Lane formation in a two dimensional system with Lennard-Jones like interactions — •Christopher Wächtler, Florian Kogler, and Sabine H. L. Klapp — Institut für Theoretische Physik, Technische Universität Berlin, Hardenbergstr. 36, 10623 Berlin, Germany

Using Brownian Dynamics simulations we investigate a prototype model system undergoing lane formation. The latter is a non-equilibrium transition in binary mixtures of oppositely driven particle species. In contrast to previous studies of repulsively interacting particles, which form perfect lanes only at infinitely large driving forces [1], we here examine this transition in a system involving attractive Lennard-Jones like interactions. We present new findings on how parameters such as system size, driving force and interaction strength influence lane formation in this system.
