Nematic alignment of self-propelled particles: From particle to macroscopic dynamics
Mathematical Models and Methods in Applied Sciences, 2020 Starting from a particle model describing self-propelled particles interacting through nematic alignment, we derive a macroscopic model for the particle density and mean direction of motion. We first propose a mean-field kinetic model of the particle dynamics.

Rectification of self-propelled particles by symmetric barriers [PDF]
Physical Review E, 2013 The motion of self-propelled particles can be rectified by asymmetric or ratchet-like periodic patterns in space. Here we show that a non-zero average drift can already be induced in a periodic potential with symmetric barriers when the self-propulsion velocity is also symmetric and periodically modulated but phase-shifted against the potential. In the

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 ...

Aggregation Pattern Transitions by Slightly Varying the Attractive/Repulsive Function [PDF]
, 2011 Among collective behaviors of biological swarms and flocks, the attractive/repulsive (A/R) functional links between particles play an important role. By slightly changing the cutoff distance of the A/R function, a drastic transition between two distinct ...

Self-organization in systems of self-propelled particles [PDF]
Physical Review E, 2000 We investigate a discrete model consisting of self-propelled particles that obey simple interaction rules. We show that this model can self-organize and exhibit coherent localized solutions in one- and in two-dimensions.In one-dimension, the self-organized solution is a localized flock of finite extent in which the density abruptly drops to zero at the

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.
