Video recordings of the experiments.
(a) Repulsive interaction between OV and gold particles. The two particles are the same size but located at different distances from the focal plane. (b) Rotation of a particle in the OV field. White-dashed circle in (a,b) indicates the rotation radius of the particle. (c) The particles are captured and rotated by PV. The arrows denote motion direction of particles and the white circle represents the PV main-lobe donut. Diameter of gold particles is about 1 μm, the working wavelength is 1064 nm, the topological charge of the OV beam is 5 and the incident power is 100 mW.
