摘要

為了理解在光合系統中複雜激子的能量傳輸行為，建立一個粗粒化模型是必要的。在本次工作中，我們開發了一個系統化的方法。藉由最小分割法來建構光合系統的粗粒化模型。我們使用這個方法處理三種不同的光合作用網路並且這些粗粒化模型可以很好的還原激子能量傳輸的動態演變。這些粗粒化模型可以給我們對這些光合作用系統有新的見解，也可以有效的讓我們理解複雜的動力學反應。

To understand complex excitation energy transfer (EET) networks in photosynthetic systems, building a coarse-grained model is necessary to obtain a simplified representation. Here, we developed a systematic approach to produce coarse-grained models for photosynthetic systems by combining a minimum-cut method and a top-down clustering algorithm. The new approach was applied to investigate EET networks of three photosynthetic systems, and we demonstrate that our approach not only reproduces the population dynamics very well but also provides novel insights into the spatial-temporal EET dynamics in complex photosynthetic systems. The new approach could be a very powerful tool towards the elucidation of complex kinetic networks that is commonly encountered in Chemistry.
