Mon, Sep 30, 2013, 2:30 pm to 3:30 pm
"In this talk I will discuss the problem of counting 1/16 BPS operators in N=4 Super-Yang-Mills theory at weak coupling. I will present the complete set of 1/16 BPS operators in the infinite N limit, which agrees with the counting of free BPS multi-graviton states in the gravity dual AdS5xS5.

Condensed Matter Seminar, Yigal Meir, "Kondo Physics in Quantum Point Contacts"

Mon, Sep 30, 2013, 1:15 pm to 2:30 pm
Quantum point contacts (QPCs) are the basic building blocks of any mesoscopic structure, and display quantized conductance, reflecting the quantization of the number of transparent channels. An additional feature, coined the "0.7 anomaly", has been observed in almost all QPCs, and has been a subject of intensive debate in the last couple of...

Mon, Sep 30, 2013, 12:00 pm to 1:00 pm
“From Genotype to Phenotype: a physics perspective”
Lunch @11:45.

From building blocks to large galaxies: Towards understanding the formation of the Milky Way - Anna Frebel, MIT- Special Seminar

Fri, Sep 27, 2013, 12:00 pm to 1:30 pm
Abstract: The early chemical evolution of the Galaxy and the Universe is vital to our understanding of a host of astrophysical phenomena. Since the oldest, most metal-poor stars are relics from the high-redshift universe; they probe the chemical and dynamical conditions of a time when large galaxies first began to assemble.

Hamilton Colloquium Series - Andrei Bernevig, Princeton University: "Topological States of Matter"

Thu, Sep 26, 2013, 4:30 pm to 5:30 pm
Topological states of matter distinguish themselves from quantum ordered states - such as antiferromagnets - by the absence of a local order parameter. Their properties are remarkable, and range from realizing Majorana fermions to exhibiting fractional statistics and non-abelian braiding.

HET Informal Seminar - Ehsan Hatefi, ICTP, Trieste, Italy

Tue, Sep 24, 2013, 3:30 pm to 4:30 pm
BPS, Non-BPS and D-brane anti D-brane Effective actions in type II Super string theory with their corrections to all orders in alpha-prime

HET Informal Seminar - IAS - Barak Kol, Racah Institute of Physics, “How Perturbative Field Theory Could have been Discovered in Einstein's Gravity"

Tue, Sep 24, 2013, 1:30 pm to 2:30 pm
It will be argued that essentially all the deep concepts of perturbative quantum field theory could have been discovered in non-quantum (classical) field theories. These include Feynman diagrams, effective actions, divergences, regularization, renormalization and field doubling (the Closed Time Path formalism).

High Energy Theory Seminar - IAS - Xiao-Gang Wen, Perimeter Institute - Topological Order and Long-range Entanglement

Mon, Sep 23, 2013, 2:30 pm to 3:30 pm

High Energy Theory Seminar - Aron Wall, University of California, Santa Barbara - Superselection Sectors in AdS/CFT

Fri, Sep 20, 2013, 1:30 pm to 2:30 pm
"AdS/CFT is a duality relating the degrees of freedom in a D dimensional bulk gravity theory to a (D-1) dimensional theory living on the boundary.

Hamilton Colloquium Series - Dr. Justin Kasper, University of Michigan; Smithsonian Astrophysical Observatory: "Sending a spacecraft to the Sun"

Thu, Sep 19, 2013, 4:30 pm to 5:30 pm

For centuries solar eclipses have provided brief glimpses of the solar corona, a remarkably structured atmosphere that surrounds the Sun and spreads into the solar system. Today, the Sun and the corona are tracked continuously by observatories on Earth and in space.

High Energy Theory Seminar - Edward Witten, IAS - "More on superstring perturbation theory"

Special Seminar - Gene-Wei Li (UCSF)

Mon, Sep 16, 2013, 12:00 pm to 1:00 pm
"Principles underlying cellular protein production"
Audience: LSI, MOL, Biophysics.

Informal HET Seminar - IAS - Boaz Keren-Zur, Ecole Polytechnique Federale de Lausanne, CH -The Local Callan-Symanzik Equation: Structure & Application

Wed, Sep 11, 2013, 1:30 pm to 2:30 pm
The local Callan-Symanzik equation describes the response of a quantum field theory to local scale transformations in the presence of background sources. The consistency conditions associated with this anomalous equation can be used to derive powerful constraints on RG flows.

Condensed Matter Seminar, Hong Ding, Institute of Physics, Chinese Academy of Sciences, "Probing iron-based superconductivity by photoelectrons"

Mon, Sep 9, 2013, 1:15 pm to 2:30 pm
Angle-resolved photoemission spectroscopy (ARPES) has been used extensively in studying electronic structure and superconducting gap of the iron-based superconductors (IBSCs). In this talk, I will present our ARPES results on the IBSCs, mainly focus on high-resolution measurements of the superconducting gap of many different IBSCs.

Condensed Matter Seminar, Xi Dai, "Topological phases in mix valence compounds"

Fri, Aug 30, 2013, 2:00 pm to 4:00 pm
In this talk, I will propose that the mix valence phenomena in some of the rare earth compounds will naturally lead to non-trivial topology in band structure.One of the typical example is SmB6, where the intermediate valence of Sm generates band inversion at the X point and the non-trivial Z2 index. Other than SmB6, YbB6 and YbB12 are both mix...

Special Seminar:Solving the Relativistic Inverse Stellar Structure Problem - Lee Lindblom, Theoretical Astrophysics, Caltech

Wed, Aug 14, 2013, 2:00 pm to 3:30 pm
Abstract: The inverse stellar structure problem determines the equation of state of the stellar matter from a knowledge of the stars' observable macroscopic properties, like their masses and radii. This seminar will discuss different approaches to solving this problem, including some new results based on spectral methods.
