Flocking from a quantum analogy: spin–orbit coupling in an active fluid
New Journal of Physics, 2018 Systems composed of strongly interacting self-propelled particles can form a spontaneously flowing polar active fluid. The study of the connection between the microscopic dynamics of a single such particle and the macroscopic dynamics of the fluid can ...

Passive Janus particles are self-propelled in active nematics
New Journal of Physics, 2022 While active systems possess notable potential to form the foundation of new classes of autonomous materials (Zhang et al 2021 Nat. Rev. Mater. 6 437), designing systems that can extract functional work from active surroundings has proven challenging. In

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.

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 ...

Dynamics of self-propelled particles passing a bottleneck
New Journal of Physics, 2020 We study the passage of active and passive granular particles through a bottleneck under gravitational bias. The grains are pharmaceutical capsules with spherocylindrical shapes on a vibrating table. The vibrating ground plate is slightly tilted in order

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

Long-ranged velocity correlations in dense systems of self-propelled particles
, 2021 Model systems of self-propelled particles reproduce many phenomena observed in laboratory active matter systems that defy our thermal equilibrium-based intuition.
