我们从理论上研究了由具有时间延迟的相关光子驱动的分子内部转换的双光子过程。作为一个例子，用莫尔斯振子近似的分子系统来评估过程的效率，根据效率如何随振动态的非绝热耦合率而变化。我们证明了一个有效的双光子过程需要两个不同的相关光子对，它们具有正能量和负能量相关，这取决于非绝热耦合率的值。
We theoretically investigate a two-photon process via molecular internal conversion, driven by correlated photons with time delay. As an example, a molecular system approximated by Morse oscillators is used in order to evaluate the efficiency of the process, in terms of how the efficiency changes with the nonadiabatic coupling rate of vibronic states. We show that an efficient two-photon process requires two different correlated photon pairs with positive and negative energy correlations, depending on the value of the nonadiabatic coupling rate.
