论文摘要
黄-rhys（HR）因子是一种表征电子偶联的无量纲因子，已广泛用于研究各个领域的材料特性。本着同样的精神，我们提出了一个称为偏振hr因子的数量，以定量描述（i）永久偶极子和（ii）偶极体能够诱导的（i）偶联的效果。前者可以看作是极化位移，而后者与电子耦合偏移有关。在宏观量子电动力学的框架内，可以在没有自由参数的情况下评估任意介电环境中的极化HR因子，耦合移位和修饰的光耦合强度，这些参数与先前的实验结果吻合良好。此外，在我们的理论中发展的极化进程表明，较大的极性人力资源因子可能导致光结向耦合，多极构成和非辐射式过渡。我们认为，这项研究提供了一种有用的观点，可以理解和量化培养基的相互作用。
Huang-Rhys (HR) factor, a dimensionless factor that characterizes electron-phonon coupling, has been extensively employed to investigate material properties in various fields. In the same spirit, we present a quantity called polaritonic HR factor to quantitatively describe the effects of (i) light-matter coupling induced by permanent dipoles and (ii) dipole self-energy. The former can be viewed as polaritonic displacements, while the latter is associated with the electronic coupling shift. In the framework of macroscopic quantum electrodynamics, the polaritonic HR factor, coupling shift, and modified light-matter coupling strength in an arbitrary dielectric environment can be evaluated without free parameters, whose magnitudes are in good agreement with the previous experimental results. In addition, polaritonic progression developed in our theory indicates that large polaritonic HR factors can result in light-matter decoupling, multipolariton formation, and non-radiative transition. We believe that this study provides a useful perspective to understand and quantify light-matter interaction in medium.
