Self-reverting vortices in chiral active matter [PDF]
Communications PhysicsIn many chiral particle systems, vortex patterns emerge in the velocity fields due to the alignment interactions, but these patterns are non-permanent and decohere quickly.

Collective Behaviors of Active Matter Learning from Natural Taxes Across Scales
Advances in Materials, 2022 Taxis orientation is common in microorganisms, and it provides feasible strategies to operate active colloids as small‐scale robots. Collective taxes involve numerous units that collectively perform taxis motion, whereby the collective cooperation ...

Dynamics of topological defects in the noisy Kuramoto model in two dimensions
Frontiers in Physics, 2022 We consider the two-dimensional (2D) noisy Kuramoto model of synchronization with short-range coupling and a Gaussian distribution of intrinsic frequencies, and investigate its ordering dynamics following a quench. We consider both underdamped (inertial)

Braiding Dynamics in Active Nematics
Frontiers in Physics, 2022 In active matter systems, energy consumed at the small scale by individual agents gives rise to emergent flows at large scales. For 2D active nematic microtubule (ANMT) systems, these flows are largely characterized by the dynamics of mobile defects in ...

Deforming polar active matter in a scalar field gradient [PDF]
New Journal of Physics, 2022 Active matter with local polar or nematic order is subject to the well-known Simha-Ramaswamy instability. It is so far unclear how, despite this instability, biological tissues can undergo robust active anisotropic deformation during animal morphogenesis.

Confined active matter in external fields. [PDF]
Soft Matter, 2022 We analyze a dilute suspension of active particles confined between walls and subjected to fields that can modulate particle speed as well as orientation. Generally, the particle distribution is different in the bulk compared to near the walls.

Porous Media Microstructure Determines the Diffusion of Active Matter: Experiments and Simulations
Frontiers of Physics, 2022 Active swimmers are known to accumulate along external boundaries owing to their persistent self-motion, resulting in a significant reduction in their effective mobility through heterogeneous and tortuous materials.

Dry Aligning Dilute Active Matter
Annual Review of Condensed Matter Physics, 2020 Active matter physics is about systems in which energy is dissipated at some local level to produce work. This is a generic situation, particularly in the living world but not only.

Journal of Physics A: Mathematical and Theoretical, 2022 The presence and significance of active topological defects is increasingly realised in diverse biological and biomimetic systems. We introduce a continuum model of polar active matter, based on conservation laws and symmetry arguments, that ...

Macroscopic, artificial active matter
National Science OpenArtificial active matters on a macroscopic scale, including vibrating particles, robots, and camphor boats, have attracted increasing attentions due to their uniform properties, rich and easily controllable parameters, convenient observation, and the ...
