Condensed and Living Matter Seminar: "Non reciprocal phase transitions"
Vincenzo Vitelli, University of Chicago
The interaction between a peregrine falcon and a dove is visibly non-reciprocal. What happens to the well established framework of phase transitions in non-reciprocal systems far from equilibrium?…
Astronomy and Astrophysics Seminar: An Update on the Progress of EDGES
Steven Murray (Arizona State)
EDGES reported the first evidence of star formation in the high-redshift Universe (z~18) in 2018 (Bowman et al, 2018; hereafter B18). The extraordinary depth and flattened profile of the reported…
Thesis Defense: “Neutron Cross Section Measurement in the ProtoDUNE Single-Phase Experiment"
David Rivera (University of Pennsylvania)
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 …
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 …
Thesis Defense: “Identifying Electrons and Searching for Electroweak R-Parity Violating Supersymmetry at ATLAS"
