[Aspuru-Guzik group list] Fwd: Invitation to the 27th winterschool in Helsinki (Dec 2011)

by Roberto Olivares-Amaya

Hi, Apparently this winter school on excited-state properties is free of charge. I guess that's the charm of doing it in Helsinki during December. Roberto ---------- Forwarded message ---------- From: Michael Patzschke <michaelp(a)chem.helsinki.fi> Date: 2011/11/3 Subject: Invitation to the 27th winterschool in Helsinki (Dec 2011) Dear all, also this year it is my pleasure to anounce that the registration for the "Winter School in Theoretical Chemistry" is now open. The topic of this years school is "Excited-State Properties". It will be held from December 12th–15th, 2011 in Helsinki. For more information see http://www.chem.helsinki.fi/**Info/WinterSchool/ws2011.html<http://www.chem.helsinki.fi/Info/WinterSchool/ws2011.html> At our homepage you can also find more information about previous schools: http://www.chem.helsinki.fi/**Info/WinterSchool/<http://www.chem.helsinki.fi/Info/WinterSchool/> The winter school is free of charge. Of course you need to take care of transportation and hotel rooms yourself. Some information on reasonably priced accomodation can be found on our pages (see the first link). And please do not forget to bring a poster! I hope I will see many of you in Helsinki this december! This is of course a perfect opportunity fo a 2010 summer school reunion :) If you have any questions regarding the school do not hesitate to ask.

by Man Hong

Sounds interesting. Sent to you by Man Hong via Google Reader: Organization of the Bacterial Light-Harvesting Apparatus Rationalized by Exciton Transport Optimization. (arXiv:1111.0069v1 [physics.bio-ph]) via quant-ph updates on arXiv.org on 11/1/11 Authors: Elad Harel Photosynthesis, the process by which energy from sunlight drives cellular metabolism, relies on a unique organization of light-harvesting and reaction center complexes. Recently, the organization of light-harvesting LH2 complexes and dimeric reaction center-light harvesting I-PufX (RC-LH1-PufX) core complexes in membranes of purple non-sulfur bacteria was revealed by atomic force microscopy (AFM)1. Here, we report that the structure of LH2 and its organization within the membrane can be largely rationalized by a simple physical model that relies primarily on exciton transfer optimization. The process through which the light-harvesting complexes transfer excitation energy has been recognized to incorporate both coherent and incoherent processes mediated by the surrounding protein environment. Using the Haken-Strobl model, we show that the organization of the complexes in the membrane can be almost entirely explained by simple electrostatic considerations and that quantum effects act primarily to enforce robustness with respect to spatial disorder between complexes. The implications of such an arrangement are discussed in the context of biomimetic photosynthetic analogs capable of transferring energy efficiently across tens to hundreds of nanometers Things you can do from here: - Subscribe to quant-ph updates on arXiv.org using Google Reader - Get started using Google Reader to easily keep up with all your favorite sites
