Emergence of rotating clusters in active Brownian particles with visual perception

We examine the group formation and subsequent dynamics of active particles which are equipped with a visual perception using Langevin dynamics simulations. These particles possess an orientational response to the position of the nearest neighbours which are within a vision cone of these particles. We observe the emergence of rotating clusters when the visual perception of the particles are in the intermediate range. We have found that the persistent motion of these active particles are intimately correlated with the emerging structures by analysing the persistence probability as well as the orientational correlation function. For rotating clusters, the persistent probability is found to be very quickly decaying and orientational correlation function shows oscillatory behaviour.
