A vortex beam of light is used to enhance and control the lateral and rotary light drag effects in three-level graphene quantum dots. In this study, by using a vortex beam, two practical parameters are introduced to control the optical properties of the system and consequently enhance both the lateral and rotary light drag effects. These parameters are the orbital angular momentum and the azimuthal phase of the applied controlling vortex beam. By increasing the orbital angular momentum of the vortex beam, the absorption of the probe field decreases, while the lateral and rotary light drag effects increase. Furthermore, we found that the azimuthal phase of the vortex beam has a substantial impact on the optical properties of the probe field. Thus, it can be utilized as an efficient parameter for enhancing and controlling light drag effects.
