The second video (Visualization 1) shows how changing the sign of change the rotation direction of the potential pattern. This can be seen in Eq. (13) that the handedness of rotation, clockwise or counterclockwise, depends on the sign of . In other words, the rotation and the moving direction of the trapped particle along the spiral trajectories can be altered by properly controlling the phase of the beams.
