Special Seminar

Symmetry constraints in quantum materials: making the most of seeing nothing - Michael Zaletel, UCSB

Tue, Nov 10, 2015, 1:00 pm to 2:00 pm
A fundamental property of any material is the electron filling, i.e., the number of electrons per unit cell. Within band theory, materials at odd filling must be metals, while those at even filling can be insulators.

Special seminar - Berthold Jäck, Max-Planck Institute, Stuttgardt, "The Josephson effect as a local probe for superconductivity"

Fri, Oct 23, 2015, 1:00 pm to 2:00 pm
Berthold Jäck, Matthias Eltschka, Markus Etzkorn, Christian R. Ast, and Klaus Kern

Gravitational-wave and electromagnetic signatures of binary neutron star mergers - Kenta Hotokezaka - The Racah Institute of Physics

Tue, Sep 29, 2015, 1:00 pm to 2:00 pm
A binary neutron star merger produces gravitational-waves and also electromagnetic transients in multi-wavelenghts. First part of the talk, I will focus on the current status of gravitational waveform modeling for binary neutron star mergers. Using a numerical relativity simulation,

Special Cosmology Seminar, Gayoung Chon "Cosmological studies with the REFLEX cluster survey"

Tue, Sep 1, 2015, 2:00 pm to 3:30 pm
We use a large, statistically well characterised X-ray flux-limited sample of galaxy clusters in the southern hemisphere to study the large-scale structure of the Universe and to probe cosmology out to redshifts of ~ 0.4. We study X-ray superclusters constructed with a strict definition such that

*Special Seminar* Lucas Parker - Final Public Oral Examination (FPO)

Fri, Aug 7, 2015, 3:30 pm to 5:00 pm
The final public oral examination of Lucas Parker will take place on Friday, August 7, 2015 at 3:30 pm in Room 202 Jadwin Hall. The examining committee will consist of Professors Page, Pufu and Jones. Any other members of the University wishing to attend the examination may do so.

Holographic Conductivity and Stokes Flows on Black Hole Horizons - Jerome Gauntlett

Wed, Aug 5, 2015, 2:15 pm to 4:00 pm
The AdS/CFT correspondence provides a powerful framework for studying strongly coupled field theories using gravitational techniques. Motivated by possible applications to condensed matter systems many novel classes of black hole solutions have been discovered over the past few years.

Einstein's equations in a (3+1)-split: the gravitoelectric Gauss law and the gravitomagnetic Ampere law

Special Seminar - Reunions - Physics Demonstrations: What could go Wrong? - Prof. Steve Gubser

Special seminar – Nayoon Woo, University of Chicago, "Interplay of disorder and geometrical frustration in doped Gadolinium Gallium Garnet"

Fri, Apr 17, 2015, 1:00 pm to 2:00 pm
Antiferromagnets are characterized by interactions between spins that favor configurations with nearest neighbors pointing anti-parallel. In some systems, the topology of the spins produces a situation where spins cannot find an orientation that fully satisfies all of the interaction constraints. This is known as geometrical frustration.

Special Seminar - "Hostile and Benevolent Sexism: A Discussion for Women and Men in STEM." - Susan Fiske - Princeton University

Special Seminar - " Cosmology from the Planck satellite and beyond" - Joanna Dunkley

Mon, Feb 9, 2015, 3:30 pm to 4:30 pm
The Cosmic Microwave Background continues to provide us with a wealth of information about the universe. I will show new results from the complete Planck satellite mission, which mapped the microwave anisotropy in both temperature and polarization from 2009-13, and describe other recent progress in the field.

Special Seminar - Magnetic resonance with Single-Nuclear-Spin Sensitivity - Alex Sushkov, Harvard University

Wed, Feb 4, 2015, 2:00 pm to 3:00 pm
Our method of nanoscale magnetic sensing and imaging makes use of nitrogen-vacancy (NV) color centers a few nanometers below the surface of a diamond crystal. Using individual NV centers, we perform NMR experiments on single protein molecules, labeled with carbon-13 and deuterium isotopes.

Special Seminar -Fingers, toes and tongues: the anatomy of interfacial instabilities in viscous fluids - Irmgard Bischofberger, University of Chicago

Mon, Feb 2, 2015, 2:30 pm to 3:30 pm
The invasion of one fluid into another of higher viscosity is unstable and produces complex patterns in a quasi-two dimensional geometry. This viscous-fingering instability,a bedrock of our understanding of pattern formation, has been characterized by a mostunstable wavelength that sets the characteristic width of the fingers.

Special Seminar -Chris Martin-Johns Hopkins University-What did we find? Characterizing a new particle using 4l events from the CMS Experiment.

Thu, Jan 15, 2015, 2:00 pm to 3:00 pm
A new resonance decaying to a pair of vector bosons was discovered in 2012 by the ATLAS and CMS experiments at the LHC. In the wake of this discovery a rush of measurements was made to characterize this discovery. The four-lepton final state has been instrumental in both the discovery

Special Seminar - Higgs boson physics at ATLAS from the WW perspective - Corrinne Mills

Wed, Jan 14, 2015, 2:00 pm to 3:00 pm
Abstract: Testing the compatibility of the Higgs boson with mH ~ 125 GeV with the Standard Model predictions is a top priority of the LHC experimental program. Analysis of the WW decay mode of the Higgs boson at ATLAS provides the best single-channel signal strength measurement from Run 1 of the LHC.

Special Seminar - The MAJORANA Low-Background Broad Energy Germanium Detector - Graham Giovanetti

Tue, Jan 13, 2015, 2:00 pm to 3:00 pm
The MAJORANA DEMONSTRATOR is an array of natural and enriched high purity germanium detectors that will search for the neutrinoless double-beta decay of 76-Ge. As part of the MAJORANA research and development efforts, we have deployed a modified, low-background broad energy germanium detector at the Kimballton Underground Research Facility.

High-resolution imaging of ordering in Rydberg many-body systems - Peter Schauss

Tue, Jan 6, 2015, 2:00 pm to 3:00 pm
In this talk I will present results on the preparation and high-resolution imaging of Rydberg many-body systems and the observation of spontaneous emergence of self-organized ordering. In a first series of experiments we investigate the ordering in the post-selected high-excitation-density components of high-temperature many-body
