Query: Self-diffusion in two-dimensional quasi-magnetized rotating dusty
  plasmas   The self-diffusion phenomenon in a two-dimensional dusty plasma at extremely
strong (effective) magnetic fields is studied experimentally and by means of
molecular dynamics simulations. In the experiment the high magnetic field is
introduced by rotating the particle cloud and observing the particle
trajectories in a co-rotating frame, which allows reaching effective magnetic
fields up to 3000 Tesla. The experimental results confirm the predictions of
the simulations: (i) super-diffusive behavior is found at intermediate
time-scales and (ii) the dependence of the self-diffusion coefficient on the
magnetic field is well reproduced.
