Binary Mixtures of Active and Passive Particles — •Francesco Alaimo^1,2 and Axel Voigt^1,2,3 — 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.
