When dispersed in a nematic liquid crystal, colloidal particles can be driven along the local director by the action of an oscillating electric field. This phenomenon, called liquid-crystal-enabled electro-osmosis results mainly from the unbalanced ionic flows coupled to the distortions of the elastic matrix. Individual particles move ballistically along the local director but feature an anomalous diffusive behavior in the perpendicular direction that we tune by changing the temperature-dependent material properties or the nature of the inclusion.
