对光合捕光效率的研究集中在两个因素上：（1）发色团的纠缠，和（2）环境噪声。虽然发色团是具有强相关电子的共轭π键合分子，但先前的模型隐含地处理了这种相关性，而没有数学变量来衡量相关性增强的效率。在这里，我们概括的单电子/激子模型，明确地显示了增强的发色团内的电子相关的能量转移的效率的影响的多电子/激子模型。该模型提供了更详细的洞察发色团内的电子相关性和发色团之间的电子纠缠的相互作用。利用这种相互作用有助于设计新的节能材料，这才刚刚开始出现。
Research into the efficiency of photosynthetic light harvesting has focused on two factors: (1) entanglement of chromophores, and (2) environmental noise. While chromophores are conjugated π-bonding molecules with strongly correlated electrons, previous models have treated this correlation implicitly without a mathematical variable to gauge correlation-enhanced efficiency. Here we generalize the single-electron/exciton models to a multi-electron/exciton model that explicitly shows the effects of enhanced electron correlation within chromophores on the efficiency of energy transfer. The model provides more detailed insight into the interplay of electron correlation within chromophores and electron entanglement between chromophores. Exploiting this interplay is assisting in the design of new energy-efficient materials, which are just beginning to emerge.
