论文摘要
使用电偶极子来描述两个实体之间的光结合相互作用是物理，化学和材料科学的常规近似。但是，当实体的大小与电磁场的空间范围或两个实体之间的距离相当时，材料结构的缺乏使得近似不足。在这项研究中，我们基于宏观量子电动力学理论框架中的过渡电流密度发展了辐射和非辐射共振能量转移的统一理论。所提出的理论使我们能够描述两个在空间依赖的真空电场中具有任意材料结构的实体之间的极化辅助共振能量转移。为了证明所提出的理论的普遍性，我们严格地证明我们的理论可以涵盖过渡密度立方体方法的主要结果和等离子耦合的共振能传递。我们认为，这项研究为探索电偶极子范围之外的光 - 物质相互作用提供了一个有希望的方向，并为材料物理学提供了新的见解。
Using electric dipoles to describe light-matter interactions between two entities is a conventional approximation in physics, chemistry, and material sciences. However, the lack of material structures makes the approximation inadequate when the size of an entity is comparable to the spatial extent of electromagnetic fields or the distance between two entities. In this study, we develop a unified theory of radiative and non-radiative resonance energy transfer based on transition current density in a theoretical framework of macroscopic quantum electrodynamics. The proposed theory allows us to describe polariton-assisted resonance energy transfer between two entities with arbitrary material structures in spatially dependent vacuum electric fields. To demonstrate the generality of the proposed theory, we rigorously prove that our theory can cover the main results of the transition density cube method and the plasmon-coupled resonance energy transfer. We believe that this study opens a promising direction for exploring light-matter interactions beyond the scope of electric dipoles and provides new insights into material physics.
