[Aspuru-Guzik group list] Free black vinyl couch-bed with 3 storage drawers

by Aspuru

Dear group members, Dori and I are rearranging furniture at home and will not need this couch-bed anymore. It cost us originally 500 back in the bay area circa 2005. We used to have it in our living room when I was a postdoc. It is well preserved and has great storage drawers. It is *free* to the first group member that agrees to come to my house (Cambrigeport) and take it away before next Saturday when we have other furniture come in. It is great as a guest bed! I will send another picture of it in the next message. Again, first come, first-serve. Alan Aspuru-Guzik Associate Professor Harvard University http://aspuru.chem.harvard.edu Sent from my mobile. Please pardon any typos.

[Aspuru-Guzik group list] [IACS-events] IACS Seminar Friday, September 21: Joseph Teran (UCLA) on Scientific Computing for Movie Special Effects and Virtual Surgery

by Baker, Natasha

Speaker: Joseph Teran, Associate Professor of Mathematics, UCLA Location: Maxwell-Dworkin G125, 33 Oxford Street, Cambridge, MA 02138 Time: Informal lunch with speaker, 12:30pm. Talk, 1:00pm. Title: Scientific Computing for Movie Special Effects and Virtual Surgery Abstract: Dr. Joseph Teran will talk about some exciting new applications of scientific computing for solid and fluid mechanics problems including the simulation of virtual materials for movie special effects, video game effects and virtual surgery. These new applications all have an increasing demand for physically realistic dynamics of materials like water, smoke, fire, brittle objects, elastic objects, etc. The computational demands arising in these applications are somewhat different than those traditionally considered by scientific computing researchers and many new algorithms are needed to address them. Dr. Teran will discuss these new scientific computing challenges as well as some recent algorithms developed in his lab to address them. Virtual surgery is a particularly exciting application area. A virtual surgery simulator is like a flight simulator for training surgeons (and would-be surgeons) in modern procedures. Dr. Teran will also discuss procedures related to repair and manipulation of soft-tissues. Other topics discussed will include GPU and manycore algorithms for real-time solution of nonlinear elliptic equations arising in elasticity problems and in incompressible flow, cut-cell methods for higher-order accuracy on structured grids and contact algorithms for thin structures. Bio: Joseph Teran is an associate professor of applied mathematics at UCLA. His research focuses on numerical methods for partial differential equations arising in engineering. This includes computational solids, computational fluids, multi-material interactions, fracture dynamics and computational biomechanics. One very exciting example of this research is virtual surgery. These techniques allow a surgeon to practice a given procedure on the computer rather than on a cadaver or patient. Other exciting applications include computer graphics and movie special effects at Walt Disney Animation. Teran was a recipient of a 2011 Presidential Early Career Award for Scientists and Engineers (PECASE) and a 2010 Young Investigator award from the Office of Naval Research. In 2008, Discover Magazine named him one of the 50 “Best Brains in Science.” For information about the future events at IACS, see http://iacs.seas.harvard.edu/events.

[Aspuru-Guzik group list] [IACS-events] IACS Seminar Friday, October 5: David Cox (Harvard MCB/CBS) on Leveraging High-Performance Parallel Computing for Biologically Inspired Object and Face Recognition

by Baker, Natasha

Speaker: David Cox Location: Maxwell Dworkin G125, 33 Oxford Street, Cambridge, MA 02138 Time: Informal lunch with speaker, 12:30pm. Talk, 1:00pm Title: Leveraging High-Performance Parallel Computing for Biologically Inspired Object and Face Recognition Abstract: The visual cortex of the human brain is unrivaled by artificial systems in its ability to recognize faces and objects in highly variable and cluttered real-world environments. Biologically inspired computer vision systems seek to capture key aspects of the computational architecture of the brain. Such approaches have proven successful across a range of standard object- and face-recognition tasks. However, since the number of parameters in a vision model is typically large, and the computational cost of evaluating one particular parameter set is high, when a model fails we are left uncertain whether it is because we are missing a fundamental idea, or because the correct "parts" have not been tuned correctly, assembled at sufficient scale, or provided with enough training. In this talk, I'll present a high-throughput search approach for exploring a broad range of biologically inspired vision models. I'll discuss parallel programming techniques that enable this approach, including machine-learning-guided metaprogramming techniques that bring the ideas of high-throughput search down to the level of implementation-level code optimization. Bio: David Cox is an assistant professor in the Department of Molecular and Cellular Biology and the Center for Brain Science at Harvard. He completed his PhD in the Department of Brain and Cognitive Sciences at MIT with a specialization in computational neuroscience. Prior to joining MCB/CBS, he was a Junior Fellow at the Rowland Institute at Harvard, a multidisciplinary institute focused on high-risk, high-reward scientific research at the boundaries of traditional fields. His laboratory seeks to understand the computational underpinnings of high-level visual processing through both reverse and forward engineering. The group employs a wide range of experimental techniques to probe natural systems, while at the same time actively developing practical computer vision systems based on what is learned about the brain.

by Stéphanie Valleau

Hi everyone, I'll be giving group meeting today *when*: 2-3pm *where*: cabot division room *what*: On the alternatives for a spectral density from QM/MM calculations* ** abstract *** *The bath two-time correlation function plays a central role in describing * * the dynamics of systems when using Open Quantum System approaches. * *In this talk, I will explain how one can extract this quantity / the spectral * *density by using a QM/MM approach. I will then overview various semi-classical * *corrections which aim at recuperating the quantum bath correlation function * *from the classical one. In the QM/MM approach one typically introduces an * *energy gap correlation function: I will show models which can account for this * *quantity and how these lead to some of the previously introduced semi-classical * *corrections. All considerations will be applied to the photosynthetic * *Fenna-Matthews-Olson complex.* ** -- Stéphanie Valleau PhD student in Chemical Physics Harvard University CCB, 12 Oxford St. Mailbox 312, Cambridge, MA, USA

[Aspuru-Guzik group list] ITAMP/HQOC Joint Quantum Sciences Seminar, Prof. Charles Adams, October 3rd

by Joan Hamilton

HQOC/ITAMP Joint Quantum Sciences Seminar Wednesday, October 3rd, 4:00 PM, J250 Guest Presenter: Prof. Charles S. Adams, Durham University Talk title: Photon-photon interactions using cooperative non-linear optics. Abstract: Ever since the invention of the laser, the field of non-- linear optics has been at the forefront of progress in optical information and communication technologies. However, one area where non--linear optics has been constrained by fundamental physics is the control of photons at the single quanta level. We address this issue using an alternative type of optical non--linearity that is mediated not directly by the interaction between light and matter, but indirectly by the interaction between light--induced excitations, i.e., dipole-dipole interactions. For example, the giant dipoles associated with highly excited Rydberg states can induce a cooperative response of say 1000 neighbouring atoms, thereby greatly amplifying the effect of each photon. In this talk I will present some interesting consequences of this cooperative response including light induced phase transitions and optical bistability.

[Aspuru-Guzik group list] Excitonics Seminar, TODAY, Sept 27, 3PM, 36-428

by Catherine M Bourgeois

TODAY Center for Excitonics Seminar Series Thursday, September 27, 2012 RLE Conference Room - 36-428 3:00 - 4:00pm SOLUTION-PROCESSED SOLAR CELLS USING COLLOIDAL QUANTUM DOTS TED SARGENT - University of Toronto, Canada Abstract: Solution-processed photovoltaics offer a cost-effective path to harvesting the abundant resource that is solar energy. The organic and polymer semiconductors at the heart of these devices generally absorb visible light; however, half of the Sun's power reaching the Earth's surface lies in the infrared. Solution-processed solar cells that harvest wavelengths beyond 1 μm were first reported in 2005, and were based on the application of quantum-size-effect-tuned infrared-bandgap colloidal quantum dots. Since then, we have reported externally-certified solar power conversion efficiencies exceeding 7%. Recent advances of interest include all-quantum-tuned tandem solar cells; and the emergence of all-inorganic colloidal quantum dot materials that use halide anions, instead of conventional organic ligands, for passivation. I will summarize advances in the materials chemistry, fabrication, physical understanding, and performance-oriented engineering of colloidal quantum dot solar cells and light sensors. Bio Ted Sargent received the B.Sc.Eng. (Engineering Physics) from Queen's University in 1995 and the Ph.D. in Electrical and Computer Engineering (Photonics) from the University of Toronto in 1998. He holds the rank of Professor in the Edward S. Rogers Sr. Department of Electrical and Computer Engineering at the University of Toronto, where he holds the Canada Research Chair in Nanotechnology. His book The Dance of Molecules: How Nanotechnology is Changing Our Lives (Penguin) was published in Canada and the United States in 2005 and has been translated into French, Spanish, Italian, Korean, and Arabic. He is founder and CTO of InVisage Technologies, Inc<http://www.invisageinc.com/Default.aspx>. He is a Fellow of the AAAS "...for distinguished contributions to the development of solar cells and light sensors based on solution-processed semiconductors." He is a Fellow of the IEEE "... for contributions to colloidal quantum dot optoelectronic devices."
