[Aspuru-Guzik group list] ITAMP topical lunch discussion: Thursday October 18 @ 12:00

by Mikhail Lemeshko

Dear Friends, On Thursday, October 18, there will be an ITAMP topical lunch discussion. Tea Room (P-226) @ CfA (60 Garden Street) Time: 12:00-1:30 As always pizza will be served. Speaker: Nick Hutzler Title: The ACME Electron Electric Dipole Moment Experiment Abstract: Measurement of a non-zero electric dipole moment (EDM) of the electron within a few orders of magnitude of the current best limit [1,2] would be an indication of symmetry violation [3] that could not be explained within the Standard Model of particle physics. The ACME Collaboration [4] is searching for an electron EDM by performing a precision measurement of electron spin precession signals from the metastable H (^3\Delta_1) state of thorium monoxide (ThO), using a cold and slow beam produced by a novel source [5]. We will discuss the current status of the experiment, including a discussion of statistical and systematic uncertainty.

[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] Volunteer for ITAMP Friday seminar?

by Alan Aspuru-Guzik

Dear group members, We got an invitation by our friend Hossein Sadeghpour, the director of ITAMP to have a group member give a talk to them (in any topic related to AMO/Quantum Information/Excitonics, etc.) on their Friday lunch talk series. If there are any volunteers, please write to me, and I can pick one. The work has to be carried out in our own group of course :) that is the most important selection criteria. Cheers to all, Alan

We are preparing hierarchical assemblies from these chromophores, starting from covalent dimers and trimers, then developing supramolecular assemblies, and engineered crystalline materials to investigate SF in bulk, ordered materials. We are using femtosecond transient spectroscopy as well as time-resolved electron paramagnetic resonance spectroscopy to characterize the SF mechanism and the factors that determine its efficiency at time scales down to 100 fs. We are also using X-ray diffraction to investigate the single crystal structures of these materials and X-ray scattering on their thin polycrystalline solid films to determine how their structures correlate with their ability to carry out SF. Our results suggest that a p-p slip-stacked geometry is important for maximizing SF efficiency.io bio Professor Wasielewski received his Bachelor of Science (1971) and Ph.D. (1975) degrees from the University of Chicago. Following his graduate work, he was a postdoctoral fellow at Columbia University. He then joined the scientific staff of Argonne National Laboratory, where he rose through the ranks to become Group Leader of the Molecular Photonics Group. In 1994, he joined the faculty of Northwestern University, where he is currently the Clare Hamilton Hall Professor of Chemistry. He served as Chair of the Chemistry Department at Northwestern from 2001-2004. He is currently the Director of the Argonne-Northwestern Solar Energy Research (ANSER) Center, which is a DOE Energy Frontier Research Center, headquartered at Northwestern. Professor Wasielewski's research focuses on light-driven charge generation and transport in molecules and supramolecular materials, artificial photosynthesis, molecular systems for solar fuels and electricity, molecular electronics, spin dynamics, spintronics, and time-resolved optical and EPR spectroscopy. His research has resulted in over 410 publications. Professor Wasielewski was elected a Fellow of the American Association for the Advancement of Science in 1995, and has held numerous distinguished lectureships and fellowships. Among Professor Wasielewski's recent awards are the 2012 Arthur C. Cope Scholar Award of the American Chemical Society, the 2008 Porter Medal for Photochemistry, the 2006 James Flack Norris Award in Physical Organic Chemistry of the American Chemical Society, and the 2004 Photochemistry Research Award of the Inter-American Photochemical Society.
