Density-mediated spin correlations drive edge-to-bulk flow transition in active chiral matter

AP Petroff, C Whittington, A Kudrolli - Physical Review E, 2023 - APS
We demonstrate that edge currents develop in active chiral matter due to boundary shielding
over a wide range of densities corresponding to a gas, fluid, and crystal. The system is …

Colloids with perception-dependent motility: Dynamics and structure of rotating aggregates and directed swarms

R Saavedra - 2023 - kups.ub.uni-koeln.de
In this thesis we focus on two-dimensional systems of colloids governed by Brownian
dynamics that are able to sense their neighbors via a visual-type of perception, then they …
