Abstract: This study investigates the evolution behavior of quantum wave packets in a one-dimensional nonlinear driven system, aiming to explore the impact of external driving on the evolution of quantum wave packets and seek methods to regulate the quantum tunneling effect of the system through external driving. The research numerically simulates the evolution of quantum wavepackets based on the split-operator method and analyzes the quantum tunneling characteristics. The results indicate that the driving frequency significantly influences the quantum tunneling effect, remarkably enhancing the transfer efficiency between potential wells. The maximum tunneling probability can reach 50 times that of the no-driving scenario. This phenomenon is closely related to the dynamic dispersion of wave packets in phase space caused by the modulation of driving frequency.
