Role of particle conservation in self-propelled particle systems [PDF]
, 2013 Actively propelled particles undergoing dissipative collisions are known to develop a state of spatially distributed coherently moving clusters. For densities larger than a characteristic value, clusters grow in time and form a stationary well-ordered

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.

Non-Gaussian statistics for the motion of self-propelled Janus particles: Experiment versus theory [PDF]
, 2013 Spherical Janus particles are one of the most prominent examples for active Brownian objects. Here, we study the diffusiophoretic motion of such microswimmers in experiment and in theory.

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.

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 ...

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

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
