论文摘要
极性 - 在空腔中形成的杂化光态状态 - 强烈改变了基本物质的特性。在光学或等离子纳米腔中，极化子通过辐射发射的腔衰减，这是可在实验上访问的。由于分子与量化辐射场的相互作用，极性子表现出光诱导的圆锥形相交（LICIS），从而极大地影响了分子极化子的核动力学。我们表明，下极化子的超快速辐射发射受到LICI施加的几何阶段的控制。这一发现提供了对发射过程的洞察力，此外，还允许人们通过增强具有几何相期术语的极性子的出生 - 脑近似近似来计算这些信号。
Polaritons - hybrid light-matter states formed in cavity - strongly change the properties of the underlying matter. In optical or plasmonic nanocavities, polaritons decay by radiative emission of the cavity, which is accessible experimentally. Due to the interaction of a molecule with the quantized radiation field, polaritons exhibit light-induced conical intersections (LICIs) which dramatically influence the nuclear dynamics of molecular polaritons. We show that ultrafast radiative emission from the lower polariton is controlled by the geometric phase imposed by the LICI. This finding provides insight into the process of emission and, furthermore, allows one to compute these signals by augmenting the Born-Oppenheimer approximation for polaritons with a geometric phase term.
