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 ...

Diffusion properties of active particles with directional reversal
New Journal of Physics, 2016 The diffusion properties of self-propelled particles which move at constant speed and, in addition, reverse their direction of motion repeatedly are investigated.

A particle-field approach bridges phase separation and collective motion in active matter
Nature Communications, 2020 Interacting self-propelled particles exhibit phase separation or collective motion depending on particle shape. A unified theory connecting these paradigms represents a major challenge in active matter, which the authors address here by modeling active ...

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.

Phase separation of self-propelled ballistic particles
Physical Review E, 2018 Self-propelled particles phase separate into coexisting dense and dilute regions above a critical density. The statistical nature of their stochastic motion lends itself to various theories that predict the onset of phase separation. However, these theories are ill equipped to describe such behavior when noise become negligible.

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. Active forces are modeled as an Ornstein-Uhlenbeck stochastic process, characterized by a persistence time and an effective temperature, and particles interact via a Lennard-Jones potential ...

Individual and collective dynamics of self-propelled soft particles [PDF]
, 2014 Deformable self-propelled particles provide us with one of the most important nonlinear dissipative systems, which are related, for example, to the motion of microorganisms.

Asynchrony induces polarization in attraction-based models of collective motion [PDF]
Royal Society Open Science, 2019 Animal groups frequently move in a highly organized manner, as represented by flocks of birds and schools of fish. Despite being an everyday occurrence, we do not fully understand how this works.
