| 摘要: | 为了获得两类光合作用系统Fenna-Matthews-Olson (FMO)和Phycoerythrin545 (PE545)在能量传输过程中的动力学演化, 首先通过对Ohmic、Debye和Adolphs and Renger (AR)谱密度进行参量化计算, 然后将计算结果应用到TNL(时间非局域)方法中, 计算出FMO和PE545的动力学演化过程. 结果表明, Ohmic、Debye和AR谱密度参量化后的结果与原谱密度在足够大的频率范围内吻合,而且对比其他方法计算的FMO和PE545的动力学演化过程, 该方法计算得到的结果足够精确, 其对满足TNL方法要求的可参量化的谱密度函数的扩展是正确的, 可用于光合系统的动力学计算. |
| Abstract: | In order to investigate the evolution of the dynamics of two kinds of photosynthesis systems, that is, Fenna-Matthews-Olson (FMO) and Phycoerythrin 545 (PE545) complexes, we parameterize the Ohmic, Debye and Adolphs and Renger (AR) spectral density functions and then calculate the dynamics of the FMO and PE545 complexes using the TNL method with the special Lorentzian form of the three different spectral density functions. The result shows that the parametrization is in great agreement with the original spectral density function, and the evolution of the population of the two complexes with different spectral density functions is valid. The work proves that the result that has been done on the range of the spectral density functions is correct, and using the TNL method with the parametrization the dynamics of the lager systems in dissipative enviro- nments can be calculated. |
