标题： Quantum Excitation Transfer in an Artificial Photosynthetic Light-Harvesting System

摘要： 我们解析地推导了一个人工光收集光合作用系统的传递概率和效率，该系统由一个环与中心受体耦合组成。 对于一对入射光子，我们在弱耦合区域发现接近完美的单激发传递效率，并且双激发传递可以忽略不计。在强耦合区域，单激发传递效率大于90\%，而双激发传递效率约为50%。 我们已经发现决定高传递效率的三个主要因素是大的受体概率、长的受体衰减时间和强光子-环耦合。 还讨论了将该理论框架应用于仿生太阳能设备的可能性。 显示英文摘要

摘要： We analytically derive transfer probabilities and efficiencies for an artificial light-harvesting photosynthetic system, which consists of a ring coupled to a central acceptor. For an incident photon pair, we find near-perfect single excitation transfer efficiency with negligible double excitation transfer in the weak coupling regime. In the strong coupling regime, single excitation transfer efficiency was greater than 90%, while the double excitation efficiency was approximately 50%. We have found that the three main factors which determine high transfer efficiencies are large acceptor probabilities, long acceptor decay times, and strong photon-ring coupling. A possible implementation of the theoretical framework to bio-inspired solar energy devices is also discussed.
