HET Seminar: Comments on wormholes and factorization
Philip Saad (IAS)
In AdS/CFT partition functions of decoupled copies of the CFT factorize. In bulk computations of such quantities contributions from spacetime wormholes which link separate asymptotic boundaries threaten…
Astronomy and Astrophysics Seminar: A Dynamical Synthesis of Planetary Systems
Malena Rice (Yale)
Dynamics provides a powerful tool to unify the various components of a planetary system. By studying the interactions between these components, it is possible to unveil a system’s evolutionary history and…
Condensed and Living Matter Seminar: "Life in a Tight Spot: How Bacteria Swim, Disperse, and Grow in Crowded Spaces"
Sujit Datta, Princeton University
Bacterial motility and growth play central roles in agriculture, the environment, and medicine. While bacterial behavior is typically studied in bulk liquid or on flat surfaces, many bacterial habitats—e.…
Physics and Astronomy Colloquium: "The synergy of biophysics and active materials" *POSTPONED*
Arnold Matthijssen (University of Pennsylvania)
Understanding the physics of living systems allows us to design new materials that are active and adaptive, akin to cells and tissues. Conversely, these active matter systems can reveal fundamental…
Condensed and Living Matter Seminar: "Pattern formation in biological systems via mechanical instabilities and phase separation"
Andrej Kosmrlj, Princeton University
Pattern formation is ubiquitous in biological systems. While pattern formations are often associated with Turing-like reaction-diffusion systems, biology also exploits many other mechanisms such as…
Thesis Defense: “Identifying Electrons and Searching for Electroweak R-Parity Violating Supersymmetry at ATLAS"
Lucas Flores (University of Pennsylvania)

High Energy Theory Seminar: (g-2)_\mu from lattice QCD and experiments: 4.2 sigma?
Zoltán Fodor (Wuppertal University, Pennsylvania State University, Inst. for Theoretical Physics ELTE Eötvös, and Jülich Supercomputing Centre)
Twenty years ago, in an experiment at Brookhaven National Laboratory, physicists detected what seemed to be a discrepancy between measurements of the muon’s magnetic moment and theoretical calculations of…
Astronomy Seminar: "The Peril and Promise of Three-Dimensional Planets"
Emily Rauscher (University of Michigan)
Much to the consternation of spherical cows everywhere, planets are three-dimensional objects. As we try to measure properties of their atmospheres, it may be inappropriate to pretend…
Mathematical Biology seminar: "Inductive Bias of Neural Networks"
Cengiz Pehlevan (Harvard University)
: Predicting a previously unseen example from training examples is unsolvable without additional assumptions about the nature of the task at hand. A learner’s performance depends…
