- Abstract: In this Article we perform a systematic study of the global entanglement and exciton coherence length dynamics coherence in natural light-harvesting system Fenna-Matthews-Olson (FMO) complex across various parameters of a dissipative environment from low to high temperatures, weak to strong system-environment coupling, and non-Markovian environments. A non-perturbative numerically exact hierarchical equations of motions method is employed to propagate the dynamics of the system. We found that entanglement is driven primarily by the strength of interaction between the system and environment, and it is modulated by the interplay between temperature and non-Markovianity. In contrast, coherence length is found to be insensitive to non-Markovianity. Furthermore, our results do not show the direct correlation between global entanglement and the efficiency of the excitation energy transfer in the FMO complex

We analyse the level coherence of independent green fluorescent protein chromophores and the energy transfer dynamics in homo-dimer green fluorescent proteins.
For different system architectures, we identify a number of very striking features in the dynamics of the chromophore induced by the dielectric relaxation of the environment.
Remarkably, the complex architecture of the green fluorescent protein is well suited to preserving the coherences in the homo-dimer system.
