标题： Optimal control of population and coherence in three-level $Λ$ systems

摘要： 最优控制理论在三能级系统中高效种群转移和最大相干态创建中的实现被考虑。 我们证明，用于创建最大拉曼相干态的半-STIRAP（受激拉曼绝热通道）方案是根据最优控制理论得出的最优解。 我们还对几种将最优控制理论应用于完全种群转移和最大相干态创建的实现进行了比较研究。 共轭梯度法、Zhu-Rabitz 方法和 Krotov 方法的性能已被分析。 显示英文摘要

摘要： Optimal control theory implementations for an efficient population transfer and creation of a maximum coherence in three-level system are considered. We demonstrate that the half-STIRAP (stimulated Raman adiabatic passage) scheme for creation of the maximum Raman coherence is the optimal solution according to the optimal control theory. We also present a comparative study of several implementations of optimal control theory applied to the complete population transfer and creation of the maximum coherence. Performance of the conjugate gradient method, the Zhu-Rabitz method and the Krotov method has been analyzed.
