论文摘要
量子辐射的传播脉冲与局部量子系统的相互作用可以通过级联的主方程来描述，其最初填充的输入和最终填充的输出场模式[phys [phys。莱特牧师。 123，123604（2019），Arxiv：1902.09833v3]。通过转换为适当的交互作用图片，我们确定了散点器和初始模式和最终模式的叠加之间通常的Jaynes-Cummings Hamiltonian，其强度由行进的脉冲模式振幅给出。转换还标识了散点子与两种模式的正交组合的耦合。转换的主方程提供了对系统动力学的重要见解，并且允许数值有效的解决方案。
The interaction of a propagating pulse of quantum radiation with a localized quantum system can be described by a cascaded master equation with a distinct initially populated input and a finally populated output field mode [Phys. Rev. Lett. 123, 123604 (2019), arXiv:1902.09833v3]. By transformation to an appropriate interaction picture, we identify the usual Jaynes-Cummings Hamiltonian between the scatterer and a superposition of the initial and final mode, with a strength given by the travelling pulse mode amplitude. The transformation also identifies a coupling of the scatterer with an orthogonal combination of the two modes. The transformed master equation offers important insights into the system dynamics and it permits numerically efficient solutions.
