Flow of active granular particles through a bottleneck — •Tina Hanselka and Ralf Stannarius — Otto-von-Guericke-Universität Magdeburg

We use screws performing a self-propelled motion on a vibrated plate as a simple model to analyze the collective behavior of active matter systems passing through a constriction. For this we employ a slight tilt of the plate to simulate an effective gravity and to give the particles a preferred direction towards the bottleneck, and we examine the characteristics of flow and clogging as a function of geometrical and driving parameters.
