Title: Chiral Operators on Hypermultiplet Moduli Spaces
Abstract: This talk will focus on hypermultiplet moduli spaces of various N=2 supersymmetric gauge theories in (3+1)d. In the first part of the talk, we discuss the moduli space of instantons on C^2. For the classical groups, the…

Title: c-theorems in Higher Derivative Gravity
Abstract:
I will discuss c-theorems in the context of AdS/CFT in higher derivative gravity theories. I will focus mainly on D=3 and D=4. I will show that in D=3, demanding the existence of a simple c-function leads to the recently constructed new…

Title: "Projection Hamiltonians for clustered quantum Hall wavefunctions"
Abstract: One of the main measures for determining whether a trial wavefunction for the fractional quantum Hall effect is physically realistic is the properties of an associated projection Hamiltonian, an artificial few-body Hamiltonian constructed so that the given…

Scott Tremaine, IAS "2020 Vision: the Decade Survey in Astronomy and Astrophysics"

Thu, Sep 23, 2010, 4:30 pm – 6:00 pm

Last month the National Research Council completed a massive two-year project to prioritize major projects and other activities in astronomy and astrophysics for the next decade. I will review the process and results, and how they were influenced by the scientific and political landscape and by the successes and failures of past decade surveys. I…

Title: "Measuring the spin dynamics of single atoms with nanosecond time resolution"
Abstract:Spin is a fundamental quantity in quantum mechanics. Its manifestations range from the magnet on our fridge to the magnetic-field dependent splitting of a beam of evaporated atoms in the famous Stern-Gerlach experiment. With the advent of spin-based…

Title: The Black Hole / Qubit Correspondence
Abstract: We present the evidence for an emerging mathematical correspondence between black holes and qubits. We first introduce the relevant parts of quantum information theory and entanglement theory. We then show how the entropy and…

Patrick Lee, MIT "In Search of Majorana"

Fri, Sep 17, 2010, 1:30 pm – 6:00 pm

Abstract:Majorana is a fermion which is its own anti-particle. Often described
as half a fermion, it is expected to have novel braiding properties in 2D, but has never been observed in Nature. Proposals for realizing them in condensed matter center on making vortices in p+ip superconductors. We have found that the Majorana end states which was…

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 …

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

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 mÎ±7. 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…
