我们研究了基于绝热通道的种群转移过程的特征能面拓扑结构。我们证明了这种拓扑结构是分析人口迁移和预测其最终结果的基本特征。我们重新解释了各种已知的过程，如受激拉曼绝热通道（STIRAP），频率啁啾绝热通道和斯塔克啁啾快速绝热通道（SCRAP）。此外，利用这张图，我们展示了新的相关转移可能性。特别是，我们表明，我们可以通过选择峰值幅度或脉冲序列来选择性地控制将在Lambda或V系统中填充的STIRAP过程中的电平。
We examine the topology of eigenenergy surfaces characterizing the population transfer processes based on adiabatic passage. We show that this topology is the essential feature for the analysis of the population transfers and the prediction of its final result. We reinterpret diverse known processes, such as stimulated Raman adiabatic passage (STIRAP), frequency-chirped adiabatic passage and Stark-chirped rapid adiabatic passage (SCRAP). Moreover, using this picture, we display new related possibilities of transfer. In particular, we show that we can selectively control the level which will be populated in STIRAP process in Lambda or V systems by the choice of the peak amplitudes or the pulse sequence.
