Brownian motion of a self-propelled particle [PDF]
Journal of Physics: Condensed Matter, 2011 Overdamped Brownian motion of a self-propelled particle is studied by solving the Langevin equation analytically. On top of translational and rotational diffusion, in the context of the presented model, the "active" particle is driven along its internal orientation axis.

Forces that control self-organization of chemically-propelled Janus tori
Communications Physics, 2022 The presence of a constraining environment exerts an influence on the behavior of self-propelled synthetic microswimmers, challenging the prediction and control of their individual and collective behaviour in realistic situations.

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

Fluctuations and pattern formation in self-propelled particles [PDF]
Physical Review E, 2010 We consider a coarse-grained description of a system of self-propelled particles given by hydrodynamic equations for the density and polarization fields. We find that the ordered moving or flocking state of the system is unstable to spatial fluctuations beyond a threshold set by the self-propulsion velocity of the individual units.

Collective behavior of penetrable self-propelled rods in two dimensions [PDF]
, 2013 Collective behavior of self-propelled particles is observed on a microscale for swimmers such as sperm and bacteria as well as for protein filaments in motility assays.

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

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.

Cavitation Inception on Microparticles: A Self-Propelled Particle Accelerator [PDF]
Physical Review Letters, 2004 Corrugated, hydrophilic particles with diameters between 30 and 150 microm are found to cause cavitation inception at their surfaces when they are exposed to a short, intensive tensile stress wave. The growing cavity accelerates the particle into translatory motion until the tensile stress decreases, and subsequently the particle separates from the ...
