[Aspuru-Guzik group list] [IACS-events] IACS Seminar Friday, November 30: David Lazer (Northeastern University and Harvard University) on Will "Big Data" Yield Big Insights about Human Society?

by Baker, Natasha

Date: Friday, November 30, 2012 Speaker: David Lazer, Professor of Political Science and of Computer and Information Science, Northeastern University; Visiting Research Fellow, Harvard University Location: Maxwell-Dworkin G125, 33 Oxford Street, Cambridge, MA 02138 Time: Informal lunch with speaker, 12:30pm. Talk, 1:00pm. Title: Will "Big Data" Yield Big Insights about Human Society? Abstract: The emergence of "big data" about human behavior combined with ever-escalating computational power offers the possibility of paradigm-shattering research about society. Human behavior is being captured in minute detail as never before--from our political opinions expressed in various social media, to our various personal and professional communications expressed in various electronic forms, to our most intimate questions, as captured by Google. These massive, passive data, however, are not designed for scientific purposes. The objective of this talk is to discuss the scientific opportunities and pitfalls these various data sources offer, as well as to examine institutional barriers to the development of a computational social science. Bio: David Lazer is Professor of Political Science and of Computer and Information Science at Northeastern University, as well as a visiting research fellow at Harvard. He is a leading figure in the areas of computational social science and network science, with papers in such journals as Science, PNAS, Public Opinion Quarterly, and the American Political Science Review.

[Aspuru-Guzik group list] big news - soda maker and newbies!

by Anna B. Shin

Group, Cynthia and I picked up a soda maker for the kitchen's beverage station. The brand is SodaStream (Dynamo LX model). If you want to use it, you must purchase your own soda bottles due to unsanitary conditions of sharing bottles - they get disgusting and it's recommended to replace the bottles every couple years. Here's a link to the SodaStream brand of bottles (although you might be able to find similar bottles at a cheaper price): http://www.sodastreamusa.com/Carbonating-Bottles-C17.aspx Alan assigned Martin to be the CO2 gas master, so he will be in charge of filling up the carbonator when it runs out. I copy Gian Giacomo, new postdoc starting February 1 as well as Marlon who will be replacing me. Marlon's first day is Mon 26 Nov. My "official" last day is Fri 30 Nov. Yes, I know my last day was Sep 28, but that morphed into my "unofficial" last day for the group. Haha, we tricked ya, sort of. Oh yeah, I'll be popping in and out in December just to make sure yall don't suffer Anna-withdrawal and of course help with transition. P.S. If you don't have a group duty, then you'll be getting one very soon. More time-consuming duties like Web Master (Jacob) will exempt you from having more than 1 duty. Simple duties like Gas Master (Martin) will mean you get more duties. I'll make sure to brief Marlon on group stuff and that includes the desk queue. Bye! Anna B.

[Aspuru-Guzik group list] Soda maker

by Martin Blood-Forsythe

Dear group, The soad/seltzer maker is now set-up. For sanitation purposes you will need to purchase your own bottle before using it: http://www.sodastreamusa.com/Carbonating-Bottles-C17.aspx (get the PET bottle, not the glass carafe). I think it might also be possible to pick up bottles at Tags Hardware in Porter Sq. or at Staples in Harvard Sq. Usage instructions: (I'm happy to help out with showing you how to use it the first time if you want to come find me) 1. Fill carbonating bottle with very cold water to wavy line. (chill water in fridge) 2. Push tilt lever (shiny silver lever on top front), and screw the bottle into the machine. Make sure that the CO2 nozzle is extending into the water. (IMPORTANT: Never carbonate anything other than water. Add flavor AFTER). 3. The carbonating button is the large silver button on rear top. Press this all the way down in a firm, short motion until you hear a loud buzz, then release button. Repeat 2+ times (3 buzzes is a "standard level of fizzy"). 4. Push the tilt lever back, releasing the seal with the carbonator. Unscrew the bottle. 5. Flavor your fizzy water if you wish by tilting the bottle and slowly pouring in sodamix or some juice etc. Important: - Carbonating bottles should NOT be put in the dishwasher or otherwise heated or scratched. Rinse out with soap and water. - Add flavor only after carbonating. - Since this is going to be used by many people, make sure that you disinfect your soda bottle before screwing it into the soda maker. You may want to label your own bottle with a sharpie too. Let me know if there are any problems with it (e.g. if the gas is running low). Best wishes, -Martin

[Aspuru-Guzik group list] [qip] TALK: Monday Nov 19th, 11AM, Stephanie Wehner

by Thomas Vidick

Stephanie Wehner from CQT Singapore will be visiting CTP and CSAIL from Monday-Friday. She's giving a talk on Monday in the LIDS seminar, and it should be of interest to many of us. The talk is related to the de Finetti theorem; abstract follows. --------------------- Speaker: Stephanie Wehner (National University of Singapore) Date/time: Monday 11/19/2012, 11 AM Location: 32D-677 (Stata Center, LIDS seminar room) Title: Convergence of SDP hierarchies for polynomial optimization on the hypersphere Abstract: We show how to bound the accuracy of a family of semi-definite programming relaxations for the problem of polynomial optimization on the hypersphere. Our method is inspired by a set of results from quantum information known as quantum de Finetti theorems. In particular, we prove a de Finetti theorem for a special class of real symmetric matrices to establish the existence of approximate representing measures for moment matrix relaxations. Joint work with Andrew Doherty (U. of Sydney). Preprint available at http://arxiv.org/abs/1210.5048 . Speaker bio: Stephanie Wehner is a computer scientist at the Centre for Quantum Technologies, National University of Singapore, born in Wuerzburg, Germany. She studied at the University of Amsterdam and obtained her Ph.D. at CWI, before moving to Caltech as a postdoctoral researcher under John Preskill. Since 2010 Wehner is an assistant professor in the department of computer science at the National University of Singapore. _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip

I will present a complementary approach: instead of developing new and exotic materials, work with semiconductor heterostructures, materials whose properties are simple and well-established. Then use nanolithography to carve them into a set of coupled electron droplets, designed to match a Hamiltonian of interest. Nanopatterned electrodes can be used to tune many important parameters. I will describe how we can achieve pseudospin-resolved transport and spectroscopy through a many-body system, testing previously inaccessible theory. (1) I will also explain plans to extend these ideas to systems of multiple coupled local sites, as a model for quantum criticality in heavy-fermion systems, as well as to conduct some of the first phase-sensitive transport measurements on many-body systems. (2) I will also give a brief overview of my group's other work on electrons in low-dimensional systems, from graphene to topological insulators to complex oxides. > > For announcement poster please go to: http://www.physics.harvard.edu/events/colloquium.pdf > > > > > > > > > > > > > >

[Aspuru-Guzik group list] [Aspuru-meetings-list] group meeting this Friday: Jacob Sanders

by Ryan Babbush

Hi Everyone, This Friday Jacob Sanders will present his research during our usual group meeting time (2:30) in the usual group meeting place (Division Room). His abstract is included below. See you all there! Title: Compressed Sensing for Molecular Spectroscopy Abstract: Compressed sensing is a processing algorithm that significantly reduces the number of measurements needed to accurately resolve signals. Here we demonstrate how this technique can be used to increase resolution in theoretical modeling of molecular spectra and in post-processing of experimental data. As a first illustration, we use compressed sensing to extract information from the real-time simulation of atomic and molecular systems, including one-dimensional vibrational, electronic absorption, and circular dichroism spectra. We show that, compared to the standard discrete Fourier transform approach, the total propagation time, and hence the computational cost, can be reduced by a factor of five. As a second example, we introduce a two-dimensional variant of compressed sensing and apply it to the data obtained from phase-modulated ultrafast spectroscopy experiments. For the model system of atomic rubidium vapor, we obtain an order-of-magnitude (about 10-fold) improvement in spectral resolution along each dimension, as compared to a conventional discrete Fourier transform, using the same data set. More attractive is that compressed sensing allows for random undersampling of the experimental data, down to less than 5% of the data set, with essentially no loss in spectral resolution. By combining powerful resolution with ease of use, compressed sensing can be a useful tool for the prediction and interpretation of molecular spectra. -- 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
