Active Matter under Cyclic Stretch: Modeling Microtubule Alignment and Bundling
Takumi Tagaki, Seiya Nishikawa, Shuji Ishihara
We investigate the behavior of self-propelled particles under cyclic stretching, inspired by the characteristic pattern dynamics observed in microtubule (MT) motility assays subjec…

Attraction-Induced Cluster Fragmentation and Local Alignment in Active Particle Systems
Sota Shimamura, Nen Saito, Shuji Ishihara
We numerically studied active Brownian particles with attractive interactions. Contrary to our intuition, the attractive force between particles disrupts the formation of a single…

Anti-aligning Self-propelled Model of Two Species: Emergence of Self-organized Heterogeneous Aligned and Clustered Order
Takahiro Oki, Tetsuhiro S. Hatakeyama, Seiya Nishikawa +2
Self-propelled particles with anti-aligning interactions generally do not form a polar order. However, in this Letter, we show that when multiple types of such particles coexist an…
