[Aspuru-Guzik group list] [qip] meeting Friday

by aram harrow

Dear quanta, Let's meet at the usual time and place (11am, 6-310). Please come prepared to talk about what quantum-related subject you've been thinking about for 2 minutes. For most people it is easy to speak for less than 15 seconds or for more than 10 minutes. 2 minutes is surprisingly difficult! aram _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip

[Aspuru-Guzik group list] Away from the Group - Marlon Cummings

by Marlon Cummings

Dear Friends: I will be away on personal leave for 3 weeks starting Feb. 10, 2014. Tomorrow a temporary employee by the name of Velma Dupont will begin a 2-3 week stint, and she be assisting Alan and Cynthia. Her schedule will be 9-3. Cynthia will continue to man the fort and I expect that you all will treat her with respect and kindness while I'm away. I do have eyes and ears in every corner of the lab (Yes, Gian. I see you..). During my time away I will be off the grid -- total blackout (my name is really Jack Bauer). If you have any questions, please see me in person tomorrow and Friday. All the best, Marlon. ---------------- Marlon G.

[Aspuru-Guzik group list] Fwd: [G1] On your mark. Get set. Go!

by Sawaya, Nicolas

Who was interested in doing this? It would be good to get a list together, so would anyone planning on running please email me? You should be training. At least 40km per week. (just kidding. sort of.) cheers, nico Begin forwarded message: From: "Janetzko, John" <jjanetzko(a)fas.harvard.edu<mailto:jjanetzko@fas.harvard.edu>> Subject: [G1] On your mark. Get set. Go!

Undoubtedly, some of you are familiar with this race as running it has been a departmental tradition in the past. This race is a great way to get outside and be active while showing off your lab spirit! :D In the interest of keeping with this tradition (and the spirit of friendly competition) the GPC would like to strongly encourage participation in this coveted event! Participation will involve each lab nominating a team captain to organize the individuals that will be running (and liaise with their PI and lab admin(s) should they be interested in running). I would like for the captains to email me with a list of those that have registered [any time prior to when the scoring will be done – i.e. The morning of the race at the latest]. Staff, feel free to coordinate among yourselves and select a captain, or email me individually as you sign up and I will put you all on the same team. Each lab should aim to have at least five runners complete the race, though more runners are encouraged. Only the rankings of the top five runners in each lab will count towards a lab’s score – that being said, you can still bump other peoples rankings (hence the advantage of more runners). Labs having fewer than five runners will have the last runner’s time (in the department) count for the remaining slots. The winning lab will claim a truly magnificent trophy (that currently resides in the Jacobsen lab) and earn bragging rights for the year! The registration is $35.00 and includes an event shirt and finishers medal. The link to the event is here: http://baevents.com/rasnaheireann/ Please register ASAP since this event frequently fills up prior to race day, and is already half full! Yes, that’s right, there will be ~5,000 people running! As an added incentive, the GPC has ordered headbands (below), which will be FREE for all registered CCB runners! I will send an email when they arrive and the captains may come and pick up one for each runner in their lab (must show registration confirmation). See you at the starting line! --GPC [cid:75BAF96F-0174-41D0-9B2A-2D988A3D1846] _______________________________________________ Ccb-g1 mailing list Ccb-g1(a)lists.fas.harvard.edu<mailto:Ccb-g1@lists.fas.harvard.edu> https://lists.fas.harvard.edu/mailman/listinfo/ccb-g1

[Aspuru-Guzik group list] Special group meeting Friday / Leslie Upton visit

by Stéphanie Valleau

Hi everyone, We have a special seminar coming up on Friday (details copied below) . Leslie will be visiting us for the entire day. I am attaching her schedule for those of you who signed up for meetings with her / lunch. Best, Stephanie ============================ SPECIAL GROUP MEETING When - Friday Feb 7th from 2-3pm Where - Cabot Division room *Quantum Entanglement and Nonlinear Spectroscopy: Non-classical Light Matter Interactions in Organic Molecules* *Leslie Upton, University of Michigan* Quantum entanglement is most commonly known to be utilized in applications for quantum information science, for example quantum computing and quantum cryptography. Yet, very little work has been done studying and characterizing the non-classical light matter interactions in large, organic molecules. The use of entangled photons for multi-photon spectroscopy is a novel technique with several potential applications in entangled two-photon excited fluorescence microscopy, selective two-photon spectroscopy, quantum imaging and remote sensing. In this work, we demonstrate that with the use of entangled photons one can study ETPA scaling properties for large conjugated organic molecules and study molecules with varying absorption properties. This can be done with ten orders of magnitude less photons than classical TPA measurements. Selective absorption of entangled photons is also observed in several organic molecules. A theoretical model is provided to explain this mechanism of non-classical absorption. Through these experiments and theoretical calculations, it is found that while some molecules may have strong classical multi-photon absorption, due to their excitation pathways; these same excitation pathways may hinder the entangled photon absorption process. These entangled photon absorption results provide the first steps in realizing and demonstrating the viability of selective entangled two-photon spectroscopy.

[Aspuru-Guzik group list] [IACS-events] Invitation to the Dean's Lecture on Computational Science, Feb. 14

by Baker, Natasha

Dear IACS Community Members: Hanspeter Pfister and the Institute for Applied Computational Science (IACS) cordially invite you to attend the upcoming Dean's Lecture on Computational Science presented by the Harvard School of Engineering and Applied Sciences on Friday, February 14th. The lecture, entitled "Fast, Accurate Tools for Physical and Biophysical Modeling," will be presented by Leslie Greengard of the Simons Foundation and Courant Institute (NYU). Please find the pertinent details, below. Cheers, Natasha Natasha Baker Administrative Coordinator, IACS 617-496-2623 *************** Title: Fast, Accurate Tools for Physical and Biophysical Modeling Date: Friday, 2/14 Time: Lunch, 12:30pm; Talk, 1-2pm Location: Maxwell Dworkin (Room G115), 33 Oxford Street, Cambridge, MA 02138 Abstract: During the last few years, new algorithms have brought large-scale physical and biophysical modeling within practical reach. The fast multipole method, for example, permits the rapid evaluation of all pairwise interactions in systems of charged particles. If N denotes the number of particles in the system, the cost grows linearly with N rather than quadratically, with million-fold speedups obtained in systems with one billion charges. This is critical, for example, in simulations of electromagnetic phenomena, molecular dynamics, ion channels, and protein-protein interactions. I will give an overview of these methods and their applications, followed by a brief and somewhat speculative discussion of current opportunities at the intersection of applied mathematics, physics, and biology in microscopy, biomedical imaging, systems biology and biophysics. Bio: Leslie Greengard received his Ph.D. degree in Computer Science and his M.D. degree from Yale University in 1987, after completing a B.A. degree in Mathematics at Wesleyan University in 1979. He has been a faculty member at the Courant Institute of New York University since 1989, where he was Director from 2006-20011. He is currently the Director of the Simons Center for Data Analysis at the Simons Foundation, while continuing to serve part-time on the Courant Institute faculty. Greengard and collaborators developed the Fast Multipole Method (FMM) for electromagnetics, the fast Gauss transform for diffusion, and high order accurate methods for a variety of wave propagation problems. He is a member of the National Academy of Sciences and the National Academy of Engineering. _______________________________________________ Iacs-events mailing list Iacs-events(a)seas.harvard.edu https://lists.seas.harvard.edu/mailman/listinfo/iacs-events

[Aspuru-Guzik group list] postdoc candidate talk, next Wednesday, Feb 12, 3-4pm

by Semion Saikin

Dear Group, Next Wednesday we will have a visitor David Gelbwaser from Weizmann Institute. Alan is considering him for a postodoc position. Thus, we ill have all related activities - meeting with the guy, somebody may go for lunch with him (I need to check with Marlon how many people can go), then we will attend the talk, etc. The title and the abstract of the talk are at the end of this email. If you are interested to talk with him please let me know. This is especially important for students who may end up with a postdoc whom they cannot collaborate with. Best, Semion =========================================================== Quantum heat machines efficiency The second law of thermodynamics makes an essential difference between heat and work. Work can be completely transformed to heat in a cyclic process, yet the opposite is not true. While at the classical level there is a standard and well established definition of work, this is not the case at the quantum level. If two quantum systems exchange energy, how is it divided into work and heat? In this talk I will address this question which has important implications on the limits that thermodynamics sets to the performance of quantum devices, in particular to quantum heat machines. D.
