两个简并靶态间布居转移分支比的完全量子控制
Complete quantum control of the population transfer branching ratio between two degenerate target states
摘要：
提出了一种五能级四脉冲相敏扩展受激拉曼绝热通过方案，实现了对两个简并靶态之间布居转移分支比的完全控制。控制是通过一个三节点零本征态，可以与任意叠加的目标状态。我们的研究结果表明，完全抑制两个简并产物状态之一的产率，因此在光化学中的绝对选择性，是可以实现的和可预测的，即使没有事先研究不需要的产物状态的属性。
英文摘要：
A five-level four-pulse phase-sensitive extended stimulated Raman adiabatic passage scheme is proposed to realize complete control of the population transfer branching ratio between two degenerate target states. The control is achieved via a three-node null eigenstate that can be correlated with an arbitrary superposition of the target states. Our results suggest that complete suppression of the yield of one of two degenerate product states, and therefore absolute selectivity in photochemistry, is achievable and predictable, even without studying the properties of the unwanted product state beforehand.
