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

by Catherine M Bourgeois

Please post and forward to your groups ________________ 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."

[Aspuru-Guzik group list] [IACS-events] Onassis Foundation University Seminar, Monday, 9/24: A.S. Fokas on Ancient Greeks, Mathematics and Neuroscience

by Baker, Natasha

Monday September 24, 2012 1:30-2:30 in MD G135 "Ancient Greeks, Mathematics and Neuroscience" A.S. Fokas Abstract: After reviewing the position of Plato for the existence of innate knowledge, tabula inscripta, and the opposing position of Aristotle and Locke that the human mind is a tabula rasa, certain philosophical positions of the Ancient Greeks about Mathematics, will be recalled. The above positions will then be discussed within the context of the astounding modern achievements of Neuroscience. In particular, 'bottom up' processes which are basically innate, and 'top down' processes which rely on experience stored in memory, will be discussed. In addition, the importance of different time scales in conscious and unconscious processes will be elucidated. Finally, it will be shown that modern brain imaging techniques provide an important example of the crucial role played by Mathematics in understanding the essence of various phenomena, a fact which was philosophically appreciated first by Pythagoras. Bio: A.S. Fokas has a BSc in Aeronautics from Imperial College (1975), a PhD in Applied Mathematics from the California Institute of Technology (1979) and an MD from the University of Miami, School of Medicine (1986).

[Aspuru-Guzik group list] [Aspuru-meetings-list] group meeting tomorrow!

by Ryan Babbush

When? 2:00pm tomorrow (Friday). Where? The Mallinkrodt Division Room? What?... At long last Jon Welch will be presenting his research after we pushed him back on the group meeting schedule every week for 5 weeks straight! He probably doesn't believe it, but he's actually going to present this time. The title and abstract can be found below. Optimal Mappings of Physical Hamiltonians and Arbitrary Diagonal Operators for Quantum Simulation ============================================= Universal digital quantum simulation relies on the ability to construct sequences of elementary quantum operations (gates) that produce a faithful representation of the unitary operators governing the dynamics of the simulated system. The task of developing quantum circuits that accurately represent these operators can often prove to be highly nontrivial. In general such circuits require the use of an exponential number of gates as well as a large number of ancillia (or working) qubits. In many instances, the unitary operators are diagonal, or can be made so through application of an efficient quantum circuit that changes to the operator’s eigenbasis. In this talk we will discuss a new approach for mapping such diagonal operators to optimal quantum circuits that are faithful representations of the operator, and require no ancilla qubits. Additionally, we will discuss how to extract the essential differential structure of the operator that allows us to greatly reduce the complexity of the circuit to one that is polynomial in the number of gates. -- Ryan Babbush | PhD Student in Chemistry (949) 331-3943 | babbush(a)fas.harvard.edu Harvard University | Aspuru-Guzik Research Group 12 Oxford Street, Box 400 | Cambridge, MA 02138 _______________________________________________ Aspuru-meetings-list mailing list Aspuru-meetings-list(a)lists.fas.harvard.edu https://lists.fas.harvard.edu/mailman/listinfo/aspuru-meetings-list

[Aspuru-Guzik group list] [Aspuru-meetings-list] AMP Seminar Monday, September 24, Nimrod Moiseyev (Technion-Israel Institute of Technology) Novel phenomena in light matter interactions based on universal control of asymmetric pathways of quantum states.

by Gonzalo Gonzalez Abad

Please join us for a seminar sponsored by the Atomic and Molecular Physics Division, Harvard-Smithsonian Center for Astrophysics. (Complete schedule at http://www.cfa.harvard.edu/amp/events.html) 11:00 AM Monday, September 24, 2012 Phillips Auditorium 60 Garden St, Cambridge, MA Title: Novel phenomena in light matter interactions based on universal control of asymmetric pathways of quantum states. Nimrod Moiseyev Schulich Faculty of Chemistry and Faculty of Physics, Technion-Israel Institute of Technology and ITAMP (visiting Fall 2012) Abstract In this talk, we will introduce fundamental phenomena in decaying systems, unravel a variety of new effects, identify their physical observables, and propose experimental settings to observe them. The rich complex dynamics in decaying open quantum systems has always been very hard to analyze with traditional tools of quantum mechanics. Hence, many fascinating effects occurring during such processes remained unraveled. Non-Hermitian quantum mechanics offers avenues to analyze the dynamics in such systems. In principle, the new phenomena that will be described can be calculated by using the standard (hermitian) description of QM. However, they can not be explained, predicted, or designed without the calculations of non-hermitian degeneracies (known as exceptional points). In the next coming weeks, a series of lectures (a mini course) will be given on the use of non-hermitian QM to calculate resonances and on the methods which are needed to calculate EPs and their effects on the dynamical behavior of the systems under study. Simple problems will be solved. The participants in the mini course are invited to propose new directions of research based on their work and experience. _______________________________________________ Aspuru-meetings-list mailing list Aspuru-meetings-list(a)lists.fas.harvard.edu https://lists.fas.harvard.edu/mailman/listinfo/aspuru-meetings-list
