Abstract
We report on the diffusive motion of dielectric testing particles floa ting in a turbulent nematic fluid under the effect of an external osci llating electric field. The particle is viewed as a tracer of the unde rlying turbulence. We calculate the diffusion coefficients and the pro bability distribution of the particle displacements, thus showing that the motion of the particle is a classical Brownian diffusion.
