Journal ArticleDOI
Evidence for wavelike energy transfer through quantum coherence in photosynthetic systems
Gregory S. Engel,Gregory S. Engel,Tessa R. Calhoun,Tessa R. Calhoun,Elizabeth L. Read,Elizabeth L. Read,Tae Kyu Ahn,Tae Kyu Ahn,Tomáš Mančal,Tomáš Mančal,Tomáš Mančal,Yuan-Chung Cheng,Yuan-Chung Cheng,Robert E. Blankenship,Graham R. Fleming,Graham R. Fleming +15 more
TL;DR: Previous two-dimensional electronic spectroscopy investigations of the FMO bacteriochlorophyll complex are extended, and direct evidence is obtained for remarkably long-lived electronic quantum coherence playing an important part in energy transfer processes within this system is obtained.
Journal ArticleDOI
Long-lived quantum coherence in photosynthetic complexes at physiological temperature
Gitt Panitchayangkoon,Dugan Hayes,Kelly A. Fransted,Justin R. Caram,Elad Harel,Jianzhong Wen,Robert E. Blankenship,Gregory S. Engel +7 more
TL;DR: Evidence that quantum coherence survives in FMO at physiological temperature for at least 300 fs, long enough to impact biological energy transport is presented, proving that the wave-like energy transfer process discovered at 77 K is directly relevant to biological function.
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
Direct evidence of quantum transport in photosynthetic light-harvesting complexes
Gitt Panitchayangkoon,Dmitri V. Voronine,Darius Abramavicius,Darius Abramavicius,Justin R. Caram,Nick Lewis,Shaul Mukamel,Gregory S. Engel +7 more
TL;DR: Experimental evidence is provided that interaction between the bacteriochlorophyll chromophores and the protein environment surrounding them not only prolongs quantum coherence, but also spawns reversible, oscillatory energy transfer among excited states.
Journal ArticleDOI
Superficially porous silica microspheres for fast high-performance liquid chromatography of macromolecules.
TL;DR: Very fast reversed-phase separations of biomacromolecules are performed using columns made with superficially porous silica microsphere column packings (Poroshell) as discussed by the authors.
