Abstract
摘要

In the process of photosynthesis, energy transfer in light-harvesting protein complexes is efficient and robust. Recent 2D electronic spectroscopes have identified the long-lived quantum coherence in several natural light-harvesting systems. Within a quantum dynamic framework, we observed optimal energy transfer due to the competition of quantum coherence and bath-induced dissipation. The optimization can behave in various parameters, including reorganization energy, temperature, spatial-temporal correlation of bath, etc. To further reveal the nontrivial quantum effects, we compared results from quantum dynamics and classical hopping kinetics. Although hopping kinetics can successfully predict the optimization phenomenon, the dominant energy transfer pathway can be strongly affected by multi-site quantum coherence.
