[Aspuru-Guzik group list] ITAMP lunch discussion - Joel Yuen-Zhou, UCSD / MIT (05/22)

by Richard Schmidt

- Please note the different location - Dear colleagues, this week we are looking forward to a talk by Joel Yuen-Zhou from MIT, who will soon be joining the Department of Chemistry and Biochemistry at the University of California San Diego as Assistant Professor. Kind regards, Richard and Swati ITAMP Topical Lunch Discussion Date: Friday, May 22nd Time: 12:00-1:30 pm Pizza will be served. Location: Pratt conference room @ Center for Astrophysics (60 Garden Street) Directions: after entering the lobby of the CfA, go straight to the staircase slightly on your left. Take the stairs downstairs one floor to the basement. Leave the staircase turn right. There is Pratt. Speaker: Joel Yuen-Zhou, University of California San Diego, Department of Chemistry and Biochemistry Title: Spectroscopy and topological phases for organic excitons Abstract: The understanding and control of energy flow at the nanoscale via exciton dynamics is of fundamental chemical and physical interest, but is also technologically relevant for the design of novel light-harvesting materials. In the first part of my talk, I will explain some of our work designing spectroscopic protocols to understand exciton dynamics under coherent illumination via ultrafast Quantum Process Tomography (QPT), a technique which retrieves the time evolution of the quantum state of excitons via nonlinear spectroscopy (1,2). As an application, I will describe the first ultrafast QPT experiment carried out with the Nelson and Bawendi groups at MIT on a nanotubular J-aggregate system at room temperature. I will also clarify the possible relevance of strongly coupled chromophores in natural light-harvesting under incoherent illumination from sunlight (3). Then, I will proceed to explain how one can in principle distinguish excitonic coherences and their vibrational counterparts in nonlinear spectroscopy (4,5). In the last part of my talk, I will describe current work (6) designing topologically nontrivial phases that robustly and selectively move excitons in particular spatial directions of a molecular crystal, simulating solid state “topologically protected” phenomena like the Quantum Hall Effect, which are robust against material imperfections and static disorder. I will end by presenting our most recent work on creating one-way waveguides of plexcitons (strongly coupled excitons and surface-plasmon polaritons). Ref.: (1) J. Yuen-Zhou, Jacob J.

[Aspuru-Guzik group list] [qip] Special Fall 2015 offering: 6.S899 Seminar on Computation and Physics

by Scott Aaronson

Hi everyone, I thought some of you might be interested in the following. All the best, Scott 6.S899 Seminar on Computation and Physics Instructor: Scott Aaronson MIT, Fall 2015 Tuesdays and Thursdays 2:30-4PM in 5-134 This is an advanced graduate course about recent connections between computational complexity and physics, going beyond the fundamental connection established by quantum computing. Topics will include: quantum computing with bosons and fermions (e.g., BosonSampling and FermionSampling); computational aspects of the black-hole firewall problem and the AdS/CFT correspondence; complexity of quantum states and unitary transformations; universality of gates, cellular automata, and billiard-ball models; and quantum computing with closed timelike curves. A major part of the course will be in-class student presentations about recent results. The course is intended for students who have taken a previous quantum computing course, such as 6.845 or 2.111. _______________________________________________ qip mailing list qip(a)mit.edu http://mailman.mit.edu/mailman/listinfo/qip

[Aspuru-Guzik group list] Excitonics Seminar: Ju Li, TODAY May 19, 4:30 PM, 36-428

by Catherine M Bourgeois

Please post and forward to your groups Center for Excitonics Seminar Series Structural design of 2D materials for electronic and optoelectronic applications May 19, 2015 at 4:30 pm/36-428 Ju Li Department of Nuclear Science and Engineering and Department of Materials Science and Engineering [009-cropped-small] abstract In accordance with Richard Feynman's 1959 statement, "there's plenty of room at the bottom," we explore the structural design space of 2D materials for electronic and optoelectronic applications. Homogenous and inhomogeneous elastic strain [Nature Photonics 6 (2012) 866; MRS Bulletin 39 (2014) 108], bending [ACS Nano 5 (2011) 3475], interlayer twist [Nano Letters 14 (2014) 5350] and slip [Nano Letters 15 (2015) 1302] lead to tunable, low-energy artificial atoms, artificial superlattices and pseudoheterostructures that can regulate quasiparticle motion (excitons [Adv. Mater. 26 (2014) 2572], electrons). The amenability of 2D materials for mechanical manipulations, combined with lithographic patterning and annealing [Nanoscale 4 (2012) 4883; PNAS 106 (2009) 10103] could lead to new topological physics [Science 346 (2014) 1344] and device designs. bio Ju Li is BEA Professor of Nuclear Science and Engineering and Professor of Materials Science and Engineering at MIT. His group (http://Li.mit.edu<http://li.mit.edu/>) performs computational and experimental research on mechanical properties of materials, and energy storage and conversion. Ju obtained a PhD degree in nuclear engineering from MIT in 2000, and Bachelor's degree in Physics from University of Science and Technology of China in 1994. He is a recipient of the 2005 Presidential Early Career Award for Scientists and Engineers, 2006 MRS Outstanding Young Investigator Award, and 2007 TR35 award from Technology Reviewmagazine. Thomson Reuters included Ju in its Highly Cited Researchers list in 2014, among 147 scientists world-wide in the Materials Science category. Ju was elected Fellow of the American Physical Society in 2014. The Center For Excitonics Is An Energy Frontier Research Center Funded By The U.S. Department Of Energy,
