论文摘要
我们使用最佳控制理论获得与绝热性的快捷方式,这些捷径在三级搅拌系统中最大化人口转移,在给定的有限过程中,并在中间状态下指定的耗散率。我们固定泵的强度和stokes脉冲的强度之和,并将混合角作为唯一控制变量。我们确定了该角度的最佳变化,并揭示了奇异弧在最佳轨迹中的作用,以最大程度地减少耗散的影响。
We use optimal control theory to obtain shortcuts to adiabaticity which maximize population transfer in a three-level STIRAP system, for a given finite duration of the process and specified dissipation rate at the intermediate state. We fix the sum of the intensities of the pump and Stokes pulses and use the mixing angle as the sole control variable. We determine the optimal variation of this angle and reveal the role of singular arc in the optimal trajectory, in order to minimize the effect of dissipation.
