[Aspuru-Guzik group list] Prof. Raymond Kapral visit 12/7

by Johannes Hachmann

Hi everybody, Prof. Raymond Kapral <http://www.chem.utoronto.ca/%7Erkapral/> will be visiting the Boston area to give a talk as part of the shared Harvard/MIT/BU theoretical chemistry seminar series; the talk title and abstract are included below. Prof. Kapral will be visiting the Harvard campus on the afternoon of Tuesday, Dec. 7 (i.e., TOMORROW!!!). We apologize for the short notice, but there may be free slots for student/postdoc meetings between 2:45 and 5:00pm. Please let us know if you are interested to meet the speaker and when you would be available. We will do our best to make it happen. To the non-Aspuru's: Please also forward this eMail to your groups and other potentially interested people. The seminar will be on Wednesday, Dec. 8, 4:00 pm in MIT 56-154. Best regards, Johannes ----------------------------------------------- Dr. Johannes Hachmann Postdoctoral Fellow Aspuru-Guzik Research Group Harvard University Department of Chemistry and Chemical Biology 12 Oxford St, Rm M104A Cambridge, MA 02138 USA eMail: jh(a)chemistry.harvard.edu ----------------------------------------------- ________________________________ Chemically-Powered Nanomotors Biological systems make frequent use of molecular motors to perform tasks such as active transport of material in the cell, cell locomotion and biochemical synthesis. Recently, chemists have fabricated a variety of synthetic nanomotors that use chemical reactions to effect self propulsion. Because of their potential applications, such synthetic nanodevices are being investigated actively. Like their biological counterparts, these nanomotors operate in the regime where they are subject to strong molecular fluctuations from the environments in which they move, and their motion is governed by viscous forces. The first talk will describe recent work on various types of synthetic nanomotors, the means by which they move and some of their possible uses. The second talk will focus on chemically-powered nanodimer motors. In particular the following topics will be considered: simulations of their dynamics, microscopic mechanisms for their motion, how to design motors that beat fluctuations, nonomotor efficienecy and their collective motions.

[Aspuru-Guzik group list] Special Group Meeting Thursday 1pm, Jacob Biamonte

by J D Whitfield

> > We have a special group meeting Thursday December 9, 2010 at 1pm by a visitor to our group, Jacob D. Biamonte, from the Oxford University Computing Laboratory. The location is TBA. > The abstract is here: > *I plan to present results from a study in the use of the mathematics of category theory in the description of quantum states by tensor networks. This approach enables the development of a categorical framework allowing a solution to the quantum decomposition problem. Specifically, given an n-body quantum state S, we found a general method to factor S into a tensor network. Moreover, this decomposition of S uses building blocks defined mathematically in terms of purely diagrammatic laws. We used the solution to expose a previously unknown and large class of quantum states which we prove to be sampled efficiently and exactly. This general framework of categorical tensor network states, where a combination of generic and algebraically defined tensors appear, enhances the theory of tensor network states. Part's of my talk will represent joint work with Stephen R. Clark (CQT, Kebble College, Oxford) and Dieter Jaksch (Oxford, Kebble College, CQT). *

[Aspuru-Guzik group list] Special group meeting Thursday 4 PM, Matt Broome

by Joel Yuen

We have a special group meeting Thursday 21, 4 PM at Naito 030 by a visitor of our group, Matthew Broome, from the School of Mathematics and Physics of the University of Queensland. The abstract is here: *The quantum walk, the quantum version of its classical counterpart the random walk, has received a lot of attention in the past few years both inside and outside of the laboratory. The quantum walk has been proposed as a valuable tool for quantum computation in addition to investigating phenomenon such as Anderson localisation and even energy transport in biological systems. I will give a description of our experimental implementation for the discrete-time quantum walk with single photons in space and show how we tuned the level of decoherence in the system from completely quantum right through to the classical random walk. I will also show the most recent application of the experiment: investigating topological phases with discrete time quantum walks. * -- Joel Yuen-Zhou PhD candidate in Chemical Physics Harvard University CCB, 12 Oxford St. Mailbox 107, Cambridge, MA, USA.

[Aspuru-Guzik group list] Open quantum systems

by Jacob Krich

This article on the arxiv certainly talks the talk. Interested parties may check whether it walks the walk. http://arxiv.org/abs/1012.0364 We have derived for the first time a set of non-Markovian quantum trajectory equations for many-body and multi-state quantum open systems. The exact time-local (time-convolutionless) quantum trajectory equations can be used to simulate quantum dynamics of coupled open systems interacting with a bosonic environment at zero temperature. Our general results are explained and illustrated with several atomic and optical open systems.

[Aspuru-Guzik group list] group travel calendar

by Anna B. Shin

Dear Group, I just shared a calendar called "A-G Group Travel Calendar". When you're not in the office for a period of time, please let me know and I will add this to the calendar. It can be a good resource for everyone. If anyone is looking for you, they can see when you are out and when you'll be returning. Please note: this is a private calendar, not another public group calendar. I will put trips, such as the SERS Program Review meetings on the group travel calendar, not the public one anymore. Thanks, Anna Anna B.
