Directed swarm assembly due to mixed misaligned perception-dependent motility - Communications Physics
Abstract Biological entities as diverse as birds or bacteria frequently self-assemble to display sophisticated collective dynamical behaviors. To understand and design interactions between the individual entities that originate the different flocking behaviors is one of the current most significant challenges in active matter.
Progressive polymer deformation induced by polar activity and the influence of inertia
Polar activity is shown here to induce a progressive local deformation of linear polymer chains, making a clear distinction between head and tail, while the overall chain conformation gets more compact. This breakdown of self-similarity, provoked by the accumulated tension on the polymer backbone induced by the activity, is shown to occur both in the absence and presence of inertia, although it is stronger in the latter case.
Swirling Due to Misaligned Perception-Dependent Motility
A system of particles with motility variable in terms of a vision-type of perception is investigated by a combination of Langevin dynamics simulations in two-dimensional systems and an analytical approach based on conservation law principles. Persistent swirling with predetermined direction is here induced by differentiating the self-propulsion direction and the perception cone axis.
Clustering of self-thermophilic asymmetric dimers: the relevance of hydrodynamics
Clustering of self-thermophilic asymmetric dimers: the relevance of hydrodynamics† Sergi Roca-Bonet, a Martin Wagnera and Marisol Ripoll *a Abstract Self-thermophilic dimers are characterized by a net phoretic attraction which, in combination with hydrodynamic interactions, results in the formation of crystalline-like aggregates. To distinguish the effect of the different contributions is frequently an important challenge.

Filamentous active matter: Band formation, bending, buckling, and defects
Abstract Motor proteins drive persistent motion and self-organization of cytoskeletal filaments. However, state-of-the-art microscopy techniques and continuum modeling approaches focus on large length and time scales. Here, we perform component-based computer simulations of polar filaments and molecular motors linking microscopic interactions and activity to self-organization and dynamics from the filament level up to the mesoscopic domain level.
