[Aspuru-Guzik group list] [Aspuru-meetings-list] Aspuru group meeting: Professor Carlos Pineda

by Ryan Babbush

Where: Mallinkrodt Division Room When: This Friday, 2pm What: This week Professor Carlos Pineda will be visiting the group and presenting research at our normal group meeting. An abstract of his talk is included below. Markovianity in quantum systems ========================= We discuss the definition of quantum markovianity, and study two random matrix models, one with strong coupling (which presents non markovianity) and the other one with a tunable interaction (which serves to study the limits of the validity of the Markovian approximation). We also study several examples in which the degree of chaoticity can be tuned, to understand the relation between chaos and markovianity. -- 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] special group meeting on Thursday at 4:00 pm

by sarah mostame

Dear Group Members, Christina Kraus from Innsbruck (group of Prof. Peter Zoller) is visiting Harvard this week and will present a talk on Thursday in Aspuru-Guzik group. She will talk about Majorana fermions in optical lattices, including a long introduction to Majoranas. Here are the title and abstract: When: Thursday, 9 August, 4:00 pm Where: CCB Division Room What: Talk by Christina Kraus Title: Probing Atomic Majorana Fermions in Optical Lattices Abstract: Topological phases of matter, as they are appear e.g. in fermionic insulators and gapped superconductors, are not only of fundamental interest in the theory of condensed matter physics, but their understanding is also of central importance for the realization of a topological quantum computer. Here, the topologically protected zero energy modes, called Majorana fermions, serve as the basic building blocks for computation. However, despite an intense theoretical and experimental effort, mostly in the field of condensed matter systems, the detection of Majorana fermions is elusive so far. In this talk I will explain a different approach to this problem that relies on the clean realization and manipulation of many-body systems of cold atoms in optical lattices. Starting from a one-dimensional lattice system whose phase diagram includes topological states of different symmetry classes, I will explain how standard quantum optical methods available in current experiments can be used to detect the presence and number of Majorana fermions as well as to probe the form of their wave function.

[Aspuru-Guzik group list] Aspuru-Guzik group meeting tomorrow, 2pm

by Ryan Babbush

Hello Everyone, Tomorrow at 2pm in the CCB Division Room Supriya Shrestha will be presenting for the Aspuru-Guzik group weekly meeting. For those of you on the "aspuru-meetings-list" and not "aspuru-list", our group did not disappear or stop having group meetings; rather, the new person in charge of sending these emails (me) did not know that I was supposed to send to both lists until this week. Supriya will be presenting on two research projects and the abstracts are included below. 1) Accurate Fundamental Gap Calculation Using Density Functional Theory The fundamental gap is defined as the difference between ionization potential and electron affinity of a molecule and getting accurate fundamental gaps has been a long standing problem in DFT. I have been working on developing a robust, computationally inexpensive and easily generalizable method to calculate the fundamental gap of molecules. Moreover, DFT calculations are sensitive to basis sets and exchange correlation used, therefore I also studied the effect of the choice of basis set on the gap. I will focus the talk on three methods that I have been experimenting with and their performance in predicting the gaps of the G2 set. 2) Charge and Energy Transfer in Confined Fullerene Units Along Polymer Chains Non-covalent interactions play an important role in determining the optical and electronic properties of organic semiconductors. Therefore we are interested in knowing if we can control non-covalent interactions by confining the organic semiconductor units along polymer chains. An experiment was done using the organic semiconductor C60 and an increase in mobility by an order of magnitude was seen in the polymers. We did charger transport studies on these C60 systems to theoretically explain this increase in mobility. Now we are developing an excitonic transfer model for these systems to see if we find a similar trend. -- 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-Guzik group list] Group screen

by Xavier Andrade

Hello everybody, This is an email to tell you/remind you about the screen outside of M-105. The idea of this screen is to show information about the group research. Currently it is a bit forgotten, Johannes is probably the only person actively uploading content. So, to renew the content it is _mandatory_ for each group member to upload one slide about her/his research with the group before August 31. I am attaching an example slide prepared by Alán in MS Powerpoint format, that you can use as a base for your slides. Of course you can use other style or other software to generate the images. The contents is uploaded and controlled from a simple web interface: https://group:web13AsGu@caral.chem.harvard.edu/ You can upload images (ideally with size 1920x1080 pixels), pdf documents and videos (see the web interface for details). Please contact me if you have questions or problems regarding the screen and its web interface. Thanks, Xavier

[Aspuru-Guzik group list] Extravagant dinners hosting group visitors

by Alan Aspuru-Guzik

Dear group members, Two recent very extravagant bills arrived yesterday. Some of you took our visitor to a very fancy place using the limited group unrestricted funds that we use for this purpose. I have been fortunate of having quite decent group members that have not abused the system and had been reasonable with expenses, but now we got two *very* expensive bills in a row. We might have to now put an explicit cap on your per capita expenses and number of people in the dinner, or limit the number of places that you can go to. This is a reminder to be *moderate* when you take out postdoctoral interviewees, and that extravagant expenses do not make me and Anna very happy. Please don't do this again! We might have to end/modify a good group tradition if I notice a single additional abuse. Alan
