Active Brownian ellipsoids in three spatial dimensions — •Sebenzile Tsabedze and Michael te Vrugt — Institut für Physik, Johannes Gutenberg-Universität Mainz, 55128 Mainz, Germany

We investigate ellipsoidal active Brownian particles with alignment interactions in three spatial dimensions that are propelled orthogonal to their symmetry axis. Their propulsion direction makes the particles biaxial, implying that their dynamics is considerably more complex than in the usually considered case of particles being propelled along their symmetry axis. We use Brownian dynamics simulations and assume the particles to interact via a Gay-Berne potential (for the ellipsoidal repulsion) and a Heisenberg potential (for the interaction).
