摘要翻译:
我们证明了两个光学活性分子之间Forster共振能量转移的量子退相干可以用自旋玻色子模型来描述。这使得我们可以根据实验上可测量的系统参数,给出发色团间激子相干Bloch振荡所必需的定量判据。用荧光共振能量转移(FRET)光谱学对我们的结果进行实验测试是可能的。虽然我们关注蛋白质-色素复合物的情况,但我们的结果也与介质中的量子点和有机分子有关。

英文摘要:
We show that the quantum decoherence of Forster resonant energy transfer between two optically active molecules can be described by a spin-boson model. This allows us to give quantitative criteria, in terms of experimentally measurable system parameters, that are necessary for coherent Bloch oscillations of excitons between the chromophores. Experimental tests of our results should be possible with Flourescent Resonant Energy Transfer (FRET) spectroscopy. Although we focus on the case of protein-pigment complexes our results are also relevant to quantum dots and organic molecules in a dielectric medium.
