AI 中文摘要
当在结构化环境中发生散射时，行进的量子光脉冲与局域量子系统的相互作用会呈现非马尔可夫特征。本文通过将散射体相干耦合到一个衰减至马尔可夫库的赝模，构建了一种非马尔可夫输入输出理论，该理论在不改变林德布拉德主方程级联特性的情况下，纳入了结构化环境的记忆效应，其解可给出任意期望模式的输出场量子态。我们将该理论应用于二能级原子的受激辐射，以及高斯脉冲通过腔的传输，观察到散射体中相干性的非马尔可夫复兴会扭曲入射脉冲的单模特性，进而产生多模输出场。
英文摘要
The interaction of a traveling pulse of quantum light with a localized quantum system shows non-Markovian features when scattering takes place in a structured environment. Here, we devise a non-Markovian input-output theory by coherently coupling the scatterer to a pseudomode, which decays into a Markovian reservoir. This incorporates memory effects of a structured environment without altering the cascaded nature of the Lindblad master equation, whose solution provides the quantum state of the output field of any desired mode. We apply our theory to the stimulated emission by a two-level atom, and to transmission of a Gaussian pulse through a cavity. We observe that the non-Markovian revival of coherence in the scatterer distorts the single-mode nature of the incoming pulse, thus resulting in a multimode output field.
