Dynamics of ellipsoidal particles in random light fields — Rene Hermann¹, Christoph Zunke¹, •Florian Platten¹, Arjun G. Yodh², and Stefan U. Egelhaaf¹ — ¹Heinrich Heine University Duesseldorf — ²University of Pennsylvania, Philadelphia, USA

Ellipsoidal polystyrene particles are exposed to a random light field applying different laser power, and the particle motions are tracked by video microscopy. From the particle trajectories, mean-squared (angular) displacements are analyzed. Initial and long-time diffusion, as well as transient intermediate sub-diffusive behavior, are observed for the center-of-mass and angular displacements.
