Photosynthetic light harvesting: excitons and coherence.
Photosynthesis begins with light harvesting, where specialized pigment-protein complexes transform sunlight into electronic excitations delivered to reaction centres to initiate charge separation. There is evidence that quantum coherence between electronic excited states plays a role in energy transfer. In this review, we discuss how quantum coherence manifests in photosynthetic light harvestin...
متن کاملStrong Coupling of Localized Surface Plasmons to Excitons in Light-Harvesting Complexes
Gold nanostructure arrays exhibit surface plasmon resonances that split after attaching light harvesting complexes 1 and 2 (LH1 and LH2) from purple bacteria. The splitting is attributed to strong coupling between the localized surface plasmon resonances and excitons in the light-harvesting complexes. Wild-type and mutant LH1 and LH2 from Rhodobacter sphaeroides containing different carotenoids...

‡Current address: University of Washington, School of Oceanography, Box 357940, Seattle, WA 98195-7940, USA. †Co first authors. Approximately one-half of the total primary production on Earth occurs in the oceans [1]. Although hundreds of species contribute to oceanic productivity, members of two cyanobacterial genera – Prochlorococcus [2,3] and Synechococcus [4] – are responsible for a signifi...

متن کاملQuantum entanglement in photosynthetic light-harvesting complexes
Light-harvesting components of photosynthetic organisms are complex, coupled, many-body quantum systems, in which electronic coherence has recently been shown to survive for relatively long timescales, despite the decohering effects of their environments. Here, we analyse entanglement in multichromophoric light-harvesting complexes, and establish methods for quantification of entanglement by de...
