论文摘要
在等离激性手性中，已经研究了金属纳米颗粒（NP）和手性分子之间的库仑相互作用引起的圆二色性现象。同时，在共振条件下，由于强耦合，染料分子和金属NP会产生巨大的狂犬分裂。如果手性分子处于等离子体的共振，那么引入了等离子体与分子之间的强烈相互作用会发生什么？在本文中，我们研究了一个球形核壳模型，并在圆形偏振光（CPL）的激发下分析了其光谱现象。基于NPS和手性分子之间的库仑相互作用，我们将展示各种因素如何影响强耦合。我们已经获得了血浆与手性分子之间相互作用的三种机制：强耦合（RABI分裂至243mev），增强的吸收和诱导的透明度。 CPL和手性分子与CPL相反手性的相互作用比相同的手性强的手性更强，并且两个峰的线宽度比相同的手性的线宽度更接近，这表明，对于rabi裂，用chirality进行了chir，相互作用的机制更深。该结果将有助于进一步研究等离子体与手性分子之间的相互作用。
In plasmonic chirality, the phenomenon of circular dichroism for achiral nanoparitcles caused by Coulomb interaction between metal nanoparticles (NPs) and chiral molecules have been studied. At the same time, under the resonance condition, the dye molecules and metal NPs will produce huge Rabi splitting due to strong coupling. If the chiral molecules are at the resonance of the plasmon, what will happen for the strong interaction between the plasmon and molecules with chirality introduced? In this paper, we investigate a spherical core-shell model and analyze its spectral phenomena under the excitation of circularly polarized light (CPL). Based on Coulomb interaction between NPs and chiral molecules, we will show how the various factors affect the strong coupling. We have obtained three mechanisms for the interaction between plasmons and chiral molecules: strong coupling (Rabi splitting up to 243mev), enhanced absorption and induced transparency. The interaction between CPL and chiral molecules with the opposite chirality to CPL is stronger than that of the same chirality, and the line width of the two peaks is closer than that of the same chirality, which shows that for the Rabi splitting with chirality, there are deeper mechanisms for the interaction. This result will be helpful for further research on the interaction between plasmon and molecules with chirality.
