We use optimal control theory to obtain shortcuts to adiabaticity which maximize population transfer in a three-level stimulated Raman adiabatic passage system, for a given finite duration of the process and a 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 of the fields as the sole control variable. We determine the optimal variation of this angle and reveal the role of the singular arc in the optimal trajectory, in order to minimize the effect of dissipation. This article is part of the theme issue 'Shortcuts to adiabaticity: theoretical, experimental and interdisciplinary perspectives'.
我们运用最优控制理论来获取绝热捷径，即在给定的有限过程持续时间和中间态特定耗散率的情况下，使三能级受激拉曼绝热通道系统中的布居转移最大化。我们固定泵浦脉冲和斯托克斯脉冲强度之和，并将场的混合角用作唯一控制变量。我们确定该角度的最优变化，并揭示奇异弧在最优轨迹中的作用，以最小化耗散的影响。本文是主题为“绝热捷径：理论、实验和跨学科视角”这一特刊的一部分。
