[Aspuru-Guzik group list] Aspuru Group Meeting Thursday 17th at 2:30 pm in Cabot Division Room

by Felipe Herrera Urbina

Hi everyone, Tomorrow Dr. Changwon Suh will tell us about his latest results on energy storage with flow batteries. Below are the title and abstract of his talk. Best regards, Felipe Herrera Title: *Accelerated Discovery of Small Molecules for Flow Batteries* Abstract: *Small molecules have recently received increasing attention as electrode materials for flow batteries. Current challenges in discovery process of such molecules primarily arise from a huge molecular search space to explore. To identify new electrode materials for flow batteries from a large list of candidate molecules, we developed a virtual library of small organic molecules. This molecular library is actively growing in cooperation with experiments.* *With computationally screened results of a large number of interesting quinone molecules, I am now able to show how the predicted redox behaviors can successfully guide the new experiments by deciphering the important structure-property relationships of the studied molecules. To this end, I will talk about the importance of simple but smart data analysis/visualization. * ------------------------------

[Aspuru-Guzik group list] FW: Excitonics Seminar - Paul McEuen - April 17, 3 pm, 36-428

by Catherine M Bourgeois

Please post and forward to your groups ___________________________________ EXCITONICS SEMINAR SERIES [http://www.rle.mit.edu/excitonics/images/mceuen_001.jpg] Paul McEuen Department of Physics Cornell University Kavli Institute at Cornell for Nanoscale Science Light and Fast: Probing Carriers and Vibrations in 1D and 2D Materials Thursday, April 17, 2014 RLE Conference Room - 36-428 3:00 - 4:00pm Abstract: Carbon nanotubes and 2D atomic membrane materials cut across many disciplines with their remarkable optical, thermal, mechanical, and electronic properties. In this talk we will examine cases when a combination of properties, e.g. optical and mechanical, are simultaneously important. First, we will discuss ultrafast optoelectronic measurements of graphene p-n junctions that probe the fundamental thermal relaxation processes for excited carriers. Next, we will discuss experiments where circularly polarized light creates a valley polarization in an MoS2 monolayer, leading to a Hall effect in the absence of a magnetic field. Finally, we will discuss experiments where individual carbon nanotubes are picked up with micron sized tweezers. These tweezers double as electrical probes, allowing us to simultaneously study the optical, electronic, thermal, and vibrational properties of nanotubes as they are strained or buckled. Bio Paul L. McEuen is the Goldwin Smith Professor of Physics at Cornell University. He directs the Laboratory of Atomic and Solid State Physics and the Kavli Institute at Cornell for Nanoscale Science. His research focuses on nanoscale electronic, optical, and mechanical properties of graphene, nanotubes, and related materials. He received his B.S. degree in Engineering Physics from the University of Oklahoma in 1985 and his Ph.D. in Applied Physics from Yale University in 1991. He joined the faculty at UC-Berkeley in 1992 before coming to Cornell in 2001. Awards and honors include a Packard Foundation Fellowship, a National Young Investigator Fellowship, and the Agilent Europhysics Prize. He is a fellow of the American Physical Society and a member of the National Academy of Sciences. He is also a novelist, and his scientific thriller SPIRAL was named the debut thriller of the year by the International Thriller Writers Association. Light refreshement will be served The Center for Excitonics is an Energy Frontier Research Center funded by the U.S. Department of Energy, Office of Science and Office of Basic Energy Sciences

[Aspuru-Guzik group list] [qip] Fwd: [Lids-seminars] TALK: Wednesday Apr 16th, 3PM, Stephanie Wehner

by aram harrow

Dear quanta, See below for a talk this afternoon. Sorry for the late notice. Aram ---------- Forwarded message ---------- From: "Pablo A Parrilo" <parrilo(a)mit.edu> Date: Apr 14, 2014 11:47 AM Subject: [Lids-seminars] TALK: Wednesday Apr 16th, 3PM, Stephanie Wehner To: "lids-seminars(a)mit.edu" <lids-seminars(a)mit.edu> Cc: Speaker: Stephanie Wehner (National University of Singapore) Date/time: Wednesday 4/16/2014, 3 PM Location: 32D-677 (Stata Center, LIDS seminar room) Title: Entanglement improves classical control Abstract: Electronic devices all around us contain classical control circuits. Such circuits consist of a network of controllers which can read and write signals to wires of the circuit with the goal to minimize the cost function of the circuit's output signal. Here, we propose the use of shared entanglement between controllers as a resource to improve the performance of otherwise purely classical control circuits. We study a well-known example by Witsenhausen from the classical control literature and demonstrate that allowing two controllers to share entanglement improves their ability to control. More precisely, we exhibit a family of circuits in which the the cost function using entanglement stays constant, but the minimal cost function without entanglement grows arbitrarily large. This demonstrates that entanglement can be a powerful resource in a classical control circuit. Joint work with Duy Nguyen Truong and Matthew McKague. Preprint available at http://arxiv.org/abs/1307.1569 Speaker bio: Stephanie Wehner is an Associate Professor in the School of Computing at the National University Singapore and the Centre for Quantum Technologies. Prior to coming to Singapore in 2010, she spent two years as a Postdoctoral Fellow at the California Insitute of Technology, and three and half as a PhD student at the University of Amsterdam. Stephanie is one of the founders of QCRYPT, presently the largest conference in quantum cryptography, and was elected to the Steering Committee of QIP in 2013. Before entering academia, she worked in industry as a professional hacker. Her research interests include quantum cryptography, quantum information theory, and the application of information-theoretic techniques to physics. _______________________________________________ Lids-seminars mailing list Lids-seminars(a)mit.edu http://mailman.mit.edu/mailman/listinfo/lids-seminars _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip

[Aspuru-Guzik group list] CEP Subgroup

by Edward Pyzer-Knapp

Hi all, There will be a CEP subgroup meeting tomorrow 3-4 in the div room. For a change, I will be speaking, abstract below. All welcome Ed ***** *Molecules, Crystals and Materials : Why we care about molecular structure. * *After combinatorially generating molecular structures on a 2D level, the next stage is to move into three dimensions, and create molecular conformations. This, however, is not a trivial task - it involves exploring the conformational landscape * *to discover relevant low lying minima. I will discuss our initial forays into this area, and present some current results to illustrate progress. * *I will also show how the ruggedness of the conformational energy landscape influences our ability to perform predictions of potential crystal structures, and present some ongoing work on the predictions of some materials of interest as OPVs.*
