Physics 128
Speaker: Elinor Medezinski (Princeton)
"Weighing Galaxy Clusters with Weak Lensing" - The most fundamental question in observational cosmology today is what is the nature of dark energy and dark matter. As the most massive gravitationally bound bodies in the Universe, clusters of galaxies serve as beacons to the growth of structure over... Read More »

Physics 128
Speaker: Chihway Chang, The University of Chicago
"Cosmic Surveys in the Next Decade: Mapping the Landscape of the Universe" - Cosmology in the next decade will be driven by data. Exploiting the information one can extract from the ongoing and upcoming large surveys will give us the power to stress-test the LCDM model with unprecedented precision... Read More »

Hudson Hall 125
Speaker: Professor Eugenia Kumacheva & Duke Faculty
The purpose of the Duke Soft Matter Seminar Series is to bring together the diverse Soft Matter investigators at Duke in order to create a large, supportive community and encourage collaboration. Short updates from investigators in Arts & Sciences, Engineering, and the School of Medicine will... Read More »

Physics 298
Speaker: Nate Harshman (American University)
Motivated by applications to ultracold atoms in optical traps, I will present some examples of quantum few-body models with hard-core interactions. Despite the simplicity of the interaction, these models can have surprising dynamical properties, like superintegrability or fractional statistics. In... Read More »

Physics 298
Speaker: Claudia Ratti (University of Houston)
Quantum Chromodynamics (QCD) is the fundamental theory describing the interactions between the ultimate building blocks of matter, namely quarks and gluons. At temperatures as high as trillions of degrees Kelvin and zero net baryon density, first principle Lattice QCD calculations have shown that a... Read More »

Physics 128
Speaker: Nancy M. Haegel (National Renewable Energy Laboratory)
It is well understood and commonly cited that the solar energy resource significantly exceeds the world's total energy consumption. However, despite dramatic advances in deployment and cost reduction, the vision of PV providing a significant fraction of global electricity generation-and ultimately... Read More »

Physics 278
Speaker: Daniel Whiteson, University of California, Irvine
Recent advances in artificial intelligence offer opportunities to disrupt the traditional techniques for data analysis in high energy physics. I will describe the new machine learning techniques, explain why they are particularly well suited for particle physics, and present selected results that... Read More »
Wednesday, January 17, 2018 - 4:30pm
Physics 298
Speaker: Art Champagne (UNC and Duke Physics)
"Abundance Anomalies in Globular Clusters: Does the Fault Lie in the Stars?" - Globular clusters are the oldest structures to form in the galaxy and thus their ages provide a wealth of information about the evolution of the Milky Way. These ages assume that we understand stellar evolution and the... Read More »

Physics 298
Speaker: Jacquelyn Noronha-Hostler
The QCD equation of state at zero baryon chemical potential is the only element of the standard dynamical framework to describe heavy ion collisions that can be directly determined from first principles. Continuum extrapolated lattice QCD equations of state have been computed using 2+1 quark... Read More »

Physics 298
Speaker: Sho Yaida (Duke University)
Glassy materials are omnipresent in everyday life from windows to plastics to piles of sand. Yet our understanding of both their (equilibrium) liquid and (out-of-equilibrium) solid phases lags far behind that of crystalline counterparts. Recent advances are rapidly changing the ways in which we... Read More »
