Absence of selection for quantum coherence in the Fenna-Matthews-Olson complex: a combined evolutionary and excitonic study
Stéphanie Valleau, Romain A. Studer, Florian Häse +5
We present a study on the evolution of the Fenna-Matthews-Olson bacterial photosynthetic pigment-protein complex. This protein complex functions as an antenna. It transports absorb…
Polaritons in Living Systems: Modifying Energy Landscapes in Photosynthetic Organisms Using a Photonic Structure
David M Coles, Lucas C Flatten, Thomas Sydney +8
Photosynthetic organisms rely on a series of self-assembled nanostructures with tuned electronic energy levels in order to transport energy from where it is collected by photon abs…
Efficiency of energy funneling in the photosystem II supercomplex of higher plants
Christoph Kreisbeck, Alán Aspuru-Guzik
The investigation of energy transfer properties in photosynthetic multi-protein networks gives insight into their underlying design principles.Here, we discuss excitonic energy tra…
Chromatic acclimation and population dynamics of green sulfur bacteria grown with spectrally tailored light
Semion K. Saikin, Yadana Khin, Joonsuk Huh +5
Living organisms have to adjust to their surrounding in order to survive in stressful conditions. We study this mechanism in one of most primitive creatures - photosynthetic green…
A stochastic reorganizational bath model for electronic energy transfer
Takatoshi Fujita, Joonsuk Huh, Alan Aspuru-Guzik
The fluctuations of optical gap induced by the environment play crucial roles in electronic energy transfer dynamics. One of the simplest approaches to incorporate such fluctuation…
Temperature and Carbon Assimilation Regulate the Chlorosome Biogenesis in Green Sulfur Bacteria
Joseph Kuo-Hsiang Tang, Semion K. Saikin, Sai Venkatesh Pingali +5
Green photosynthetic bacteria adjust the structure and functionality of the chlorosome - the light absorbing antenna complex - in response to environmental stress factors. The chlo…
