High Energy Seminar: Nonlinear Black Hole Ringdown

Macarena Lagos (Columbia University)
- David Rittenhouse Laboratory, 3C6

Gravitational waves (GWs) offer a unique observational window into the nature of gravity. In particular, the remnant black hole formed after the merger of two compact objects emits GWs with a…



Elon Musk Public Lecture: "The Many Worlds of Quantum Mechanics"

Sean Carroll (Johns Hopkins University)
- Arch Auditorium - Arch Building (Room 208), 3601 Locust Walk

One of the great intellectual achievements of the twentieth century was the theory of quantum mechanics, according to which observational results can only be predicted probabilistically rather than with…



Condensed Matter Seminar: Multi-gap topological physics: geometrical notions, physical phases and novel response

Robert-Jan Slager (University of Cambridge)
- David Rittenhouse Laboratory, A4

I will review recent work on multi-gap topological states. These phases are characterized by topological structures that cannot be captured by advances in more conventional symmetry-based…



Astrophysics seminar: The Red Universe UNCOVERed: Early Spectral results from the JWST Treasury Survey UNCOVER

Jenny Greene (Princeton University), https://crispygreene.wixsite.com/jenny
- DRL 4E19

From brown dwarfs to the first galaxies, JWST is giving us a new look at the Universe in the infrared. UNCOVER has just completed a deep spectroscopic survey in the Hubble Frontier Field Abell 2744. I will discuss…



High Energy Theory seminar: Gluon scattering in AdS from supersymmetric localization

Pietro Ferrero (SCGP)
- DRL 3C6

I will discuss some of the recent progress made in the computation of holographic correlators describing the scattering of gluons in anti de Sitter space.



Colloquium: "The First 250 Years of Physics and Astronomy at Penn"

Paul Heiney (University of Pennsylvania Emeritus)
- DRL A4

The histories of physics and astronomy at Penn will be presented primarily through the lives of prominent individuals, culminating in the 1994 merger of the Physics and Astronomy Departments.  We…



High Energy Theory seminar: Self-Similar Quasicrystals and Hyperbolic Honeycombs

Justin Kulp (SCGP)
- DRL 3C6

Most people are familiar with periodic tessellations and lattices; from the sidewalk outside David Rittenhouse Laboratory to their favourite spin systems. In this talk, I will discuss two less familiar…



Astrophysics seminar: New Cosmology Constraints from the Hyper SuprimeCam Year 3 Data Release

Roohi Dalal (Princeton University)
- DRL 4E19

The Hyper Suprime-Cam (HSC) survey is the deepest Stage III weak lensing experiment, going to ~26 mag with exquisite seeing. The depth and image quality achieved by HSC allow us to probe cosmology using…



Condensed Matter Seminar: Controlling the assembly of molecular and colloidal liquid crystals

Lisa Tran (Utrecht University)
- David Rittenhouse Laboratory A4

Liquid crystals are the basis of the modern display industry because of their unique properties. Yet, liquid crystalline ordering occurs in systems beyond displays and across length scales: from…
