[Aspuru-Guzik group list] ANNOUNCEMENT: Excitonics Seminar, Tues, Mar 15, 3 pm, 36-428

by Cathy Bourgeois

Please forward to your groups and post in your area ______________________________________ Center for Excitonics Seminar Series Announcement Tuesday, March 15, 2011 3:00 PM RLE Conference Room: 36-428 PAUL E. BURROWS, Reata Research "HOW MANY SCIENTISTS DOES IT TAKE TO CHANGE A LIGHTBULB? - The challenge and potential of organic solid state lighting" Abstract: Many scientific papers and presentations in the field of organic electronic materials have kicked off with bold statements implying a route to low cost, large area manufacturing. Organic solid state lighting has recently become feasible due to dramatic improvements in the efficiency and operating lifetime of organic light emitting devices (OLEDs) and, again, dramatic visions of efficient, large area organic lighting on plastic sheets akin to wallpaper fill the popular literature. These improvements have led to the widespread, if perhaps not yet profitable, exploitation of OLEDs in small area displays, particularly for handheld devices. Application to general lighting, however, presents unique challenges distinct from the displays industry. Organic solid state lighting indeed has advantages over other available technologies but simply applying display technology to lighting is probably not the way to go. This presentation will start from what is actually required to light a room, how much value a lighting product can command, and which problems therefore exist that still require research breakthroughs for their solution. Bio: Currently, Dr. Burrows consults on fundamental science, technology and policy for business and government in nanotechnology, molecular materials and energy through Reata Research in Chattaroy, Washington. His specialties include: organic materials and devices for SSL, thin film encapsulation, hybrid organic-inorganic semiconductor integration, 3D electronic devices, thin film deposition techniques for organic molecules and salts, and production/analysis of ultra-high purity organic materials. From 2000 to 2008, Paul served as Laboratory Fellow for Pacific Northwest National Laboratory where he managed a $5 million budget for the Nanoscience and Nanotechnology Initiative and worked with DOE and Next Generation Lighting Industry Alliance to define and build our national program in solid state lighting. Dr. Burrows has also led nanoscience research programs at numerous industry and academic institutions, including Princeton University, University of Southern California, and the Laboratory for Nonlinear Optics and Advanced Materials at the Riken Institute in Japan.

by tempel＠physics.harvard.edu

Might be of interest to people working in open systems... ---------------------------- Original Message ---------------------------- Subject: [CMT Kids] Kids' seminar TODAY@noon, at Lyman 425. From: kids(a)physics.harvard.edu Date: Tue, March 8, 2011 8:17 am To: "CMT Kids' Seminars" <kids(a)physics.harvard.edu> -------------------------------------------------------------------------- Time and Place: 03/08 at noon, Lyman 425 Speaker: Yosi Avron (Technion) Title: Geometry of quantum response in open systems Abstract: I shall describe a theory of adiabatic response for open systems governed by Lindblad evolutions. The theory gives quantum response a geometric interpretation induced from the geometry of Hilbert space. For a two level system the metric turns out to be the Fubini-Study metric and the symplectic form the adiabatic curvature. Nice things happen when the metric and symplectic structures are {\em compatible}. I shall give examples of compatible physical systems. Based on joint work with Fraas, Graf and Kenneth (http://arxiv.org/abs/1008.4079). _______________________________________________ Kids mailing list Kids(a)physics.harvard.edu http://physics.harvard.edu/mailman/listinfo/kids

Please forward to your groups and post in your area ______________________________________ Center for Excitonics Seminar Series Announcement Tuesday, March 8, 2011 3:00 PM RLE Conference Room: 36-428 Vinod M Menon, Queens College of CUNY "CONTROL OF LIGHT-MATTER INTERACTION USING DISPERSION ENGINEERED PHOTONIC STRUCTURES" Abstract: Coherent interaction of an ensemble of dipole active atoms or excitons with vacuum electromagnetic field has been studied extensively since its initial conception by Dicke in 1954. However, when the emitters are not only periodically arranged, but are also placed in a periodically modulated dielectric environment, the interaction between them is carried by the electromagnetic Bloch waves of the photonic crystal. This coherent interaction results in the formation of strongly coupled light-matter quasiparticles called Bloch polaritons. In this talk I will discuss our recent work demonstrating the formation of such quasiparticles in a periodically arranged multiple quantum well system. Tuning of these polariton states using electric field and its application for switching and slow light enhanced nonlinear optics will also be discussed. Following this I will discuss our recent work on dispersion engineered metamaterials for controlling the spontaneous emission rate of quantum dots. Unlike microcavity structures that rely on localization of electromagnetic field for increase in the photon density of states, the present work exploits the flat dispersion in anisotropic materials to create more states for the emitter to emit through. Finally I will briefly discuss our work on nonreciprocal optical elements realized using quasiperiodic photonic crystals embedded with colloidal quantum dots. Bio: Dr. Vinod. M. Menon is an Associate Professor of Physics at Queens College and Graduate Center of the City University of New York (CUNY). He joined CUNY as part of the Photonic Initiative in 2004. Prior to joining CUNY he was a research staff member at Princeton University (2003-04). He joined Princeton as the Lucent Bell Labs Post Doctoral Fellow in Photonics in 2001. He received his MSc in Physics from the University of Hyderabad, India in 1995 and his Ph.D. in Physics from the University of Massachusetts in 2001. His current research interests include the development of classical and non-classical light sources using quantum dots, metamaterials for controlling light-matter interaction, and engineered nonlinear optical materials using hybrid nanocomposites.

[Aspuru-Guzik group list] [Aspuru-meetings-list] photovoltaics seminars tomorrow

by Johannes Hachmann

Hi everybody, There are three photovoltaics talks at MIT tomorrow which may be of interest to people. Best Johannes 1) Organic and Dye Sensitized Solar Cells Michael McGehee Associate Professor of Materials Science and Engineering and Director of the Center for Advanced Molecular Photovoltaics, Stanford University Tuesday, March 8 4:15 PM Room 66-110 Organic solar cells and dye sensitized solar cells are very promising because they can be deposited rapidly in roll-to-roll coating machines without expensive vacuum chambers or high temperature processing. Since they can be lightweight and flexible, it may soon be possible to roll them onto rooftops at a cost several times lower than is now possible with silicon or cadmium telluride solar cells. Since organic semiconductors do not contain any rare or toxic elements, such as indium, cadmium or tellurium, organic solar cells could be used to provide the world with a significant fraction of its electricity. My research group has used synchrotron x-ray diffraction and other characterization techniques to reveal in detail how semiconducting polymer chains and fullerene molecules pack in solar cells and shown how this packing influences the electronic processes that determine how well solar cells work. We have also measured the lifetime of polymer solar cells and found it to be as high as 7 years. We have also pioneered the use of long range Forster energy transfer to improve light absorption in solar cells. We believe that the incorporation of energy relay dyes into dye sensitized solar cells (DSCs) is going to make it possible to raise their efficiency from 11 to 15% in the next few years by extending the region of the spectrum that the cells can absorb farther out into the infrared, where almost half of the sun's energy is located. One of the great challenges to making highly efficient solar cells with solution deposited films that have high defect densities is keeping the films thin so the charge carriers can be collected before recombination occurs while at the same time absorbing all of the light. We have recently demonstrated that absorption and power conversion efficiency can be increased by as much as 20% simply by nanoimprinting an array of domes into the active layer before depositing a silver electrode so that incoming light can be coupled into plasmonic modes that travel in the plane of the solar cell. Michael D. McGehee is an Associate Professor in the Materials Science and Engineering Department and Director of the Center for Advanced Molecular Photovoltaics at Stanford University. His research interests are patterning materials at the nanometer length scale, semiconducting polymers, large area electronics and renewable energy. He has taught courses on nanotechnology, organic semiconductors, polymer science and solar cells. He received his undergraduate degree in physics from Princeton University and his PhD degree in Materials Science from the University of California at Santa Barbara, where he did research on polymer lasers in the lab of Nobel Laureate Alan Heeger. He did postdoctoral research with Galen Stucky and Brad Chmelka at the University of California at Santa Barbara on the self-assembly of organic-inorganic mesostructures. He has won the 2007 Materials Research Society Outstanding Young Investigator Award and the Mohr Davidow Innovators Award. 2) "CONTROL OF LIGHT-MATTER INTERACTION USING DISPERSION ENGINEERED PHOTONIC STRUCTURES" Vinod M Menon, Queens College of CUNY Tuesday, March 8, 2011, 3:00 PM RLE Conference Room: 36-428 Coherent interaction of an ensemble of dipole active atoms or excitons with vacuum electromagnetic field has been studied extensively since its initial conception by Dicke in 1954.

by Jarrod McClean

Hi All, Stephanie and I are putting together the group recruitment poster for our visiting prospective graduate students who arrive this Friday! To get a good spread of what is going on in the group, we ask that if you have a graphic and maybe a few bullet points on what you've been working on, please send it to us, and we will integrate it into the poster! This is a good chance to publicize and perhaps recruit a new minion to help you in the coming years. If you plan to contribute, please do so by Wednesday so we have a margin of error for printing. This is important to Alan, so he sends his thanks in advance! ~Jarrod & Stephanie
