Query: Collision-induced torque mediates transition of dynamic patterns formed
  by active particles   It is still challenging to control dynamic self-organization patterns of
self-propelled particles. Although varieties of patterns associated with
chirality have been observed, essential control factors determining patterns
remain unclear. Here, we explore numerically how torque upon particle collision
affects dynamic self-organization. Based on the particle-based model with both
collision-induced torque and torque in self-propulsion, we find that
introducing collision-induced torque turns homogeneous bi-polar orientation
templated by bi-directional alignment into rotating mono-polar flocks.
