Astronomy seminar: "The Hercules Stream: stars on Trojan orbits visiting the solar vicinity"
Elena D’Onghia (University of Wisconsin-Madison)
The origin of the stars with coherent velocities discovered in the solar neighborhood remains uncertain, but their dynamics and evolution are key to understanding the dynamics of the Galactic stellar disk and…
Special Seminar: "This Is Not A Diversity Talk"
John Asher Johnson, Harvard University
The American discourse on the various disparities present in society generally, and academia specifically, focuses primarily on observations of the state of a given situation---e.g. a lack of diversity---…
High Energy Theory seminar: "Direct Detection of sub-GeV Dark Matter: A New Frontier"
Rouven Essig, Stony Brook University
Dark matter makes up 85% of the matter in our Universe, but we have yet to learn its identity. While most experimental searches focus on Weakly Interacting Massive Particles (WIMPs) with masses above the proton (…
Condensed Matter seminar: "Fracton phase of matter: Lattice models, gauge theories and realizations"
Yizhi You, Princeton University
Fracton phase of matter shares many features of topological order, including long-range entangled ground states and non-trivial braiding statistics. At the same time, fracton phase contains subextensive ground-state…
Eli Burstein Lecture in Materials Science: "Designing Superconductivity: Using nanostructures to manipulate interactions in a complex system"
Nadya Mason, University of Illinois at Urbana-Champaign
One of the most fundamental scientific questions is how the macroscopic properties of matter emerge from complex interactions of microscopic constituents. In this talk, I will discuss a “bottom-up” approach to…
Department Colloquium: Progress Toward a Solution of the “Supernova Problem”
Anthony Mezzacappa, University of Tennessee
The death of massive stars in core collapse supernova explosions are directly or indirectly responsible for the lion’s share of the elements in the periodic table, give birth to neutron stars and stellar mass black…
Experimental Particle Physics Seminar: "Jinping Neutrino Experiment"
Shaomin Chen, Tsinghua University
