利用分段绝热通道实现布居数从单态到预选叠加态的完全转移

Complete transfer of populations from a single state to a pre-selected superposition of states using Piecewise Adiabatic Passage

Evgeny A. Shapiro, Valery Milner, Moshe Shapiro

摘要:

我们开发了一种方法,用于执行强大的和选择性的转移人口之间的一个单一的水平和预先选定的能量本征态的叠加。在频域中,我们的方法相当于执行一系列同时绝热通道到目标叠加态的每个组件。从时域来看,该方法通过在目标波包重新访问Franck Condon区域时累积目标波包的波函数来工作,这相当于分段绝热通道技术的扩展[ Shapiro等人,物理修订版信函99,033002(2007)]的多国制度。通过对Na_2分子的数值试验,验证了该方法的可行性。

英文摘要:

We develop a method for executing robust and selective transfer of populations between a single level and pre-selected superpositions of energy eigenstates. Viewed in the frequency domain, our method amounts to executing a series of simultaneous adiabatic passages into each component of the target superposition state. Viewed in {the} time domain, the method works by accumulating the wavefunction of the target wave packet as it revisits the Franck Condon region, in what amounts to an extension of the Piecewise Adiabatic Passage technique [ Shapiro et.al., Phys. Rev. Lett. 99, 033002 (2007)] to the multi-state regime. The viability of the method is verified by performing numerical tests for the Na_2 molecule.
