### Particle Physics Seminar, Matthew Dolan, SLAC, "Measuring the Higgs Self-Coupling at the LHC”

Fri, Dec 19, 2014, 4:00 pm to 5:30 pm

The measurement of the Higgs trilinear self-coupling is an important part of the LHC Higgs program at 14 TeV, which directly interrogates the mechanism of electroweak symmetry breaking in the Standard Model.

### Particle Physics Seminar, Stefania Gori, Perimeter, "Illuminating Dark Photons with High-Energy Colliders"

Fri, Dec 12, 2014, 4:00 pm to 5:00 pm

The LHC and future high-energy colliders offer a unique sensitivity to dark photons (ZD), the mediators of a broken dark U(1) gauge theory that kinetically mixes with the Standard Model hypercharge.

### High Energy Theory Seminar - Mikhail Isachenkov, DESY Hamburg - "Chiral Ring of Strange Metals"

Fri, Dec 12, 2014, 1:45 pm to 2:45 pm

A candidate description for a strange metal phase in 1+1 dimensions,
namely a model of strongly-coupled fermions in the adjoint representation of
SU(N) is considered. It is known that such models at high densities flow
to IR WZNW theories having an emergent
(2,2) supersymmetry. I describe the chiral ring of such
theories and discuss its large N...

### Special Condensed Matter Seminar, Donna Sheng, Cal State U., "Chiral spin liquid and quantum phase diagram for extended Kagome Heisenberg model”

Wed, Dec 10, 2014, 1:30 pm to 2:30 pm

The kagome spin-1/2 model with dominant nearest neighboring (J1) antiferromagnetic coupling

### Math Physics Seminar, Ivan Corwin, Columbia, "Stochastic higher spin vertex models on the line"

Tue, Dec 9, 2014, 4:30 pm to 6:00 pm

We show how transfer matrices of higher spin vertex models (generalizing the six-vertex model) can be conjugated into stochastic matrices describing interacting particle systems. Bethe ansatz produces eigenfunctions and we prove their completeness on the line.

### High Energy Theory Seminar- IAS - Frederik Denef, Columbia University, TBA

Mon, Dec 8, 2014, 2:30 pm to 3:30 pm

### Condensed Matter Seminar, Nicolas Regnault, Princeton University,"Matrix Product States and the Fractional Quantum Hall Effect"

Mon, Dec 8, 2014, 1:15 pm to 2:30 pm

: The understanding and simulation of quantum many-body states in one space dimension has experienced revolutionary progress with the advent of the density matrix renormalization group. In modern language, this method can be viewed as a variational optimization over the set of matrix product states (MPS).

### Particle Physics Seminar, Kiel Howe, Stanford, "Maximally Natural Supersymmetry and its Natural New Signatures"

Fri, Dec 5, 2014, 4:00 pm to 5:30 pm

Supersymmetric models with SUSY breaking by boundary conditions in a flat TeV-scale extra dimension avoid many of the problems of conventional MSSM-like models. A natural spectrum is easily realized by locality in the TeV sized direction, and the electroweak scale remains completely natural with stops and other superpartners above current LHC...

### High Energy Theory Seminar- IAS - Matthew Bullimore, IAS - “TBA”

Fri, Dec 5, 2014, 1:45 pm to 3:00 pm

### Gravity Group Lunch Seminar, Aurelien Fraisse, "Planck 2014 Results: Highlights & Outlook"

Fri, Dec 5, 2014, 12:00 pm to 1:30 pm

Following the Planck conference currently underway in Ferrara, Italy, I will present the main results from the Planck 2014 paper and data release scheduled for December 22nd.

### Hamilton Colloquium Series - Yifang Wang, Institute of High Energy Physics (Beijing): "Daya Bay neutrino experiment and the future"

Thu, Dec 4, 2014, 4:30 pm to 6:00 pm

Recently reactor neutrino experiments have made important contributions to the neutrino oscillation. I will introduce the Daya Bay experiment which observed for the first time the neutrino mixing angle θ13 with a statistical significance of 5.2 σ. The concept of the experiment, the detector construction and data analysis will be described.

### Shreyas Gokhale - Indian Institute of Science

Thu, Dec 4, 2014, 2:00 pm to Tue, Dec 2, 2014, 3:55 pm

### Using colloids to probe the physics of atomic systems:From the deformation of crystals to the formation of glasses - Shreyas Gokhale

Thu, Dec 4, 2014, 2:00 pm to 3:30 pm

Over the last fifteen years or so, suspensions of micron-sized colloidal particles have emerged as promising model systems to explore diverse atomistic phenomena ranging from dislocation dynamics in crystals to shear transformation zones in glasses.

### Informal High Energy Theory Seminar- Yifang Wang, Institute of HEP, Chinese Academy of Sciences - “Future Circular Colliders”

### High Energy Theory Seminar- Misha Smolkin, U. of CA, Berkeley - "Entanglement in Quantum Field Theory"

Tue, Dec 2, 2014, 2:30 pm to 3:30 pm

The first law of entanglement have received a considerable attention during last year. In my talk I will focus on its applications in the context of QFT and argue that certain calculations can be extended beyond the range of applicability of the first law. A number of simple examples will be presented.

### High Energy Theory Seminar- Clay Cordova, Harvard, "Deformations of Superconformal Field Theories"

Mon, Dec 1, 2014, 2:30 pm to 3:30 pm

Relevant, and marginal deformations play a crucial role in studying conformal field theories. In this talk I will classify such deformations for supersymmetric conformal field theories.

I will present recent results on the computation of finite N corrections in supergravity in the context of AdS2/CFT1 and AdS4/ABJM holography.
