Binary Mixtures of Active and Passive Particles — •Francesco Alaimo1,2 and Axel Voigt1,2,3 — 1Institut für Wissenschaftliches Rechnen, TU Dresden, Dresden, Germany — 2Dresden Center for Computational Materials Science (DCMS), TU Dresden, Dresden, Germany — 3Center for Systems Biology Dresden (CSBD), Dresden, Germany
We use a modification of the Binary Phase Field Crystal model to introduce a continuous approach for binary mixtures of passive and active particles.
This continuous model is used to numerically study different effects that arise in binary mixtures. First, we see how activity promotes crystallization and cluster formation in a passive system, a phenomenon that has been observed experimentally. By varying the relative densities we can observe how passive obstacles influence the dynamics of active particles. Finally, we show how, under specific conditions, a crowded environment can lead to a partial trapping of active particles.
