Leonardo Rastelli
Mon, Sep 13, 2010, 2:45 pm – 6:00 pm
Speaker: Leonardo Rastelli Prof. at Stony Brook and YITP Title: Integrability of N=2 Superconformal QCD in the Veneziano Limit Abstract: ``The ${\cal N}=2$ SYM theory with gauge group SU(N) and 2N fundamental hypermultiplets (N=2 SuperConformal QCD for short) is perhaps the simplest 4d gauge theory outside the ``universality class'' of …
Developing label-free optical contrast for biomedical imaging
Fri, Aug 20, 2010, 12:00 pm – 6:00 pm
Speaker: Dan Fu The George R. Harrison Spectroscopy Laboratory Massachusetts Institute of Technology Abstract: Modern microscopy has long been the driving force in tackling biological and biomedical problems. Key innovations in new microscopy technologies are focused on three different aspects: resolution, contrast and speed. Fluorescence…

Condensed Matter Seminar "Metallic conduction and superconductivity in the t-J model: Evolution of the spin states from half filling"
Wed, Aug 11, 2010, 11:00 am – 6:00 pm
Abstract: Many believe, following Anderson, that the origin of the unusual behavior of cuprate superconductors is related to the physics of the undoped phase. However, this connection has not been established theoretically. I will discuss the properties of a renormalized Hamiltonian derived recently from the t-J model, which is required to…
[TESTING BY SSG] Marc Smiciklas, "A Determination of $\alpha$ Using Precision Measurements of Helium Fine Structure"
Tue, Aug 10, 2010, 3:30 pm – 4:00 pm
Recently published theoretical predictions by Pachucki and Yerokhin are in good agreement with the most precise measurements of helium fine structure and, for the first time, represent a complete calculation up to and including terms of order $\alpha^7$. In addition to serving as a test of this theory, more precise measurements could also yield…
A Determination of the Fine Structure Constant Using Precision Measurements of Helium Fine Structure
Tue, Aug 10, 2010, 1:00 pm – 2:00 pm

Recently published theoretical predictions by Pachucki and Yerokhin are in good agreement with the most precise measurements of helium fine structure and, for the first time, represent a complete calculation up to and including terms of order mα7. In addition to serving as a test of this theory, more precise measurements could also yield…
Andreas Wallraff, "Measuring the correlations of a Microwave Frequency Single Photon source"
Wed, Jun 16, 2010, 2:00 pm – 3:00 pm

ABSTRACT: Circuit quantum electrodynamics (QED) allows for excellent control and measurement of the quantum mechanical properties of qubits, photons and their interactions. As a result, circuit QED is an ideal test bed to investigate the quantum nature of light. In our experiments we prepare a complete family of zero and one photon…

Or Sattath, "A Quantum Lovasz Local Lemma"
Thu, Jun 10, 2010, 12:00 pm – 1:30 pm

ABSTRACT: The Lovasz Local Lemma is a powerful tool in probability theory to show the existence of combinatorial objects meeting a prescribed collection of ``weakly dependent" criteria. We present a quantum generalization of this result, which replaces probabilities with a weaker notion of relative dimension and allows to lower bound the…
