论文摘要
从理论上讲，我们提出了一种双孔纠缠增强的多维光谱技术，作为超快策略中耗散偏振动力学的探针。它应用于代表原型多站点激子量子骨料的腔体单体光合复合物。该提出的技术被证明对两者和单启示子空间之间的势间极性相干性特别敏感。事实证明，它能够监测腔体介导的激子相关性的动力学作用，并在存在语音子诱导的耗散的情况下进行逐渐变化。证明纠缠两光源的非古典性可增强信号的超快速和宽带相关特征，从而指示导致远程腔体辅助激子迁移的潜在状态相关性。
We theoretically propose a biphoton entanglement-enhanced multidimensional spectroscopic technique as a probe for the dissipative polariton dynamics in the ultrafast regime. It is applied to the cavity-confined monomeric photosynthetic complex that represents a prototypical multi-site excitonic quantum aggregate. The proposed technique is shown to be particularly sensitive to inter-manifold polariton coherence between the two and one-excitation subspaces. It is demonstrated to be able to monitor the dynamical role of cavity-mediated excitonic correlations, and dephasing in the presence of phonon-induced dissipation. The non-classicality of the entangled biphoton sources is shown to enhance the ultra-fast and broadband correlation features of the signal, giving an indication about the underlying state correlations responsible for long-range cavity-assisted exciton migration.
