Abstract
In this work, we study bidisperse mixtures of self-propelled magnetic particles of different shapes via discrete element method simulations. We show how these particles self-assemble into clusters and how these clusters depend on the ratio of the mixture, the magnetic interaction, and the shape of the grains. It is found that the mix ratio of the system controls the cluster size. Besides, the intensity of the magnetic dipoles and the shape of the grains in the mixture rule the average number of neighbors in contact and the shape of the clusters. By varying the intensity of the interactions, globular, linear and branched clusters were obtained.
Highlights
In this work, we study bidisperse mixtures of self-propelled magnetic particles of different shapes via discrete element method simulations
By varying the ratio between them, we vary the forces intensity. Tions of these ideas have been extended to active granular matter [7, 8]
We analyze the final configuration after a long period of time of each simulated system using tools from network theory when varying particle types, mix ratio and interaction intensities
Summary
We study bidisperse mixtures of self-propelled magnetic particles of different shapes via discrete element method simulations. 2.2 Interaction forces and system dimensions ent patterns or clusters of different shapes and sizes [9, 10]. We present 2D discrete element simulations of magnetic disks and triangles.
