Astronomy on Tap Triangle #11 Brad Barlow, High Point University JJ Hermes, UNC Chapel Hill "Slingshotting Stars Out of the Galaxy" Join us for another Astronomy on Tap Triangle, our North Carolina chapter of short, engaging talks about astronomy over … Read more
UNC-CH Physics and Astronomy PhD Defense Sean Hunt "Helium Burning of 22Ne: Targets, Detectors, and Initial Measurements" Half of all heavy elements are produced in stellar environments through the nucleosynthetic s-process. The s-process takes place in asymptotic giant branch stars … Read more
UNC-CH Physics and Astronomy PhD Defense Andrew L. Cooper "A Low-Energy Study of the 20Ne(proton,gamma)21Na Reaction with High-Current Proton Beams at LENA" The neon-sodium (NeNa) cycle is believed to play a pivotal role in explaining the oxygen-sodium abundance anticorrelation exhibited … Read more
UNC-CH Physics and Astronomy Colloquium Gökce Basar, University of Illinois, Chicago "Going with the flow: making the path integral more complex" The theory of strong interactions (Quantum Chromo Dynamics, or QCD), which describes how the constituents of protons and neutrons … Read more
UNC-CH Physics and Astronomy Chalk Talk Gökce Basar, University of Illinois, Chicago "Non-Perturbative approaches to strongly interacting systems" I will provide an overview of the outstanding problems, from my perspective, of the physics of strongly interacting systems, with an emphasis … Read more
UNC-CH Physics and Astronomy Colloquium Walter Pettus, University of Washington "Weighing a Ghost: The Quest to Measure the Neutrino Mass" The ghostly neutrinos remain the only fundamental fermions whose masses are unknown. Neutrino oscillation measurements definitively demonstrate neutrinos have mass, … Read more
UNC-CH Physics and Astronomy Chalk Talk Walter Pettus, University of Washington "Backwards is Better: Next-Generation Detectors for Nuclear Physics" The neutrino continues to conceal many of its fundamental properties, rebuffing the advances of modern physics. When our best isn’t good … Read more
UNC-CH Physics and Astronomy Colloquium Graham Giovanetti, Princeton University "Searching for dark matter with liquid argon" The DarkSide collaboration has undertaken a staged program using argon time projection chambers (TPCs) to search for dark matter. I will introduce DarkSide-50, a … Read more
UNC-CH Physics and Astronomy Chalk Talk Graham Giovanetti, Princeton University "Development of low-background detectors for future rare-event searches" Physics beyond the Standard Model may be accessible to novel, ultra low-background detectors that push the frontiers of experimental sensitivity. Two such … Read more
UNC-CH Physics and Astronomy PhD Defense Andrew Loheac “Computational techniques to address the sign problem in non-relativistic quantum thermodynamics” Understanding quantum many-body physics is crucial to physical systems throughout condensed matter, high-energy, and nuclear physics, as well as the development … Read more
