Physics 128
Speaker: Daniel Scolnic (University of Chicago)
"Cosmological tension, gravitational waves, and how big will the universe be when it grows up" - The next decade will be the golden age of cosmology with transients. In this talk, I will present new analyses of Type Ia Supernovae that mark the most precise measurement of dark energy to date. I will... Read More »

Physics 128
Speaker: David Rubin (Space Telescope Science Institute)
"From Supernovae to Dark Energy: Current Results and a Recipe for Cosmological Progress" - Twenty years ago, cosmologists discovered that the expansion of the universe is accelerating. This discovery has challenged our understanding of the universe, revealing either an unknown additional component... Read More »

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 »
Wednesday, February 14, 2018 - 4:30pm
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 »
Tuesday, February 13, 2018 - 4:00pm
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 »
Tuesday, February 13, 2018 - 3:30pm
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 »
Tuesday, February 6, 2018 - 3:30pm
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 »
Thursday, January 25, 2018 - 3:00pm
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 »
