Microstructure of a liquid complex (dusty) plasma under shear

Abstract

The microstructure of a strongly coupled liquid undergoing a shear flow was studied experimentally. The liquid was a shear melted two-dimensional plasma crystal, i.e., a single-layer suspension of micrometer-size particles in a rf discharge plasma. Trajectories of particles were measured using video microscopy. The resulting microstructure was anisotropic, with compressional and extensional axes at around $\pm 45^{\circ }$ to the flow direction. Corresponding ellipticity of the pair correlation function $g(\mathbf{r})$ or static structure factor $S(\mathbf{k})$ gives the (normalized) shear rate of the flow.
