[Aspuru-Guzik group list] Meet Moshe Shapiro today

by Felipe Herrera

Dear group, This is a friendly reminder that today we are having Moshe Shapiro with us at 3:15 pm in the Division Room. As a conversation starter, let me point out a paper he published last year questioning the claims that quantum coherence plays a role in biology: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3511749/ This meeting seems to be the ideal opportunity for those of us interested in quantum biology to hear from the author about this point of view and hopefully start a small debate. Have a great day, Felipe

[Aspuru-Guzik group list] ITAMP topical lunch discussion: Thursday October 10 @ 12:00

by Mikhail Lemeshko

Dear Friends, On Thursday, October 10, there will be an ITAMP topical lunch discussion. Tea Room (P-226) @ CfA (60 Garden Street) Time: 12:00-1:30 As always pizza will be served. Speaker: Richard Schmidt Title: The Bose Polaron - Challenges for Quantum simulation with ultra cold atoms Abstract: We study the properties of the Bose polaron, an impurity strongly interacting with a Bose-Einstein condensate, using a field-theoretic approach and make predictions for the spectral function and various quasiparticle properties that can be tested in experiment. We find that most of the spectral weight is contained in a coherent attractive and a metastable repulsive polaron branch. We show that the qualitative behavior of the Bose polaron is well described by a T-matrix approximation. We discuss the implications of our results for the attempted quantum simulation of the Froehlich Hamiltonian using ultra cold atoms. Looking forward to seeing you there, Misha Lemeshko -- Dr. Mikhail Lemeshko Institute for Theoretical Atomic, Molecular, and Optical Physics (ITAMP) Harvard-Smithsonian Center for Astrophysics MS-14 60 Garden St. Cambridge, MA 02138 U.S.A. mlemeshko(a)cfa.harvard.edu http://sites.google.com/site/mishalemeshko/ Tel. +1 (617) 496-7610 Fax +1 (617) 496-7668

[Aspuru-Guzik group list] [qip] seminar Oct 11?

by aram harrow

Dear quanta, I might give a seminar next Friday at 1:30pm on my recent paper on product-state approximations to ground states. However, it conflicts with Jelani Nelson's talk on dimension-reduction algorithms in the MIT/MSR reading group: http://people.csail.mit.edu/madhu/reading-group/ In case this conflict matters to you (i.e. you really want to attend both) can you please tell me? If many people object, I can speak in a different week. aram _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip

[Aspuru-Guzik group list] FW: [Seas-faculty] [Ee-seminars] Electrical Engineering Seminar October 11, 2013

by Hamilton, Joan

[hseas-logo] Harvard EE Seminar Series 3-4PM Friday, October 11, 2013 Maxwell Dworkin G125 Reception immediately to follow Mind the gap: quantum effects and optical magnetism in plasmonic particle junctions Jennifer Dionne Materials Science and Engineering Stanford University Electrons and photons can coexist as a single entity called a surface plasmon—an elementary excitation found at the interface between a conductor and an insulator. Plasmons are evident in the vivid hues of rose windows, which derive their color from small metallic nanoparticles embedded in the glass. They also provide the basis for color-changing biosensors, photo-thermal cancer treatments, improved photovoltaic cell efficiencies, and nano-optical tweezers. While most applications have relied on classical plasmonic effects, quantum phenomena can also strongly influence the plasmonic properties of nanometer-scale systems. In this presentation, I’ll describe my group’s efforts to probe plasmon modes spanning both classical and quantum domains. We first explore the plasmon resonances of individual nanoparticles as they transition from a classical to a quantum-influenced regime. Then, using real-time manipulation of plasmonic particles, we investigate plasmonic coupling between pairs of particles separated by nanometer- and Angstrom-scale gaps. For sufficiently small separations, we observe the effects of quantum tunneling between particles on the plasmonic resonances. Finally, using the properties of coupled metallic nanoparticles, we demonstrate the colloidal synthesis of an isotropic metafluid or "metamaterial paint" that exhibits a strong magnetic response at visible frequencies. By combining the electric and magnetic resonances of non-magnetic nanoparticles, this metamaterial can achieve negative permeabilities and refractive indices. The ability to assemble, probe, and control both classical and quantum plasmonic junctions with electric and magnetic resonances may enable new opportunities in fields ranging from catalysis to molecular opto-electronics. Bio: Jennifer Dionne is an assistant professor in the department of Materials Science and Engineering at Stanford University. Jen received B.S. degrees in Physics and Electrical & Systems Engineering from Washington University in St. Louis in 2003, and a Ph.D. degree in Applied Physics from the California Institute of Technology in 2009, under the supervision of Prof. Harry Atwater. She joined Stanford in 2010 following a postdoctoral research fellowship at the University of CA, Berkeley and Lawrence Berkeley National Laboratory, working with Prof. Paul Alivisatos. Jen’s research develops new optical materials for applications ranging from high-efficiency solar energy conversion to bioimaging and manipulation. This research has led to demonstration of negative refraction at visible wavelengths, development of a subwavelength silicon electro-optic modulator, development of quantum plasmonic materials, design of new optical tweezers for nano-specimen trapping, and demonstration of a metamaterial fluid. Her work has been recognized with a NSF CAREER Award, AFOSR Young Investigator Award, Outstanding Young Alum award from Washington University in St. Louis, Hellman Fellowship, and the Materials Research Society Gold Award. In 2011, she was named one of Technology Review's TR35 - 35 international innovators under 35 tackling important problems in transformative ways.

[Aspuru-Guzik group list] More Learning - The Power Of Electricity

by Trepte, Kai

Hi Everyone: Some of you may have noticed that Flaskbox was not updating this morning. This is because there was a power issue over in the Rhino building over the weekend and the computer that was monitoring Flaskbox was shut down killing the process. We have made some adjustments (monitoring Flaskbox in the background) so that if there are more power issues, Flaskbox should not be affected. As always if you have any suggestions please let us know how we can improve. Thank you for all the support as we move through alpha testing. With Respect, Team Flaskbox

[Aspuru-Guzik group list] Aspuru-Guzik Lab Survey

by Marlon Cummings

Good afternoon, friends: As you know, we are in the planning stages of the Aspuru-Guzik laboratory renovation/remodeling project. Our first meeting was very informative and productive, and now we are seeking your input. Please take a few minutes to complete this survey, and do so prior to *Monday, October 7, 2013. * https://docs.google.com/forms/d/1-9eKUDGveVJc5erzhPAoi2JVTn92C609tOLiN1vd7C… Our goal is to forward this data to the planning committee before the next meeting. As information comes in, we will update the group accordingly. Your feedback is greatly appreciated. We thank you, Team Aspuru-Guzik

[Aspuru-Guzik group list] Meet Prof. Moshe Shapiro at 3:15 pm on Wed 9th @ Division Room

by Felipe Herrera

Dear group, I am delighted to announce that this Wednesday at 3:15 pm we will have Prof. Moshe Shapiro with us at the Division Room. He will be available for scientific discussion for about 30 min before the HQOC/ITAMP Joint Quantum Sciences Seminar starts. This is a great opportunity to discuss your research with one of the brightest chemical physicists in the field. Moshe is also a very nice person with a broad interest in science, so I encourage you to participate in the meeting. Moshe Shapiro was a postdoc here in Harvard Chemistry some time ago. Years later he co-founded the field of coherent control and over the years has made several contributions to AMO physics as well. For instance, he invented the now standard method of photo-associating ultracold atoms to form deeply bound cold diatomic molecules. Actually, the department's newest faculty Kang-Kuen Ni used this method to produce ultracold KRb molecules back in 2008. Best, Felipe
