Passivity-Driven Order-Disorder Transitions in Self-Aligning Active Matter
Weizhen Tang, Amir Shee, Zhangang Han +3
We study dense mixtures of passive and active self-aligning disks with isotropic or anisotropic mobility. We find that the passive fraction controls an order-disorder transition th…
Collective dynamics of densely confined active polar disks with self- and mutual alignment
Weizhen Tang, Yating Zheng, Amir Shee +4
We study the emerging collective states in a simple mechanical model of a dense group of self-propelled polar disks with off-centered rotation, confined within a circular arena. Ea…
Emergent Mesoscale Correlations in Active Solids with Noisy Chiral Dynamics
Amir Shee, Silke Henkes, Cristián Huepe
We present the linear response theory for an elastic solid composed of active Brownian particles with intrinsic individual chirality, deriving both a normal mode formulation and a…
Self-Aligning Polar Active Matter
Paul Baconnier, Olivier Dauchot, Vincent Démery +4
Self-alignment describes the property of a polar active unit to align or anti-align its orientation towards its velocity. In contrast to mutual alignment, where the headings of mul…
Noise-induced quenched disorder in dense active systems
Guozheng Lin, Zhangang Han, Amir Shee +1
We report and characterize the emergence of a noise-induced state of quenched disorder in a generic model describing a dense sheet of active polar disks with non-isotropic rotation…
Emergent Metric-like States of Active Particles with Metric-free Polar Alignment
Yinong Zhao, Cristian Huepe, Pawel Romanczuk
We study a model of self-propelled particles interacting with their nearest neighbors through polar alignment. By exploring its phase space as a function of two nondimensional…
