Simulation of Dynamics and Self-assembly of Magnetically Decorated Particles — •Maximilian Neumann, Sibylle Gemming, Oliver G. Schmidt, Daniil Karnaushenko, and Aaron Steinhäußer — TU Chemnitz, Chemnitz, Germany

Self-assembly allows for the aggregation of highly complex structures from simple components. Coupled with the highly tunable properties and susceptibility to external fields of magnetic particles this results in the potential to fashion systems with a plethora of applications. By decorating tubular particles with permanent magnets in specific patterns of up/down configuration we create different species of particles, whose behaviour is governed by a mix of attractive and repulsive interactions between individual magnets. This results in selective assembly between specific species, position and orientation. We show simulations of the interaction and dynamics of these particles with and without the influence of external fields and the surrounding medium.
