论文摘要
了解嵌入在工程骨骼环境中的局部量子系统的动力学是量子光学和开放量子系统理论的核心问题。我们提出了一种形式主义，用于研究来自局部量子系统的几个粒子散射，该量子系统与通过不均匀的波平等描述的骨浴相互作用。特别是，我们提供了这种相互作用系统的量子散射矩阵与不均匀波平等的频域解之间的确切关系，从而提供了访问散射的几个粒子波式零件波式的空间分布的访问。本文开发的形式主义为计算铺平了理解结构化培养基对嵌入其中局部量子系统散射特性的影响的方法，而无需简化对结构化培养基物理学的假设。
Understanding dynamics of localized quantum systems embedded in engineered bosonic environments is a central problem in quantum optics and open quantum system theory. We present a formalism for studying few-particle scattering from a localized quantum system interacting with an bosonic bath described by an inhomogeneous wave-equation. In particular, we provide exact relationships between the quantum scattering matrix of this interacting system and frequency domain solutions of the inhomogeneous wave-equation thus providing access to the spatial distribution of the scattered few-particle wave-packet. The formalism developed in this paper paves the way to computationally understanding the impact of structured media on the scattering properties of localized quantum systems embedded in them without simplifying assumptions on the physics of the structured media.
