Thesis Defense: "Structure, Dynamics, and Elasticity in Amorphous Systems"
Sean Ridout, University of Pennsylvania
Physics and Astronomy Colloquium: "A case for integrating solar geoengineering into climate policy"
David Keith (Harvard University)
I will first review the science and technology of solar geoengineering, addressing the following Q’s: how effective could it be in reducing climate risks? What new risks does it entail? What is uncertain…
Thesis Defense: "Continuing the Search for Nothing: Invisible Higgs Boson Decays and High Luminosity Upgrades at the ATLAS Detector"
Benjamin Rosser, University of Pennsylvania
HET Seminar: An Introduction to the Lattice-Continuum Correspondence
Djordje Radicevic (Brandeis)
I will describe a simple and explicit way to construct continuum quantum field theories out of finite, nonperturbatively well defined lattice theories. This formalizes decades of intuition, leads to new…
Condensed and Living Matter Seminar: "Broken symmetries in living matter"
Nikta Fakhri, MIT
Active processes in living systems create a novel class of nonequilibrium matter composed of many interacting components that individually consume energy and collectively generate motion or…
Astronomy and Astrophysics Seminar: The next frontier in gravitational wave cosmology
Jose Maria Ezquiaga (Chicago)
Gravitational waves (GWs) are reshaping our understanding of the universe, and the more exciting discoveries are yet to come. In the next observing runs we will observe hundreds to thousands of events per…
HET Seminar: A Causal Modification of Quantum Mechanics
David E. Kaplan (JHU)
We present a modification of quantum mechanics in which a specific class of state-dependent term is added to the Schroedinger Equation. We show that this term produces non-trivial effects which…
Astronomy and Astrophysics Seminar: Cosmological Information in Forward Modeling of Biased Tracers
Giovanni Cabass (IAS).
I discuss how much information on cosmological parameters can be extracted from a perturbative bias model at the field level after marginalizing over initial conditions, compared with summary…
Condensed and Living Matter Seminar: "Twisting nodal superconductors"
Jed Pixley, Rutgers University
The realization of correlated insulators and superconductivity in twisted van der Waals heterostructures has brought forth twisting as a new control knob in condensed matter laboratories. In this talk we…
