Title: Phonon-mediated repulsion, sharp transitions and (quasi)self-trapping in the extended Peierls-Hubbard model
Abstract: Particle-phonon coupling is generically expected to lead to a screening of the bare particle-particle interactions. If low-energy overscreening occurs, the resulting attractive interactions are responsible for conventional superconductivity as described by the Bardeen-Cooper-Schrieffer theory. I will demonstrate that Peierls-type particle-phonon coupling not only leads to an enhanced repulsion between identical fermions/hard-core bosons, but also generates an additional effective interaction not of density-density type and thus not involved in screening. This interaction moves pairs of neighbor particles as a whole; this has unusual consequences such as a (quasi)self-trapping transition for a bound pair even when the individual particles are very mobile. These results open new directions in the study and understanding of the effects of particle-boson coupling, relevant for understanding behavior in Physics, e.g. in quantum materials; Chemistry, e.g. in optoelectronic processes; and Biology, e.g. in photosynthesis and DNA.

Dear group members,
As many of you know, I have been as open as possible regarding my decision
to leave the country due to the US situation.
I have accepted and signed last night the offer from the University of
Toronto. I will be starting there officially on July 1st, 2018. We will be
working out transition plans for everybody as discussed in person and group
meeting.
Most of you know it was a difficult decision, but I think it is the best
one for my family and myself.
I am thankful for the support of all of you, especially during this
transition period where I will rely on you regarding work on specifying
equipment, computers, etc. over there.
Also thank you to all of you that are going to move there.
Finally, of course, have a great holiday break and a fantastic 2018. I am
blessed with a fantastic team of people!

Hi all,
If you're in physics you should have heard already, but for the
benefit of all the rest, I'll be defending tomorrow at 10am in 26-214.
If you want or need a break from studying for finals, consider coming to
learn about "Practical fault-tolerant quantum computation". There should
be some breakfast snacks as well. Hope to see you there.
Ted
''Practical fault-tolerant quantum computation''
Presented by Theodore Yoder
Date: Tuesday, December 19, 2017
Time: 10:00
Location: 26-214
Committee: Isaac Chuang, Aram W. Harrow, Marin Soljacic

ITAMP Lunch Seminar
Speaker: Daniel Harlow (MIT)
Date: Tuesday, December 19th
Time: 12:00-1:00 pm
Includes Pizza.
Title: Discrete Holography for Information Theorists
Abstract:I'll review a few puzzling features of the AdS/CFT correspondence, and then show how they arise naturally in simple discrete models which illustrate the quantum error correcting nature of the correspondence.
Location: B-106 @ Center for Astrophysics (60 Garden Street)
Directions: After entering the lobby of the CfA, turn right to enter the hallway of the B building. In the hallway, turn right again, B-106 will be at the end of the hallway on the left side.
Dear quanta
Please see the flier attached for information about Goldstine
Fellowship at IBM Research. This is IBM's prestigious mathematics
postdoctoral fellowship. Please also forward to others who might be
interested (in Machine/Deep Learning, Optimization, Applied Math in
general). I held one myself and highly recommend it.

Hi Ramis,
My colleague Peder Olsen mentioned your name in the context of the
Goldstine Fellowship. I am attaching a flier for the 2018 Goldstine
Fellowship to this email.
May I ask you for your help advertising it to prospective candidates, in-
and outside of IBM (in particular, in the area of machine learning and data
mining)? The application period is open till January 16, 2018.
Your help will be greatly appreciated!
Thanks and best regards,
Jiri Navratil

> This conference follows two previous successful conferences in 2014 and 2016 which asked: if we had a quantum computer, what would we do with it? Then, quantum computers were still hypothetical devices that would use the quantum mechanical properties of superposition and entanglement to solve problems that are likely to be forever out of reach of classical computers. Now, there is a major worldwide effort to build scalable quantum computers to realize crucial, world-changing speedups over classical computers. Even larger quantum computers are being placed online and by 2018, we expect to see the first quantum computers actually outperforming the runtime of classical computers for certain problems. We bring together experts from diverse research avenues to discuss progress in quantum algorithms, identify killer applications of quantum computers, and discuss key challenges in the development of quantum algorithms for existing small- and near-term medium-scale quantum devices. The conference will highlight topics at the forefront of quantum computing, including:
>
> Adiabatic Quantum Optimization and Quantum Annealing
> Quantum Algorithms in the Quantum Circuit Model
> Quantum Query Models
> Quantum Simulation of Physical Systems
> Classical Methods for Simulation of Quantum Algorithms
> Quantum Fault Tolerance and Error Correction
> Quantum Hardware Advances
> Quantum Circuit Optimization
> Quantum Network Protocols
>
>
> The conference will consist of invited talks and poster submissions. There will also be a poster award. Some poster submissions may be considered for contributed talks. Limited travel support is available; please apply in the online application.
>
> Please send this email and information to others who may be interested.
> We hope to see you in Aspen!
