Resumen

In this paper, we study the induced torque characteristics in Landau-quantized graphene systems under the influence of optical vortex fields. Through numerical simulations and analysis, we investigate the impact of various system parameters, including the decay rate, detuning, coupling field strength, and initial probability amplitudes, on the magnitude and behavior of the induced torque. Our results reveal intriguing insights into the interplay between system parameters and the resulting torque behaviors. Specifically, we observe that the magnitude of induced torque can be finely controlled and even enhanced by judiciously adjusting these parameters. Notably, we find that the detuning parameter plays a crucial role in shaping the resonant response of the system, while the coupling field strength and initial probability amplitudes significantly influence the torque magnitude. The results highlight the potential for precise manipulation and optimization of torque generation in graphene-based systems for a range of applications, including nanomechanical systems and optoelectronics.
