Physics 119
Speaker: Sidney Nagel (Univ of Chicago)
"Exploiting Disorder for Global Response: Independence of Bond-Level Contributions" - We are customarily taught to understand ordinary solids by considering perturbations about a perfect crystal. This approach becomes increasingly untenable as the amount of disorder in the solid increases; for a... Read More »

Physics 130
Speaker: Christoph Schmidt (Göttingen)
"Active Matter Builds Life" - Thermodynamic non-equilibrium is a defining feature of living systems on all levels of organization. Cells and tissues are built of "active matter", dynamic materials with built-in force generators. Such materials self-organize in biological systems into well-ordered... Read More »

Speaker: Yuriy Bomze
A penumbral lunar eclipse is a subtle phenomenon occurs when the Moon moves through the outer part of Earth's shadow. It is not as spectacular as a total or partial lunar eclipses and could be recognized as a slight shadow across the Moon. A couple of telescopes will be set on the deck in front of... Read More »

Raleigh, NC 
Speaker: David Kaplan (INT, Univ. of Washington)
Currently there does not exist an accepted way to nonperturbatively regulate chiral gauge theories, such as the Standard Model. A lattice formulation leads to mirror fermions that we do not see, and decoupling via a big mass would break the gauge symmetry. Past approaches for eliminating the mirror... Read More »

Physics 299
Speaker: Hao Zhang (TU Delft)
Note the unusual weekday! -- Majorana modes in hybrid superconductor-semiconductor nanowire devices can be probed via tunneling spectroscopy which shows a zero bias peak (ZBP) in differential conductance. However, alternative mechanisms such as disorder or formation of quantum dots can also give... Read More »

Physics 298
Speaker: Eduardo Novais (Universidade Federal do ABC, Brazil)
A fundamental challenge to quantum information processing is to protect information from the detrimental effects of the environment. A milestone in addressing this problem was the development of the theory of quantum error correction (QEC). In this work, we build upon previous studies in order to... Read More »
Tuesday, March 8, 2016 - 3:30pm
Chapel Hill, N.C.
Speaker: Heiko Hergert (Michigan State)
The reach of ab initio many-body techniques has increased tremendously in recent years, owing to new developments in many-body theory as well as advances in their numerical implementation. Coupled Cluster, Self-Consistent Green's Function, and In-Medium Similarity Renormalization Group (IM-SRG)... Read More »
Wednesday, March 2, 2016 - 3:30pm
Physics 130
Speaker: Warren S. Warren (Duke University)
"Revisiting Decades-Old Physics to Improve Modern Molecular Imaging" Molecular imaging-the use of chemical signatures to image function instead of merely structure-promises to enable a new generation of clinical modalities that can revolutionize both diagnosis and treatment. I will focus on two... Read More »
Tuesday, March 1, 2016 - 2:00pm
Physics 278
Speaker: Brian Tennyson, Yale University
Two-phase liquid noble element-based detectors are used in a variety of fundamental physics experiment applications. This seminar will focus on xenon-based detectors, specifically the Large Underground Xenon (LUX) experiment and the Particle Identification in Xenon at Yale (PIXeY) and Compton-... Read More »
Thursday, February 25, 2016 - 11:30am
Physics 298
Speaker: Adriana Moreo (University of Tennessee, ORNL)
The phase diagram of electron-doped pnictides as a function of temperature, electronic density, and isotropic quenched disorder strength obtained by means of computational techniques applied to a three-orbital (xz, yz, xy) spin-fermion model with lattice degrees of freedom will be presented. In... Read More »
