Transport processes in 2D strongly coupled complex plasmas: Numerical experiments — •Lu-Jing Hou and Alexander Piel — Institut für Experimentelle und Angewandte Physik, Christian-Albrechts Universität, D-24098 Kiel

Transport processes in low-dimensional physical systems are of particular interest because of their significance in fundamental physics, as well as their applications in many emerging low-dimensional systems, such as Carbon nanotube, graphene, colloidal suspensions and strongly coupled dusty plasmas (SCDPs). In particular, 2D SCDP has been generally regarded as a model system to study transport phenomena in these systems at the atomic level, because of its peculiar properties in favor of manipulation, observation and reproduction. We perform here numerical experiments by using Brownian dynamics method to study diffusion, shear flow and heat conduction in 2D SCDPs, as a necessary complement to real experiments and a bridge connecting theories and experiments. Particular attention is paid to factors that are not easily accessible in experiments, such as neutral gas damping effect, finite-size effect or microscopic fluxes of mass, moment and energy. Results are compared with both real experiments and established theories.
