The Wigner-Weisskopf-type model developed by Alicki and Giraldi [J. Phys. B 44, 154020 (2011)] is applied to the biological process of energy transfer from a large peripheral light harvesting antenna to the reaction center. This process is mediated by the Fenna-Matthews-Olson (FMO) photosynthetic complex with a remarkably high efficiency. The proposed model provides a simple resonance mechanism of this phenomenon employing exciton coherent motion and is described by analytical formulas. A coupling to the vibrational environment is a necessary component of this mechanism as well as a fine-tuning of the FMO complex Hamiltonian. The role of the relatively strong coupling to the energy sink in achieving the resonance condition and the absence of heating of the vibrational environment are emphasized.
由 Alicki 和 Giraldi [J. Phys. B 44, 154020 (2011)] 发展的维格纳-魏斯科普夫型模型被应用于从大的外围光捕获天线到反应中心的能量转移的生物过程。这个过程是由芬纳-马修斯-奥尔森（FMO）光合复合物介导的，其效率非常高。所提出的模型通过分析公式提供了这种现象的简单共振机制，利用激子相干运动。与振动环境的耦合是这种机制的必要组成部分，也是对 FMO 复合物哈密顿量的微调。强调了相对较强的与能量汇的耦合在实现共振条件和振动环境无加热方面的作用。
