Oscillatory phase separation in active particle systems — •Andre Förtsch, Lisa Rapp, Fabian Bergmann, and Walter Zimmermann — University of Bayreuth, Bayreuth, Germany

We introduce a model with two types of interacting active particle A and B. We assume A-A attraction, A-B attraction and B-B repulsion. The continuum approximation corresponds to two chemotactically interacting species. This continuum model shows an oscillatory instability. Since the two particle types are conserved, this oscillatory instability leads to oscillatory phase separation. Particle simulations leads to the same scenario. Above the oscillatory onset of phase separation we find traveling clusters in simulations.
