Experimental Approach for Obtaining a Complex (Dusty) Plasma Fluid

Abstract

An experimental approach is proposed to obtain a complex (dusty) plasma fluid. In contrast to previously employed laser heating of a complex (dusty) plasma crystal, this approach is based on the mode-coupling instability of the crystal and does not require any additional influence. We consider a typical experiment and report results of post-processing, including the Voronoi-cell area distribution and order parameter, justifying a liquid state of the system existing for a long enough time. The results can be useful for studies of phenomena and properties of fluids at different couplings, such as excitation spectra, density-density correlations, diffusion, and relations between them.
