论文摘要
Fano和Rabi模型在光学中代表了非常常见的效果。在这里，我们研究了表现出FANO和RABI共振的等离子体系统的连贯时间动力学。我们证明这些系统在根本上显示出不同的动态。带有FANO共振的系统最多可以在脉冲激发下进行一次暂时的节拍，而Rabi制度中的系统可能具有任何数量的节拍。值得注意的是，尽管这种系统的固有性具有很强的反矫正性，但类似Fano的系统显示具有非常特征的连贯尾巴的时间动力学。我们预测的连贯的FANO和RABI动力学可以在时间分辨实验中的等离子纳米晶二聚体中观察到。我们的研究表明，这种连贯的时间等化性的血浆包括非平凡和特征的放松行为，并通过进一步的研究为发展提供了一个有趣的方向。
The Fano and Rabi models represent remarkably common effects in optics. Here we study the coherent time dynamics of plasmonic systems exhibiting Fano and Rabi resonances. We demonstrate that these systems show fundamentally different dynamics. A system with a Fano resonance displays at most one temporal beat under pulsed excitation, whereas a system in the Rabi regime may have any number of beats. Remarkably, the Fano-like systems show time dynamics with very characteristic coherent tails despite the strong decoherence that is intrinsic for such systems. The coherent Fano and Rabi dynamics that we predicted can be observed in plasmonic nanocrystal dimers in time-resolved experiments. Our study demonstrates that such coherent temporal plasmonics includes nontrivial and characteristic relaxation behaviors and presents an interesting direction to develop with further research.
