Vortex Structures in Complex Plasmas

Presenter: Alex Samarian

Keywords: Vortex, Distribution, Spatial, Charge, Vorticity, Poisson

Descriptions: Our model was shown to be capable of modeling vortex structures in complex plasmas. Vortex generation requires gradient of dust charge. Vortex characteristics are independent of charge magnitude, which is determined by charge gradient. Experimental support for the simulated vortices are given for general angular velocity distribution, variation of angular frequency with frictional frequency, and the dependence of angular frequency on pin electrode potential.
