Chiral active matter
WebNov 8, 2024 · We analyse three paradigmatic systems: chiral active fluids composed of spinning frictional particles that are free to translate, oscillating granular gases and active Brownian rollers. In all of these systems, a single effective temperature generated by activity parameterizes both the equation of state and the emergent Boltzmann statistics. WebJan 12, 2024 · This is surprising, as there is no explicit alignment interaction between chiral active colloids to induce any collective spontaneous flow in the system. 25 25. B. Liebchen and D.

WebJul 31, 2024 · Many biological systems, such as bacterial suspensions and actomyosin networks, form polar liquid crystals. These systems are ‘active’ or far-from-equilibrium, due to local forcing of the solvent by the constituent particles. In many cases the source of activity is chiral; since forcing is internally generated, some sort of ‘torque dipole’ is then …
