Lessons from nature about solar light harvesting
Gregory D. Scholes,Graham R. Fleming,Graham R. Fleming,Alexandra Olaya-Castro,Rienk van Grondelle +4 more
TL;DR: The principles learned from studies of various natural antenna complexes are described and how to elucidate strategies for designing light-harvesting systems are suggested to be used for solar fuel production, to direct and regulate excitation energy flow using molecular organizations that facilitate feedback and control, or to transfer excitons over long distances.
Journal ArticleDOI
Using coherence to enhance function in chemical and biophysical systems
Gregory D. Scholes,Graham R. Fleming,Lin X. Chen,Lin X. Chen,Alán Aspuru-Guzik,Andreas Buchleitner,David F. Coker,Gregory S. Engel,Rienk van Grondelle,Akihito Ishizaki,David M. Jonas,Jeff S. Lundeen,James K. McCusker,Shaul Mukamel,Jennifer P. Ogilvie,Alexandra Olaya-Castro,Mark A. Ratner,Frank C. Spano,K. Birgitta Whaley,K. Birgitta Whaley,Xiaoyang Zhu +20 more
TL;DR: The state of recent discoveries is surveyed, viewpoints that suggest that coherence can be used in complex chemical systems are presented, and the role of coherence as a design element in realizing function is discussed.
Journal ArticleDOI
Efficiency of energy transfer in a light-harvesting system under quantum coherence
TL;DR: In this article, the role of quantum coherence in the efficiency of excitation transfer in a ring-hub arrangement of interacting two-level systems was investigated, mimicking a light harvesting antenna connected to a reaction center as it is found in natural photosynthetic systems.
Journal ArticleDOI
Non-classicality of the molecular vibrations assisting exciton energy transfer at room temperature
TL;DR: In prototype dimers present in a variety of photosynthetic antennae, efficient vibration-assisted energy transfer in the sub-picosecond timescale and at room temperature can manifest and benefit from non-classical fluctuations of collective pigment motions.
Journal ArticleDOI
Energy transfer from Förster-Dexter theory to quantum coherent light-harvesting
TL;DR: In this paper, the authors provide some foundations and perhaps inspirations for new directions of research in the field of energy transfer in multichromophoric systems, and highlight open problems in describing energy transfer beyond standard approximations as well as the need of new approaches to ch...
