HET Seminar | Senthil Todadri, Massachusetts Institute of Technology | “Symmetry Enriched Emergent U(1) Gauge Theories"

Mon, Nov 14, 2016, 2:30 pm to 3:30 pm
Phases of quantum many particle systems can have low energy effective field theoretic descriptions in terms of gauge theories in their deconfined phase.

CM Video Seminar, Brian Swingle, Harvard, "Measuring Quantum Information Scrambling"

Mon, Nov 14, 2016, 1:15 pm to 2:30 pm
Out-of-time-order correlation functions are of theoretical interest for diagnosing the scrambling of quantum information in black holes and strongly interacting quantum systems generally. I will describe a general protocol for measuring them which requires an echo-type sequence in which the sign of a many-body Hamiltonian is reversed.

Special CM Seminar, Dominik Zumbuhl, U. of Basel, "Edge state spectroscopy with a GaAs quantum wire"

Light at the start of the tunnel: the LHC program comes into focus - Robert McPherson - University of Victoria

A Particle Physics Experiment in Space: The Results from the first five years of AMS on the Space Station - Samuel Ting - Massachusetts Institute of T

HET Seminar | Thomas Mertens, Princeton University | “An Investigation of AdS2 Backreaction and Holography"

Fri, Nov 11, 2016, 1:45 pm to 3:00 pm
In this talk, I will discuss the Jackiw-Teitelboim model in 2d dilaton gravity in a holographic context. After deriving the boundary time reparametrization equation and the holographic stress tensor, I will demonstrate that these can be obtained from an effective boundary model.

Gravity Group Seminar, Anna Ijjas, Paul Steinhardt

Fri, Nov 11, 2016, 12:00 pm to 1:30 pm

TITLE Early-Universe Boot-camp Part III: The truth about bounces ABSTRACT This will be the third part of the early-universe boot-camp in which we will focus on cosmologies that replace a big bang with a big bounce.

HEP Seminar-Jakob Salfeld-CERN-TBA

Fri, Nov 11, 2016, 11:00 am to Mon, Oct 31, 2016, 12:00 pm


Special HEP Seminar-Jakob Salfeld-Nebgen-"Precision measurements at the LHC: Luminosity and W/Z cross section measurements with the CMS"

Fri, Nov 11, 2016, 11:00 am to Thu, Nov 3, 2016, 12:30 pm
With the start of Run-2 of the LHC in 2015 physical processes predicted by the Standard Model are now being tested at 13 TeV centre-of-mass energy. In particular, the cross section of W and Z bosons in proton-proton collisions can be measured with high accuracy.

Hamilton Colloquium Series: Neal Weiner, NYU; "The Dark Ages of Dark Matter"

Thu, Nov 10, 2016, 4:00 pm to 5:30 pm

The search for dark matter is among the most challenging in particle physics, because even the question of how to look for it relies on an idea of what it is. The past decade has brought tremendous new data constraining the most popular scenario - the Weakly Interacting Massive Particle or WIMP.

Special Pheno & Vino Seminar, Nima Arkani-Hamed, IAS, "A Nnew, Cosmological Solution of the Hierarchy Problem"

Thu, Nov 10, 2016, 1:00 pm to 2:30 pm
In this talk I will describe a new solution to the hierarchy problem, "Nnaturalness". Introducing a large N copies of the Standard Model with varying values of the Higgs mass parameter allows the lightest of these sectors to have a weak scale parametrically lighter than the cutoff.

HEP Seminar-Sinziana Paduroiu-UNIGE-"Warm Dark Matter Cosmologies: in theory and simulations"

Wed, Nov 9, 2016, 3:00 pm to 4:00 pm
Warm dark matter models are a viable alternative to the cold dark matter models challenged by many recent observations (e.g. dwarf galaxies, pure-disk galaxies, matter distribution in voids) and by the narrowed detection limits.

Pheno & Vino Seminar, Gordon Krnjaic, Perimeter, "Can the baryon asymmetry arise from initial conditions?"

Tue, Nov 8, 2016, 4:00 pm to 5:30 pm
In this talk, I'll quantify the challenge of explaining the baryon asymmetry using initial conditions in a universe that undergoes inflation. Contrary to lore, such an explanation is possible if net B−L number is stored in a light bosonic field with hyper-Planckian initial displacement and a delicately field velocity prior to inflation.

Condensed Matter Seminar, Erik Nielsen, Sandia National Laboratories, "Silicon qubit device modeling and qubit characterization"

Tue, Nov 8, 2016, 11:00 am to 12:00 pm
Research in quantum computing is a still-growing field, fueled by interest in both it’s powerful applications and connection to fundamental science.  Qubits, the building blocks of future quantum computers, must both manipulate and protect the quantum information they hold – a task fraught with challenges.
