摘要：

The high efficiency in excitation energy transfer observed in the Fenna-Matthews-Olson light-harvesting complex in green sulfur bacteria is due to its arrange of photo-pigments, called bacteriochlorophylls. They are central for the photosynthetic process of those bacteria being controversially associated to long-lived coherence. The study of this protein complex and its energy dynamics continues, trying to understand the environmental factors affecting it. This work explores the temperature effects in the behaviour of entanglement and coherence among bacteriochlorophyll excitation energy transfer within the Fenna-Matthews-Olson complex, considering the latest pigment-protein monomer arrangement of 8 bacteriochlorophylls. An analysis for the system evolution using the Hierarchical Equations of Motion method, a non-Markovian approach, is performed to get the global and semi-local entanglement, as well as the coherence in the system.
