摘要:

量子辐射脉冲与局部量子系统的相互作用可以通过具有明显初始填充输入和最终填充输出场模式的级联主方程来描述。通过转换到适当的相互作用图景,我们识别出散射体与初始和最终模式的叠加之间的常规Jaynes-Cummings哈密顿量,其强度由传播脉冲模式振幅给出。该转换还识别出散射体与两个模式正交组合之间的耦合。转换后的主方程对系统动力学提供了重要见解,并允许数值高效求解。

英文摘要:

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.
