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 amount to…
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…
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…
Astronomy and Astrophysics Seminar: Seeking solutions for the Hubble tension
Meng-Xiang Lin (Chicago)
Although the $\Lambda$CDM model has been remarkably successful in explaining a wide range of observational data, the model does not reconcile distance-redshift measurements when anchored at low redshift…
Condensed and Living Matter Seminar: "Quantum optics meets correlated electrons"
Mohammad Hafezi, University of Maryland
One of the key challenges in the development of quantum technologies is the control of light-matter interaction at the quantum level where individual excitations matter. During the past couple of decades…
From Foundations to Frontiers
Chinese American Contributions to the Fabric of America
Moderator: Prof. Andrea Liu
A special upcoming presentation and panel discussion for all members of the Penn community will be held virtually on October 19 at 4pm, featuring three members of the Penn faculty and the Committee…
