Mobility Anisotropy Reshapes Self-Propelled Motion
Amir Shee, P. S. Pal
We obtain exact closed-form moments for a harmonically trapped self-propelled particle with anisotropic translational mobility in two dimensions. At high persistence, the mean and…
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…
Controlling inertial active Brownian motion via stochastic resetting
Manish Patel, Amir Shee
Inertia is intrinsic to many living and synthetic active systems, from animals and robotic agents to colloidal swimmers, and it strongly shapes transport. Many such systems employ…
Steering chiral active Brownian motion via stochastic position-orientation resetting
Amir Shee
Guiding active motion is important for targeted delivery, sensing, and search tasks. Many active systems exhibit circular swimming, ubiquitous in chemical, physical, and biological…
Tuning Steady Shear Rheology through Active Dopants
Amir Shee, Ritwik Bandyopadhyay, Haicen Yue
We numerically investigate the steady shear rheology of mixtures of active and passive Brownian particles, with varying fractions of active components. We find that even a small fr…
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…
