迪克在1954年率先提出的分子集合的集体光学响应物理学，长期以来一直是理论和实验研究的中心。由于各种重要的应用，例如在能量转换装置中，环境对这种现象的影响也引起了极大的兴趣。在这篇论文中，我们从实验和理论上证明了放置在金属界面附近的分子的集体衰变率的空间调制。我们在一个非常简单的框架中展示了如何根据分子间的相关性来分析协同光学响应，从而导致不同分子的响应之间的干涉和在附近金属边界上诱导的极化，并预测了在分子聚集体之间的激发能传递中类似的集体干涉现象。
The physics of collective optical response of molecular assemblies, pioneered by Dicke in 1954, has long been at the center of theoretical and experimental scrutiny. The influence of the environment on such phenomena is also of great interest due to various important applications in, e.g., energy conversion devices. In this Letter, we demonstrate both experimentally and theoretically the spatial modulations of the collective decay rates of molecules placed in proximity to a metal interface. We show in a very simple framework how the cooperative optical response can be analyzed in terms of intermolecular correlations causing interference between the response of different molecules and the polarization induced on a nearby metallic boundary and predict similar collective interference phenomena in excitation energy transfer between molecular aggregates.
