Dissertation Defense: "Two-point Statistics for Testing Models of Cosmic Structure"
Yuedong Fang (U of Penn)
Condensed Matter Seminar: "Controlling Strong Light Matter Coupling with Photonic Crystals"
Hui Deng (University of Michigan)
Microcavity exciton-polaritons provide a unique photonic platform that manifests non-equilibrium quantum orders. It combines strong nonlinearity and rich many-body physics of matter with robust coherence and ready…
Astro Seminar: "The Milky Way's Dust in Three Dimensions"
Edward Schlafly (Lawrence Berkeley National Laboratory)
Most observations of the Milky Way's gas and dust are limited to two dimensions; their angular distribution is precisely measured, but their distribution in distance is much more uncertain. Large surveys of…
Elon Musk Public Lecture: "Will Evolution and Information Theory Provide the Fundamentals of Physics?"
Sylvester James Gates, Jr. (Brown)
Join us for an evening with theoretical physicist Sylvester James Gates, Jr., as he talks about how the mathematical and theoretical aspects of his physics research have traversed concept spaces from equations to…
Math/Phys Joint Seminar: "Progress Toward A Mathematically Rigorous Space-time SUSY Representation Theory"
Sylvester James Gates, Jr. (Brown University)
While a fundamental representation theory for compact Lie algebras was settled by the work of Cartan (i.e. weights and roots), no analogous conceptual structure exists for space-time supersymmetry algebras. …
High Energy Theory Seminar: "Bit Threads in Space and Time"
Matt Headrick (Brandeis University)
Bit threads are a reformulation of the Ryu-Takayanagi holographic entanglement entropy formula that offer several conceptual advantages over the standard minimal-surface formulation. After briefly…
Condensed Matter Seminar: "Soft matter physics in the gut"
Sujit S. Datta (Princeton University)
The gut governs digestion and nutrient absorption, is a promising target for drug delivery, and teems with micro-organisms that can have remarkably strong effects on host health. Despite its importance, however,…
High Energy Theory Seminar: "Naturally Stabilizing the Weak Scale without Partners"
Devin Walker (Dartmouth College)
We generalize and adapt Veltman's condition to create a framework which naturally addresses the little hierarchy problem. The resulting class of models is economical and ensures a minimum amount of fine-tuning…
Condensed Matter Seminar: "Mechanical Cell Biology of Microbes"
Enrique Rojas (Stanford University)
Research in microbial physiology has traditionally focused on understanding biochemical pathways and, more recently, on elucidating the surprisingly complex structure of microbial cytoplasm. On the other hand,…
