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

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.

Physics Puzzles Your Parents Will Get Wrong In Spite Of A Princeton Degree. - Prof. Bob Austin

Particle Physics Seminar, Francesco D'Eramo, "Anomaly Mediation from Unbroken Supergravity"

Wed, Apr 16, 2014, 3:00 pm to 5:00 pm
In this talk I will show how the sparticle soft masses generated by anomaly mediation, proportional to the gravitino mass, should be associated to unbroken supersymmetry (SUSY). This counterintuitive result arises because the underlying symmetry structure of (broken) supergravity in flat space is in fact (unbroken) SUSY in anti-de Sitter space.

Special Seminar - A quantum computational perspective on quantum physics - Dorit Aharonov, Hebrew University

Fri, Apr 11, 2014, 2:45 pm to 3:45 pm
Quantum computation has taught us that quantum many body systems can be viewed from a computational perspective. This approach to studying quantum systems turns out to lead to a remarkably rich set of insights, ideas and directions to explore. I will try to give a taste of the main achievements in this vibrant fast growing area over the past...

Particle Physics, Yonit Hockberg, "The SIMP miracle"

Wed, Apr 9, 2014, 3:00 pm to 5:00 pm
We present a new paradigm for achieving thermal relic dark matter. The mechanism arises when a nearly secluded dark sector is thermalized with the Standard Model after reheating. The freezeout process is a number-changing 3 \to 2 annihilation of strongly-interacting-massive-particles (SIMPs) in the dark sector, and points to sub-GeV dark matter.

Quantum Sciences Seminar Series - Guido Burkard, University of Konstanz, Germany - "Spin Qubits in Carbon"

Wed, Apr 2, 2014, 1:00 pm to 2:00 pm

Graphene and carbon nanotubes have emerged as interesting new materials for electronics. But carbon is also a unique element for spintronics, and in particular for spin-based quantum information processing [1], because the low concentration of nuclear spins in natural carbon allows for long electron spin coherence times.

Special Seminar - Matthias Troyer, ETH, Zurich: "Interacting Anyons in Topological Quantum Liquids: Variations on the 'golden chain' "

Fri, Mar 28, 2014, 1:30 pm to 2:30 pm
We discuss generalizations of fermionic quantum lattice models using anyonic degrees of freedom. The simplest model for interacting anyons, the “golden chain” energetically favors neighboring localized anyons to fuse into the trivial channel, similar to the quantum Heisenberg model favoring neighboring spins to form spin singlets.

Special seminar - Hiroyuki Inoue, Weizmann Institute: "Collective Neutral Modes in Quantum Hall Regimes"

Fri, Mar 21, 2014, 11:00 am to 12:30 pm
The integer and fractional quantum Hall effects (IQHE and FQHE) are canonical examples of 2D topological phases. Being incompressible liquid in the bulk, available low-energy propagating excitations are only at the edge: gapless chiral edge channels. The excitations therein are electrons in the IQHEs and fractional quasiparticles in the FQHEs.

Special seminar - Yue Cao, University of Colorado: "Deciphering the Spin-Orbital Coupled Wavefunction"

Thu, Mar 20, 2014, 12:00 pm to 1:30 pm
Understanding the structure of the wavefunction is essential for depicting the surface states of a topological insulator.

Special seminar - Fereshte Ghahari, Columbia University, "Transport and Thermoelectric Studies of Correlated Phenomena in Graphene"

Fri, Mar 14, 2014, 1:30 pm to 2:30 pm
The observation of correlated electron physics in graphene is mostly limited by strong electron scattering that is caused by charge impurities.

Special Seminar - Physical forces shaping morphology - Karen Alim, Harvard

Wed, Mar 12, 2014, 2:00 pm to 3:00 pm
Physical forces can induce long-ranged interactions and thus propagate information on large scales. Especially during the development of an organism, coordination on large scales in short time is essential.

Quantum Sciences Seminar Series - Jérémie Viennot, ENS Paris, "Out of equilibrium charge dynamics in a cQED architecture"

Tue, Mar 11, 2014, 1:00 pm to 2:00 pm

In the context of circuit quantum electrodynamics, recent developments made it possible to build hybrid circuits [1], including many types of quantum dots. The versatility of these systems allows us to explore several directions, from quantum information engineering to many-body physics, all in a circuit QED architecture.

Special Seminar - "Fundamental Limits Governing Protein Folding and Function" - Milo Miaoyu Lin, Berkeley

Special Seminar - Quantum phase transitions in 2d metals: non-Fermi-liquid behavior and superconductivity, Max Metlitski, Kavil Institute, USCB

Tue, Feb 18, 2014, 9:30 am to 10:30 am
: A central question of modern condensed matter physics is how can our standard description of metals, the Landau Fermi-liquid theory, breakdown. In this light, quantum phase transitions associated with onset of order in metals have attracted much interest.

Special Seminar - The Dark Energy Survey early science and perspectives, Marcelle-Soare-Santos, Fermi Lab

Mon, Feb 17, 2014, 4:00 pm to 5:00 pm
The Dark Energy Survey (DES) Collaboration has started a 5000 square degree imaging survey of the southern galactic cap using a new 3 sq. deg., 520 Megapixel CCD camera, the Dark Energy Camera (DECam), mounted on the Blanco 4-meter telescope at the Cerro-Tololo Inter-American Observatory in Chile. DECam has achieved first-light in September 2012.

Special Seminar - Symmetry Protected Topological Phases: Prediction, Construction, and Classification - Xie Chen

Thu, Feb 6, 2014, 2:00 pm to 3:00 pm
Topological insulators, with their gapless conducting edges around a gapped insulating bulk, represent a new form of matter. While their topological nature is usually attributed to free electrons filling a topological band structure, it is highly desirable to understand whether similar topological phenomena exist more generally in interacting...
