems. Based on the modified Zakharov equations, the DLs are studied in the strong turbulent plasmas with Kappa distributed electrons. It appears that in the strong turbulence regime, the presence of additional superthermal particles does not make qualitative changes on the DLs behavior, but modify the thicknesses of the DLs.
