[Aspuru-Guzik group list] Fwd: Faculty opening in theoretical chemistry at the University of Rochester

by Xavier Andrade

>> Dear colleagues and friends, >> >> The Department of Chemistry at the University of Rochester is conducting a search for a faculty position in theoretical chemistry. The search is primarily for candidates at the junior level, but exceptional senior candidates can also be considered. I am attaching a copy of the ad that will appear in print (C&EN) in the next few weeks. Please alert suitable potential candidates about this opening. >> >> Thanks very much, >> >> Ignacio >> >> -------------------- >> Ignacio Franco >> Assistant Professor · Department of Chemistry · University of Rochester >> ignacio.franco(a)rochester.edu · www.chem.rochester.edu/groups/franco · 585.275.8209 >

[Aspuru-Guzik group list] SLACK - invitation

by Stéphanie Valleau

Dear group, You will each be getting an invitation to SLACK its a super useful tool to communicate with each other / Alan. It's like a group chat in some sense but you can also have private groups etc and upload files which can be useful when you need to send lots of emails on the same topic. I have been using it for today and found it really useful! If you do not get an email invitation from me within a day or so please email me. Cheers, Stephanie

[Aspuru-Guzik group list] Ivan Kassal Visiting Aug 18th - Aug 20th

by Sam Blau

Hey all, Former group member Ivan Kassal (http://www.ivankassal.com/) will be visiting next week on Monday, Tuesday, and Wednesday. He will be giving us a special group meeting on Wednesday the 20th from 11 - 12 in M217. His abstract is below. He is free to meet with group members on the afternoon of the 18th, anytime on the 19th, and has some time before and after his talk on the 20th. Please let me know if and when you would like to meet with him! Sam Abstract: Photosynthetic organisms harvest light using large antenna complexes with many chlorophyll molecules. Because experiments have shown that energy transport through antenna complexes—and onward to a reaction centre—is partially coherent, it has become necessary to treat these processes using computationally expensive techniques from the theory of open quantum systems. This often requires integrating complicated non-Markovian dynamics, followed by averaging over a potentially large ensemble. However, many of the quantum effects observed in photosynthetic complexes are artefacts of the ultrafast laser excitation and are not relevant in incoherent natural illumination. As a consequence, the complete description of energy transport in incoherent light is dramatically simplified. In particular, the often-dubious Markov approximation becomes exact, while the rotating-wave approximation—often unjustified but nevertheless imposed to avoid certain pathologies—becomes unnecessary. With these simplifications, computing any relevant observable is reduced to a problem of linear algebra. This allows a rapid analysis of hypothetical scenarios to determine whether natural light-harvesting architectures are already optimal or whether they could be improved. Although some quantum effects are not important for natural light harvesting, others are nevertheless pronounced. I will provide several examples of light-harvesting complexes where the underlying coherence enhances the transport efficiency and use the techniques described above to show that although some are close to being optimal, others are not.

[Aspuru-Guzik group list] Aspuru Group Meeting Thursday 14th at 2:30 pm in Cv 102

by Felipe Herrera Urbina

(* Note unusual location at Kahne Conference Room in Cv 102.) Hi everyone, Tomorrow Joey Goodknight will talk about applications of 2D optical spectroscopy in photosynthetic complexes. Please see title and abstract below. See you there, Felipe Herrera ----- *Title: *Tracking Excitations in Plants *Abstract:* My talk will be a carefully composed story of how one can track the evolution and development of photo-excitations in a photosythentic protein complex, and why one might want to do such a thing. For those of you in my field reading this: it will be on using polarization-controlled 2-dimensional electronic spectroscopy to perform a quantum process tomography in LH2. My sincerest hope and goal is that the entirety of my talk will be followable by everyone in our research group: from undergrads to Alán.
