If anybody wants to give an impromptu group meeting with some hot results of their own, let me know ASAP. Otherwise, I can give group meeting today, for example about the Clean Energy Project results, basically the talk I gave at MIT in February.

[Aspuru-Guzik group list] [Aspuru-meetings-list] Group meeting by Sule tomorrow

by Joel Yuen

When: Friday April 14 from 11:30 AM to 12:30 PM Where: Cabot Division Room at Mallinckrodt What: Group meeting by Sule " The story of DA2T and some tricky charge transport parameters" formal abstract: The design and screening of novel organic semiconductors in silico, prior to undertaking chemical synthesis could create new opportunities for rational semiconductor design. We report of a theoretical screening study of eight novel derivatives of the high-performance dinaphtho[2,3-b:2’,3’-f]thieno[3,2-b]thiophene semiconductor. Recently, this molecule has demonstrated mobilities as high as 8.3 cm2V-1s-1. Our study identifies a novel compound expected to demonstrate a two-fold improvement in mobility over the parent molecule. Synthetic and electrical characterisation of the compound is reported with single crystal field-effect transistors, indeed showing a two-fold improvement in mobility to 13.7 cm2V-1s-1. This is one of the very few organic semiconductors to show mobilities greater than 10 cm2V-1s-1. informal abstract: DA2T is a novel high-mobility organic semiconductor for OFET applications discovered by theoreticians. But theoreticians cannot publish new molecules without experimental support easily. We were lucky to have it synthesized and indeed show an exceptional mobility. We had a small library of 7 molecules and could eliminate 5 of them based on only the molecular parameters. For the remaining two we optimized crystal structures to see how they pack and then calculated the electronic couplings among the packed molecules. Finally based on classical charge transfer theories, for DA2T we estimated a mobility which would be higher than pentacene as well as its parent compound. This study provides insights into the tricky world of charge transfer parameters in organic molecular crystals and provide some guidance towards screening of millions of molecules over the World Community Grid: The Clean Energy Project. -- Joel Yuen-Zhou PhD candidate in Chemical Physics Harvard University CCB, 12 Oxford St. Mailbox 107, Cambridge, MA, USA. _______________________________________________ Aspuru-meetings-list mailing list Aspuru-meetings-list(a)lists.fas.harvard.edu http://lists.fas.harvard.edu/mailman/listinfo/aspuru-meetings-list

In space, a coherent beam breaks into a multitude of speckles. In the spectral domain, the pulse is strongly modified due to the random transmission of the sample. Both effects are deleterious for one's ability to use coherent techniques for the spectral analysis of the sample. I will review our ongoing work aimed at implementing nonlinear spectroscopy with coherent broadband laser pulses that have passed through opaque samples. Our goal is to use the quasi-random spectrum of light for extracting spectral information [1,2]. At the same time, we use two-dimensional spatial light modulators to correct for the spatial and temporal distortions due to the multiple scattering in opaque samples. [1] E.A. Shapiro, S.O.

[Aspuru-Guzik group list] How "quantum" is the exciton dynamics in the Fenna-Matthews-Olson complex?. (arXiv:1104.2031v1 [cond-mat.mes-hall])

by Man Hong Yung

Sent to you via Google Reader How "quantum" is the exciton dynamics in the Fenna-Matthews-Olson complex?. (arXiv:1104.2031v1 [cond-mat.mes-hall]) Authors: Peter Nalbach, Daniel Braun, Michael Thorwart We present numerically exact results for the quantum coherent energy transfer in the Fenna-Matthews-Olson molecular aggregate under realistic physiological conditions, including also vibrational fluctuations of the protein and the pigments. We find that although the coherence times are to some extent reduced as compared to the often assumed Ohmic fluctuation spectrum, the exciton dynamics is far from being a classical hoping process. We quantify the "quantumness" of the energy transfer as distance of the density matrix to the classical pointer states for the energy current operator. Sent from my iPhone

[Aspuru-Guzik group list] Quantum Beer at Queen's Head

by J D Whitfield

Dear Hellerites and Aspuru-Guzikites, Cesar told me to take up the reigns on scheduling quantum beer. We'll be having a good time this Thursday at 6:00 at The Queen's Head. (Good time comes with with minimum uncertainty hbar/2, so let's make it as coherent as possible.) To the folks at Alan's group -- I don't know how to message the group. Can you show me how or forward this email to that list? Cheers and happy tunneling! Douglas
