High Energy Theory Seminar: Cohomology/K-theory of Lie groups and matter representations
Mboyo Esole (Northeastern University)
It was recently observed that the matter representations in F-theory compactifications overwhelmingly correspond to characteristic representations of Dynkin embedding index one. I will explain how this…
Physics and Astronomy Colloquium: "Uncovering New Transport Regimes and Light-Induced Phases in Quantum Materials "
Margaret Murnane (University of Colorado – Boulder)
High harmonic generation (HHG) is a unique quantum light source with fundamentally new capabilities, by up-converting femtosecond lasers to very short wavelengths. This produces fully spatially and…
Mathematical Biology seminar: "Cancer cells and their epithelial neighbors"
Katrina Podsypanina (Institut des Hautes Études Scientifiques [IHES])
I am a cancer researcher working on a framework for a new mathematical model of metastasis…
Thesis Defense: “Characterizing the Outer Solar System with the Dark Energy Survey"
Pedro Henrique Bernardinelli (University of Pennsylvania)
High Energy Theory Seminar: The KLT double-copy bootstrap
Henriette Elvang (University of Michigan)
The KLT (Kawai, Lewellen, Tye) formula famously maps a product of open string tree amplitudes to closed string tree amplitudes via a kinematic "KLT kernel" that depends on Mandelstam variables and alpha…
High Energy Experiment Seminar: Evidence of the four-top-quark production at the LHC
Nedaa Alexandra Asbah (Harvard)
Abstract: A summary of the latest results on the evidence of the four-top-quark production using proton-proton collision data at a centre of-mass…
Astronomy Seminar: How to Find an Earth
Megan Bedell (Flatiron)
The detection of an Earth twin (an Earth-mass planet orbiting a Sun-like star within the habitable zone) has recently become feasible for the first time thanks to advances in observational…
High Energy Theory Seminar: Classifying boundary conditions in JT gravity
Jorrit Kruthoff (Stanford)
We will discuss various boundary conditions in JT gravity and their implications in both the classical and quantum theory. Our focus will primarily be on fixing the metric and extrinsic curvature on the…
