论文摘要
当发射器合奏与电磁场相互作用时，发射器之间会诱导偶极 - 偶极相互作用。这些相互作用的大小和形状由电磁场模式的特定形式完全确定。如果将发射器放置在纳米量波导的附近，例如圆柱纳米纤维，这些模式的复杂功能形式使得对偶极 - 偶极相互作用的分析评估笨拙且成本昂贵。在这项工作中，我们提供了有关如何成功计算这些交互的完整详细说明，概述了可以轻松扩展到其他环境和边界条件的方法。这种确切的评估非常重要，因为由于这种系统中相互作用和耗散的集体特征，对相互作用的任何小修改都可能导致实验可观察物的巨大变化，尤其是随着发射器数量的增加。我们通过计算附近发射器链中的圆柱纳米纤维引导的光引导的传动信号来说明这一点。
When an emitter ensemble interacts with the electromagnetic field, dipole-dipole interactions are induced between the emitters. The magnitude and shape of these interactions are fully determined by the specific form of the electromagnetic field modes. If the emitters are placed in the vicinity of a nanophotonic waveguide, such as a cylindrical nanofiber, the complex functional form of these modes makes the analytical evaluation of the dipole-dipole interaction cumbersome and numerically costly. In this work, we provide a full detailed description of how to successfully calculate these interactions, outlining a method that can be easily extended to other environments and boundary conditions. Such exact evaluation is of importance as, due to the collective character of the interactions and dissipation in this kind of systems, any small modification of the interactions may lead to dramatic changes in experimental observables, particularly as the number of emitters increases. We illustrate this by calculating the transmission signal of the light guided by a cylindrical nanofiber in the presence of a nearby chain of emitters.
