Quantum Coherence in Light-harvesting Energy Transfer Cao, Jianshu
Description
Quantum coherence in light-harvesting complexes is explored in a minimal model of V-shape three-level system. We systematically solve the model to predict both its transient and steadystate coherences and demonstrate the interplay of exciton trapping at the reaction center and the non-canonical distribution due to the system-bath coupling [1,2]. Further, we analyze the efficiency and energy flux of the three-level model and show the optimal performance in the intermediate range of temperature and coupling strength, consistent with our understanding of quantum heat engines. [3] Finally, if time allows, we will explain how to generalize the above analysis to complex light-harvesting networks using the waiting time distribution function [4]. $$ $$ [1] Can natural sunlight induce coherent exciton dynamics Olsina, Dijkstra, Wang, Cao, arXiv:1408.5385 (2014/2019) $$ $$ [2] Non-canonical distribution and non-equilibrium transport beyond weak system-bath coupling regime: A polaron transformation approach.

| Description |
Quantum coherence in light-harvesting complexes is explored in a minimal model of V-shape
three-level system. We systematically solve the model to predict both its transient and steadystate
coherences and demonstrate the interplay of exciton trapping at the reaction center and
the non-canonical distribution due to the system-bath coupling [1,2]. Further, we analyze the
efficiency and energy flux of the three-level model and show the optimal performance in the
intermediate range of temperature and coupling strength, consistent with our understanding of
quantum heat engines. [3] Finally, if time allows, we will explain how to generalize the above
analysis to complex light-harvesting networks using the waiting time distribution function [4].
