Change in collective motion of colloidal particles driven by optical vortex with driving force and spatial confinement

We studied the change in collective behavior of optically driven colloidal particles on a circular path. The particles are simultaneously driven by the orbital angular momentum of an optical vortex beam generated by a holographic optical tweezer. The driving force is controlled by the topological charge / of
