The Horizontal Brazil-Nut Effect — •Kerstin Morber, Christof Kruelle, and Ingo Rehberg — Universität Bayreuth, D-95440 Bayreuth, Germany

The behaviour of spheres rolling on a circularly vibrating table in a circular container is observed. In detail, transport effects in a monolayer consisting of a binary mixture are studied. Depending on the ratio of the particles’ material density and size, migration of the larger particles occurs either towards the boundary or to the center of the circular container. The precise crossing point between both migration effects is determined by varying the intruder’s size and maintaining its material density.
