HEAT VENT. "Plants regulate light harvesting by photosystem II (PSII) in response to changes in light intensity. One way that plants are able to regulate light harvesting is through turning on and off mechanisms that dissipate excess energy." https://lnkd.in/exqrrHt View in LinkedIn

QUANTUM COHERENCE. "Direct evidence for the presence of quantum coherence over appreciable length scales and timescales in the FMO complex was observed by Engel et al. Since that time a huge body of literature has arisen, and further experiments suggest that the coherence is non-negligible even at room temperature, for up to 300 fs." https://lnkd.in/eRUdQZj View in LinkedIn

QUANTUM COHERENCE under physiological conditions. "The numerical results reveal that electronic coherence persists for several hundred femtoseconds even at physiological temperature." https://lnkd.in/eX8Awwc View in LinkedIn

"THE QUANTUM COHERENCE manifests itself in characteristic, directly observable quantum beating signals among the excitons within the Chlorobium tepidum FMO complex at 77 K. This wavelike characteristic of the energy transfer within the photosynthetic complex can explain its extreme efficiency, in that it allows the complexes to sample vast areas of phase space to find the most efficient path." https://lnkd.in/e7zeiN5 View in LinkedIn

PLANT POWER. "Photosynthetic complexes are exquisitely tuned to capture solar light efficiently, and then transmit the excitation energy to reaction centres, where long term energy storage is initiated." https://lnkd.in/e7zeiN5 View in LinkedIn

PHOTONS STRIKING PLANTS. "Coherent quantum waves can exist in two or more states at the same time, so coherent excitons would be able to move through the forest of antenna molecules by two or more routes at once. In fact, they could simultaneously explore a multitude of possible options, and automatically select the most efficient path to the reaction centre." https://lnkd.in/eDJed9B View in LinkedIn

LONG-LIVED COHERENCE. "Here we extend previous two-dimensional electronic spectroscopy investigations of the FMO bacteriochlorophyll complex, and obtain direct evidence for remarkably long-lived electronic quantum coherence playing an important part in energy transfer processes within this system." https://lnkd.in/eiN8WgU View in LinkedIn

EXCITON'S ORGANIZED MOTION. "Engel et al., have demonstrated... that surprisingly long-lived (>660 fs) quantum coherences between excitonic states play an important role in the dynamics of energy transfer in photosynthetic complexes—i.e., the energy transfer is described by wavelike coherent motion instead of incoherent hopping." http://www.sciencemag.org/content/316/5830/1462 View in LinkedIn

QUANTUM PATHWAYS. "Recent work has documented that light-absorbing molecules in some photosynthetic proteins capture and transfer energy according to quantum-mechanical probability laws instead of classical laws at temperatures up to 180 K. This contrasts with the long-held view that long-range quantum coherence between molecules cannot be sustained in complex biological systems, even at low temperatures." https://lnkd.in/edvYfjM View in LinkedIn

PHOTOSYNTHESIS. "Photons hitting an antenna molecule will kick up ripples of energized electrons — excitons — like a rock splashing water from a puddle. These excitons then pass from one molecule to the next until they reach the reaction centre. But is their path made up of random, undirected hops, as researchers initially assumed? Or could their motion be more organized?" https://lnkd.in/eDJed9B View in LinkedIn
