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 future…
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 spectral…
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,…

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 understood…
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…
Condensed and Living Matter Seminar: Title: "Understanding Glass Transition through Interfacial Properties"
Zahra Fakhraai (University of Pennsylvania)
The dramatic slow-down of the dynamics and viscosity of a liquid upon super-cooling without a significant structural signature, has been the topic of intense theoretical debate. Growing local correlations…
