我们调查多发色团的能量转移允许浴引起的波动在不同的网站相关。作为一个原型系统，我们考虑了一个光捕获天线周围的反应中心。我们表明，量子相干性和相关涨落之间的相互作用可以产生一个室温转移过程，其特征是显着依赖于初始激子态的对称性和离域度。我们的工作说明了这些量子特性如何支持紧密排列的天然和人工捕光复合物中能量转移效率的微调。
We investigate multichromophoric energy transfer allowing for bath-induced fluctuations at different sites to be correlated. As a prototype system, we consider a light harvesting antenna surrounding a reaction center We show that the interplay between quantum coherence and correlated fluctuations can generate a room temperature transfer process featuring a marked dependence on the degree of symmetry and delocalization of the initial exciton state. Our work illustrates how these quantum features could support fine-tuning of energy transfer efficiencies in closely packed natural and artificial light-harvesting complexes.
