Geometry-Induced Dynamics of Confined Chiral Active Matter

Chiral active matter in external potentials

“…21,22 In the case of interacting systems, chirality is able to suppress the clustering typical of active particles [23][24][25][26] but induces novel phenomena, such as emergent vortices induced by the chirality 27,28 or a global traveling wave in the presence of a chemotactic alignment. 29 Chiral active particles exhibit fascinating phenomena also in the presence of alignment interactions giving rise to pattern formation 30,31 consisting of rotating macro-droplets, 32 chiral self-recognition, 33 dynamical frustration, 34 and chimera states. 35 In addition, chirality appears as a fundamental ingredient to observe the hyperuniform phase 36,37 in active matter as well as emerging odd properties 38,39 for instance in the viscosity, [40][41][42] elasticity, 43 and mobility.…”
