Visual quorum sensing in chiral suspensions: Hyperuniformity and edge currents.

ABSTRACT: A well-established phenomenon in active matter is motility-induced phase separation. However, biological systems exhibit a much broader range of collective behaviors and functions due to the exchange of information among their components. In this study, we investigate a 2D active suspension where individual particles either become chiral or reverse their chirality when the density of neighboring particles within their visual cone surpasses a certain threshold-an instance of nonreciprocal interaction akin to quorum sensing in biology. By means of numerical simulations, we found that the suspension can transition between different configurations, including randomly uniform states, two-phase separation, and global strongly hyperuniform states by tuning the range and aperture of the particle v
