by Dakoulas, Samantha R

ITAMP/HQOC Joint Quantum Sciences Seminar Wednesday, December 13, 2017 4:15 PM, Jefferson 250 Prof. Andrea Cavalleri, Max Planck Institute for the Structure and Dynamics of Matter, Hamburg GERMANY Department of Physics, University of Oxford “Nonlinear THz optics as probe of quantum solids” In this lecture, I will discuss how coherent electromagnetic radiation at infrared and TeraHertz frequencies can be used to collective excitations like phonons in solids. I will emphasize experiments in which hidden features the superconducting order parameter can be revealed. I will also discuss advances in the nonlinear response of phonons, which I will show can be used as a probe of the interatomic potential of a solid. Guest Presentation will begin at 4:30 PM Refreshments will be provided. Thank you, Samantha Dakoulas Faculty Assistant to Professors Lukin & Greiner & their groups Department of Physics 17 Oxford St., Lyman 324A Cambridge, MA 02138 P. (617) 496-2544

[Aspuru-Guzik Group List] Excitonics Seminar-Jillian Dempsey-Tues-Dec 12-rm 36-428

by Catherine M Bourgeois

Please post and forward to your groups Center for Excitonics Seminar Series presents: Proton-Coupled Electron Transfer Processes Underpinning the Production of Renewable Fuels December 12, 2017 at 4:30pm/rm: 36-428 Jillian Dempsey University of North Carolina/Department of Chemistry [http://www.rle.mit.edu/excitonics/wp-content/uploads/2017/08/dempsey_jillia…] The conversion of energy-poor feedstocks like water and carbon dioxide into energy-rich fuels involves multi-electron, multi-proton transformations. In order to develop catalysts that can mediate fuel production with optimum energy efficiency, this complex proton-electron reactivity must be carefully considered. Using a combination of electrochemical methods and time-resolved spectroscopy, we have revealed new details of how molecular catalysts mediate the reduction of protons to dihydrogen and the experimental parameters that dictate catalyst kinetics. While the energy input to drive endergonic fuel-forming reactions is typically supplied indirectly, such as through electricity produced by a solar photovoltaic, we are also exploring excited-state proton-coupled electron transfer reactions that could directly promote catalysis with visible light. This approach represents an energy-efficient mechanism by which solar energy can be captured and converted to chemical energy. Through these studies, we are revealing opportunities to promote, control and modulate the proton-coupled electron transfer reaction pathways of catalysts. Jillian Dempsey is an Assistant Professor of Chemistry at the University of North Carolina. She received her BS from MIT in 2005 and her PhD from California Institute of Technology in 2011. She was a NSF American Competitiveness in Chemistry Postdoctoral Fellow at the University of Washington, Seattle from 2011-2012. She received the UNC Junior Faculty Development Award, NSF CAREER Award, and the Packard Fellowship for Science and Engineering in 2015. In 2016, she was awarded the Air Force Office of Scientific Research Young Investigator Award, and the Sloan Research Fellowship. Research in Dempsey's Inorganic Spectroscopy and Solar Energy Conversion group aims to address challenges associated with developing efficient solar energy conversion processes. They are particularly interested in the charge-transfer processes that will ultimately govern efficiency in solar fuel production devices: proton-coupled electron transfer reactions, electron transfer across the interface between a catalyst and semiconductor, and the reduction of protons to hydrogen. The Center For Excitonics Is An Energy Frontier Research Center Funded By The U.S. Department Of Energy, Office Of Science And Office Of Basic Energy Sciences Light refreshments will be served.

[Aspuru-Guzik Group List] [qip] Spring school on quantum computation at UCSD, March 19-22 2018

by Peter Shor

Forwarded message (from Thomas Vidick). As you may know Shachar Lovett has been organizing a "Trends in Theory" workshop/winter school at UCSD in the past few years. Last year's school was given by Boaz Barak and David Steurer, on Sum of Squares. The next workshop will be on Quantum Computation, March 19-22, 2018. The lecturers are Dorit Aharonov (Hebrew University), David Gosset (IBM), and myself. I am copying below a short description, including a link to the website, that I'd really appreciate if you could forward to the appropriate mailing list. I am also attaching a poster - it would be fantastic if you could print that out and display it somewhere! The school is aimed at graduate students, postdocs and faculty in TCS at large (no quantum information background required). Pleas encourage any graduate students you know who could be interested! We have (very limited) support for a a few students to attend. Thanks, Thomas --------- Spring school on Quantum Computation March 19-22, 2018 University of California, San Diego http://cseweb.ucsd.edu/~slovett/workshops/quantum-computation-2018/ Registration: Registration is free but is required. The deadline is February 1st, 2018. Travel support: We have limited financial support available for students. Please see the website. Overview: The 3.5-day Spring school will bring TCS researchers up to speed on the current excitement in quantum computing. What are the theoretical models for such devices, and what are their prospects? Can they be classically simulated, and if not, can they accomplish algorithmic speed-ups? What are the obstacles to full-blown fault-tolerant quantum computation? And what does all this tell us about complexity theory, cryptography, and quantum information? Target audience: The school is oriented towards graduate students, postdocs and faculty alike. We expect participants to have a background in computer science (complexity and algorithms), as well as a working familiarity with linear algebra, but no prior exposure to quantum information is needed. Topics covered: Emphasis will be put on interesting open algorithmic and computational complexity questions which are of appeal to theoretical computer scientists. The following topics will be discussed: • Basics of quantum mechanics, entanglement, the quantum circuit model, the complexity class BQP, the notion of a local Hamiltonian, and the class QMA (the quantum analog of NP). • Restricted models of quantum computation, such as low-depth circuits and adiabatic computation • Quantum error correcting codes and multiparticle entanglement • Quantum interactive proofs with one or more provers and their connection to cryptography (delegating quantum computations) and complexity (the quantum PCP conjecture). -------------- _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip

[Aspuru-Guzik Group List] ITAMP lunch seminar - Anushya Chandran, Boston University (Dec. 7th)

by Hannes Pichler

ITAMP Lunch Seminar Speaker: Anushya Chandran, (Boston University) Date: Thursday, December 7th Time: 12:00-1:00 pm Includes Pizza. Title: Constraint-driven localization and thermalization Abstract: At low energy, the dynamics of excitations of many physical systems are locally constrained. Examples include frustrated anti-ferromagnets, quantum Hall liquids and Rydberg atoms in the blockaded regime. In this talk, I will discuss the steady states of such systems under their own quantum dynamics. I will first show that a constrained Hilbert space admits a notion of locality and thus adapt the eigenstate thermalization hypothesis (ETH) to this setting. I will then provide numerical evidence in favor of ETH in pinned non-Abelian anyon chains. In the second half of the talk, I will turn to the interplay of spatially random couplings and local constraints. We will find that constraints stabilize localization at strong randomness in different regimes: remarkably, even when the random couplings do not commute with the local constraints. I will discuss the structure of the accompanying quasi-local integrals of motion, the nature of the dynamical transitions and the consequences for near-term quench experiments in Rydberg atomic chains that simulate constrained Ising dynamics. Location: B-106 @ Center for Astrophysics (60 Garden Street) Directions: After entering the lobby of the CfA, turn right to enter the hallway of the B building. In the hallway, turn right again, B-106 will be at the end of the hallway on the left side.
