Query: Crossover from Intermittent to Continuum Dynamics for Locally Driven
  Colloids   We simulate a colloid with charge q_d driven through a disordered assembly of
interacting colloids with charge q and show that, for q_d \approx q, the
velocity-force relation is nonlinear and the velocity fluctuations of the
driven particle are highly intermittent with a 1/f characteristic. When q_d >>
q, the average velocity ddrops, the velocity force relation becomes linear, and
the velocity fluctuations are Gaussian. We discuss the results in terms of a
crossover from strongly intermittent heterogeneous dynamics to continuum
dynamics. We also make several predictions for the transient response in the
different regimes.
