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…
