Spontaneous symmetry breaking in magnetized dust flows
- IEAP, Christian-Albrechts-Universität, D-24098 Kiel (Germany)
Toroidal dust flows in magnetized anodic plasmas are driven by an azimuthal Hall component of the ion drag. By means of Langmuir probe measurements, it was found that the ion drag has a strong radial gradient. This finding is supported by the rotation velocities obtained by particle tracking analysis. The topology of shear flows is also attributed to the radial gradient of the ion drag. Furthermore, from a critical comparison of particle image velocimetry and particle tracking, a much better agreement between the measured rotation velocity and simulations could be achieved.
