论文摘要
Fenna-Matthews-Olson（FMO）细菌叶绿素（BCHLS）是由绿色硫细菌的光合作用过程中高效能量转移负责的分子，这与长期相干性的量子现象有争议。这种现象是使用量子开放系统（QoS）建模的，而没有包含周围的记忆效应，该周围的记忆效应近似于热平衡上的声子浴。这项工作应用了运动方法的分层方程（HEOM），一种非马克维亚方法，在FMO复合物的系统演化中建模，以在量子激发期间与全局和半局部纠缠一起对相干时间量表进行预测。
Fenna-Matthews-Olson (FMO) bacteriochlorophylls (BChls) are molecules responsible of the high efficiency energy transfer in the photosynthetic process of green sulfur bacteria, controversially associated to quantum phenomena of long lived coherence. This phenomenon is modelled using Quantum Open Systems (QOS) without included memory effects of the surrounding approximated as a phonon bath on thermal equilibrium. This work applies the Hierarchical Equations of Motion method (HEOM), a non-Markovian approach, in the modelling of the system evolution of the FMO complex to perform predictions about the coherence time scales together with global and semi-local entanglement during the quantum excitation.
