摘要: 为探索外界驱动对量子波包演化的影响,寻找通过外界驱动调控系统量子隧穿效应的方法,基于劈裂算符法数值模拟量子波包的演化,分析了量子隧穿特性.结果表明,驱动频率显著影响量子隧穿效应,显著增强在势阱间的转移效率.最大隧穿概率可达无驱动情形的50倍.上述现象和驱动频率调制导致的波包相空间动态弥散密切相关.

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.

Key words: driven systems, wave packets, tunneling effect, quantum control
