DYNAMICAL BEHAVIORS OF COULOMB CRYSTALS AND LIQUIDS IN STRONGLY COUPLED DUSTY PLASMAS(Session II : Chaos, The 1st Tohwa University International Meeting on Statistical Physics Theories, Experiments and Computer Simulations)

Abstract

We experimentally study the microscopic dynamical behaviors of the strongly coupled dusty plasma with SiO_2 suspensions in low pressure rf Ar discharge through optically tracing the trajectories of particles. As rf power increases, the large scale cooperative domain motion and rotation, cyclic hopping, defect motion and interaction, and diffusive type motion are excited and observed.
