The nonequilibrium glassy dynamics of self-propelled particles [PDF]
Soft Matter, 2016 We study the glassy dynamics taking place in dense assemblies of athermal active particles that are driven solely by a nonequilibrium self-propulsion mechanism.

Chemotaxis of Cargo-Carrying Self-Propelled Particles [PDF]
Physical Review Letters, 2021 Active particles with their characteristic feature of self-propulsion are regarded as the simplest models for motility in living systems. The accumulation of active particles in low activity regions has led to the general belief that chemotaxis requires additional features and at least a minimal ability to process information and to control motion.

Reaction processes among self-propelled particles [PDF]
Soft Matter, 2019 Herein, we study a system of self-propelled disks that perform run-and-tumble motion and undergo a reaction process.

Ultrafast, Self-Propelled Particles [PDF]
Physics, 2020 New “Marangoni surfers” that whizz along at 10,000 body lengths per second offer new insight into active matter propelled by surface-tension gradients.

Density-independent model of self-propelled particles [PDF]
Physical Review E, 2013 We examine a density-independent modification of the Vicsek model in which a particle interacts with neighbors defined by Delaunay triangulation. To feasibly simulate the model, an algorithm for repairing the triangulation over time was developed. This algorithm may also be applied to any time-varying two-dimensional Delaunay triangulation.

Anticipation Induces Polarized Collective Motion in Attraction Based Models
Northeast Journal of Complex Systems, 2021 Moving animal groups are prime examples of natural complex systems. In most models of such systems each individual updates its heading based on the current positions and headings of its neighbors.

Escape problem for active particles confined to a disk
Physical Review Research, 2020 We study the escape problem for interacting, self-propelled particles confined to a disk, where particles can exit through one open slot on the circumference.

A Review on the Some Issues of Multiphase Flow with Self-Driven Particles
Applied Sciences, 2021 Multiphase flow with self-driven particles is ubiquitous and complex. Exploring the flow properties has both important academic meaning and engineering value.

Circular Motion of Asymmetric Self-Propelling Particles [PDF]
Physical Review Letters, 2013 Micron-sized self-propelled (active) particles can be considered as model systems for characterizing more complex biological organisms like swimming bacteria or motile cells. We produce asymmetric microswimmers by soft lithography and study their circular motion on a substrate and near channel boundaries.

Spontaneously Flowing Crystal of Self-Propelled Particles [PDF]
Physical Review Letters, 2018 We experimentally and numerically study the structure and dynamics of a monodisperse packing of spontaneously aligning self-propelled hard disks. The packings are such that their equilibrium counterparts form perfectly ordered hexagonal structures. Experimentally, we first form a perfect crystal in a hexagonal arena which respects the same crystalline ...
