摘要

Recent evidence suggests that the multiple charge-separation pathways can contribute to photosynthetic performance.In this work,the influence of coupled-dipoles on photosynthetic performance was investigated in a two-charge separation pathways quantum heat engine(QHE)model.And the population dynamics of the two coupled sites,j-V characteristics,and power involving this photosynthetic QHE model were evaluated for the photosynthetic performance.The results illus-trate that the photosynthetic performance can be greatly enhanced but quantum interference is deactivated by the coupled-dipoles between the two-charge separation pathways.However,the photosynthetic performance can also be promoted by the deactivated quantum interference owing to the coupled-dipoles.It is a novel role of the coupled-dipoles in the energy transport process of biological photosynthetic,and some artificial strategies may be motivated by this photosynthetic QHE model in the future.
