Diffusion in single layer quasi-magnetized strongly coupled dusty plasmas

Summary form only given. Using the “rotodust” experimental setup [1] at the Hypervelocity Impacts and Dusty Plasmas Lab (HIDPL) of the Center for Astrophysics, Space Physics, and Engineering Research (CASPER) at Baylor University we have realized effective magnetization of single layer dusty plasma systems in the strongly coupled state up to thousands of Teslas of magnetic induction. The self-diffusion in these ensembles of 300 to 400 particles was derived by measuring the cage correlation function [2] in the central region and utilizing the recently found connection between the variation of particle environments (cages) and the diffusion coefficient [3]. Systems parameters (Γ coupling and κ screening in the Yukawa OCP model) were determined using the pair distribution and the velocity autocorrelation functions [4]. The experimental values show good agreement with molecular dynamics simulations.
