Special High Energy Theory seminar
Laura Johnson (Case Western University)
High Energy Theory seminar
Joshua Ruderman (New York University)
Mathematical Biology seminar: “Water Dynamics in Cells and Tissues"
Sean Sun (Johns Hopkins University)
The mammalian cell surface is highly permeable to water. The cell can also actively control the water flux across the cell surface by pumping solutes (mostly ions), and thereby controlling the cell water…
Special High Energy Theory seminar: "Conformal Inversion of Extremal Black Holes, and Aretakis and Newman-Penrose Charges"
Chris Pope (Texas A&M University)
The extremal Reissener-Nordstrom metric is invariant under an inversion of the radial coordinates, combined with a conformal rescaling. This implies that conserved Aretakis charges, defined on the…
Physics and Astronomy Colloquium: "Finding Other Earths – New Frontiers in Exoplanet Science with Next-Generation Doppler Spectrometers"
Cullen Blake (University of Pennsylvania)
The Doppler technique is a key tool for discovering and characterizing planets orbiting other stars. By measuring periodic shifts in stellar…
Knowledge by the Slice lunchtime series: "Finding the First Stars and Galaxies (by Looking Where They Aren’t"
James Aguirre (University of Pennsylvania)
Our current understanding of the universe starts with a Big Bang 13.7 billion years ago that created a simple,…
Joint High Energy Theory/Experiment seminar
Patrick Meade
Physics and Astronomy Colloquium: "Top Down Approach to Quantum Fields"
Jonathan Heckman (University of Pennsylvania)
Quantum Field Theory (QFT) is the common language of particle physicists, cosmologists, and condensed matter physicists. Even so, many fundamental aspects of QFT remain poorly…
High Energy Theory seminar: "Swampland distance conjecture and walls of marginal stability"
Markus Dierigl (University of Pennsylvania)
Advances in Biomedical Optics seminar series: "Wearable Bio-Inspired Imaging Systems for Image Guided Surgery"
Viktor Gruev (University of Illinois at Urbana Champaign)
Nature has served as an inspiration for novel, efficient and economic designs in architecture, engineering and science in general. In this talk, I will describe a bio-inspired sensory designs…
