Abstract

The coherent interaction between localized surface plasmon resonance modes and excitons of a single or a collection of quantum emitters have fueled the development of novel applications in quantum optics and material science. In this work, using first-principles simulations, we analyse the modifications in absorption spectra and electric near-field enhancements in a structure consisting of an aluminum nanotriangle interacting with a varying number of pyridine molecules (placed at the nanotriangle tips) in close proximity. What’s more, we find very interesting spatial variation in induced electron density and electric near-field enhancements with a remarkable dependence on the number of interacting pyridine molecules and the direction of light illumination. Our results may help to improve our understanding of the light-matter interaction at the sub-nanometer scale.
等离子体-分子系统纳米尺度电场热点映射的理论研究
局部表面等离子体共振模式与单个或多个量子发射体的激子之间的相干相互作用推动了量子光学和材料科学中新应用的发展。在这项工作中,使用第一性原理模拟,我们分析了由铝纳米三角形与不同数量的吡啶分子(放置在纳米三角形尖端)相互作用组成的结构中吸收光谱的变化和电场近场增强。此外,我们发现感应电子密度和电近场增强的空间变化非常有趣,与相互作用的吡啶分子的数量和光照方向有很大的关系。我们的结果可能有助于提高我们对亚纳米尺度光-物质相互作用的理解。
