手性相互作用的概念已经在涉及不同尺度的物体的各种领域中被深入研究，例如，核子、氨基酸和液晶。其中一个关键问题是手征相互作用如何在初始不相关的物体之间诱导同步效应。在这项研究中，我们提出了一个模型的手性选择性同步荧光（超荧光），涉及在一个cross-stacked金属纳米结构的中心的cross-configured量子发射器。发射器通过反复交换辐射光子而在时间上相互发展相关性，辐射光子经历其环境的手征性。我们的数值计算表明，峰值荧光强度强烈依赖于是否手性的发射器和金属匹配，即使本地化的表面等离子体在发射器的位置充分衰减。我们的手性选择性超荧光模型将提供一个替代工具，用于分析同步过程中的手性相互作用。
The concept of chiral interactions has been intensively studied in various fields involving diverse scales of objects, e.g., nucleons, amino acids, and liquid crystals. One of the key problems is how chiral interactions induce synchronization effects among initially uncorrelated objects. In this study, we propose a model of chirality-selective synchronized fluorescence (superfluorescence) that involves spirally configured quantum emitters at the center of a spirally stacked metal nanostructure. The emitters mutually develop the correlation in time by repeatedly exchanging the radiated photons, which experience the chirality of their environment. We numerically show that the peak fluorescent intensity strongly depends on whether or not the chiralities of the emitters and the metals match, even though the localized surface plasmon decays sufficiently at the positions of the emitters. Our model of chirality-selective superfluorescence will provide an alternative tool for analyzing chiral interactions in synchronization processes.
