  • **CANCELLED** Astro Seminar: "The Twisted Universe: The Cosmic Quest to Reveal Which End is Up"

    David Rittenhouse Laboratory, A4

    Brian Keating (UCSD)

    The cosmic microwave background (CMB) has spectacularly advanced our understanding of the origin, composition, and evolution of our universe. Yet there is still much to glean from this, the oldest light in the universe. Powerful telescopes are plying the skies in a quest to discover new physics. This talk concentrates on measurements by cutting-edge CMB telescopes which offer a glimpse into an exhilarating, and largely unexplored branch of astrophysics: the search for unique signatures in the polarization of the CMB.

  • Condensed Matter Seminar: "Mechanical Cell Biology of Microbes"

    David Rittenhouse Laboratory, A4

    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, the whether mechanical forces also play a role in controlling sub-cellular processes in microbes has been overlooked. I will highlight several novel paradigms by which microbes use mechanical (and electrical) factors as signals to control cell growth, division, and survival, and highlight how the remarkable mechanical properties of the cells are critical for these p

  • Condensed Matter Seminar: "Soft matter physics in the gut"

    David Rittenhouse Laboratory, A4

    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, little is known about how the structure and function of the gut are influenced by many of the soft materials that transit through it regularly.

  • Condensed Matter Seminar: "Controlling Strong Light Matter Coupling with Photonic Crystals"

    David Rittenhouse Laboratory, A4

    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 accessibility of light, allowing diverse quantum phenomena at high temperature, on a photonic chip. To go beyond 2D condensation physics, it becomes important to control the fundamental properties of polaritons without destroying the quantum orders.

  • Department Colloquium: "Discovering the Highest Energy Neutrinos Using a Radio Phased Array"

    David Rittenhouse Laboratory, A8

    Abigail Vieregg (University of Chicago) hosted by: Mark Devlin

    Ultra-high energy neutrino astronomy sits at the boundary between particle physics and astrophysics. The detection of high energy neutrinos is an important step toward understanding the most energetic cosmic accelerators and would enable tests of fundamental physics at energy scales that cannot easily be achieved on Earth.
