[Aspuru-Guzik group list] Excitonics Seminar: Tyrel McQueen, Tues, Oct 20, 4-349, 4:30 PM

by Catherine M Bourgeois

Please post and forward to your groups ---------------- Probing Electrons and Vibrations in Functional Materials October 20, 2015 at 4:30pm/Pappalardo Room: 4-349* Tyrel McQueen Department of Chemistry, Department of Materials Science and Engineering, Department of Physics and Astronomy, Institute for Quantum Matter, The Johns Hopkins University [TyrelMcQueen] Developing models to predict the behavior of new inorganic solids and design materials with desirable physical properties relies on accurate determination of structure, including the orbital, spin, and charge character of the active electrons. In most real materials, properties are driven by local interactions; however, structural information has typically been constrained to average details from diffraction experiments, or direct imaging of individual atoms/molecules but with the loss of detailed knowledge of the dynamics. Recent advancements in total x-ray and neutron scattering have enabled robust local structure information using pair distribution function (PDF) techniques, which, with appropriate analysis methods, can finally allow us to develop a fundamental understanding of the origin of useful electronic phenomena. In this talk, I will present our recent work on applying chemical group theory methods to the interpretation of PDF data to extract meaningful information about the dynamics in a variety of functional materials. Tyrel McQueen is an Associate Professor of Chemistry at John Hopkins University in Baltimore. He received his BS in Chemistry from Harvey Mudd College in 2004, and his MA (2006) in Chemistry and his PhD (2009) in Chemistry and Materials from Princeton University. His research group is interested in solid state chemistry materials design and synthesis techniques; experimental condensed matter physics, quantum magnetism, and heat- and light-induced charge separation through strong electron correlations; superconductivity.

[Aspuru-Guzik group list] GPU Maintenance Tuesday Oct 20th

by Sam Blau

Hey everyone, RC will be doing maintenance on the aagk80 GPU cluster this coming Tuesday, October 20th. They will be replacing some of the cards that haven't been giving consistent performance and running large-scale benchmarks. On Tuesday they will requeue any jobs that are running and then suspend the queue to do their work. The maintenance and testing will likely take most of the day, after which the queue will be reopened and jobs will begin running again. Please let me know if this is a serious issue for you or if you have any questions. Thanks! Sam

[Aspuru-Guzik group list] Jeremy England Theochem visit meetings

by Sawaya, Nicolas

Hi friends, Michael of the Shakhnovich group asked me to forward this along. #################### Hi everyone, The speaker for next week’s Theochem lecture (see details below) will be Jeremy England from MIT. He’ll be visiting Harvard the day before, on Tuesday, October 20. Unfortunately, he can only be here for two hours in the morning, from9:30 AM to 11:30 AM. If you would like to meet with him during this time, please let me know ASAP — given the short time window, most or all of the meetings will probably have to be in small groups, but let me know if you have any preferences. Many thanks, Michael Jeremy England (MIT), “Statistical Physics of Adaptation” Wednesday, October 21, 4 PM, MIT Building 4, room 163 Many-body systems that are driven far from thermal equilibrium can exhibit a seemingly endless range of different "self-organization" phenomena, whether during long periods of transient relaxation over a hierarchy of timesacles, or in an ergodic steady-state. Indeed, the range of possible behaviors is so diverse that it includes (but is not limited to) everything that living things do! In the face of such phenomenological diversity, it is difficult to articulate any thermodynamic commonality that might be analogous to the tendency to minimize free energy observed in equilibrated systems. Here, we try to exploit recent fundamental progress in our understanding of far-from-equilibrium dynamics to develop predictive thermodynamic principles for a general class of driven self-organized systems. We find there is a language in which Darwinian selection in biological systems may be thought of as a special case of a more general physical tendency for "dissipative adaptation" that arises from the correlation between irreversible changes in shape and the absorption of external work. We close by exploring this hypothesis in different simulation frameworks. ##### Michael Manhart, Ph.D. Postdoctoral fellow Harvard University, Department of Chemistry and Chemical Biology 12 Oxford Street Cambridge, MA 02138, USA Office: Mallinckrodt M-109 Web: http://www.people.fas.harvard.edu/~mmanhart

[Aspuru-Guzik group list] Group Meeting, Oct 15, 2:30 PM, Div Room

by Ian Kivlichan

Hi everyone, Tomorrow Gian will give group meeting at 2:30 PM in the Div Room. The title and abstract are below. This is the last group meeting at the 2:30 PM slot for this semester - next week we switch to the Wednesday 11 slot (so next group meeting will be a week from today on October 21st). Best, Ian ------------------------------------- Speaker: Gian Giacomo Guerreschi Title: Boson Sampling: Towards practical applications and scalable implementations Abstract: Boson sampling, namely the problem of sampling from the output distribution of passive linear optical networks, is strongly believed to be intractable on any classical computer, but efficiently solved with the corresponding quantum optical setup. For this reason, boson sampling attracted a lot of interest in relation to complexity-theoretic questions and it may even offer an experimentally realizable challenge to the Extended Church-Turing thesis. At the same time, current boson sampling realizations with photonic networks present scalability issues, like deterministic single photon generation and detection, which need to be addressed. In this talk, I will show that the successful development of a boson sampling apparatus would not only answer abstract complexity questions, but also yield a practical tool for difficult molecular computations. Specifically, I will show that a boson sampling device with a modified input state can be used to generate molecular vibronic spectra, including complicated effects such as Duschinsky rotations. Finally, I will discuss our recent proposal to implement boson sampling with superconducting circuits. Due to the ability of performing deterministic state preparation and high-fidelity photon detection, we believe that this architecture constitutes the most realistic implementation of fully scalable boson sampling.
