Institute for Advanced Study Astrophysics Seminar

Weak gravitational lensing and cosmology
Bhuvnesh Jain
11:00am|Bloomberg Lecture Hall

I will motivate current work in weak gravitational lensing with cosmic and astrophysical puzzles. The evolution of dark energy, the growth of structure and feedback from supermassive black holes are some of the debated questions. I will describe how...

Special Year Research Seminar

Typical and Atypical Intersections: Geometry, Dynamics, and Applications
Gregorio Baldi
1:00pm|Simonyi 101

Many geometric spaces carry natural collections of special submanifolds that encode their internal symmetries. Examples include abelian varieties and their sub-abelian varieties, locally symmetric spaces with their totally geodesic subspaces, period...

Joint IAS/PU Number Theory

On Triple Product L-Functions
Miao Gu
3:30pm|Simonyi 101 and Remote Access

The Poisson summation conjecture of Braverman-Kazhdan, L. Lafforgue, Ngo, and Sakellaridis is an ambitious proposal to prove analytic properties of quite general Langlands L-functions using vast generalizations of the Poisson summation formula. In...

Princeton University Galread [Galactic/Extragalactic Reading Group]

TBA
Hollis Akins
11:00am|Zoom and Peyton Hall, Grand Central

Each week, we hold a relatively informal seminar/discussion series with an emphasis on extra-galactic and large-scale structure astrophysics.

During Galread a leader/visitor presents a recent paper to the discussion group. The PDF of the paper is...

Princeton University Astroplasmas Seminar

Role of Nonlinear Landau Damping for Cosmic-Ray Transport
Benedikt Schroer
12:30pm|Dome Room, Peyton Hall or Zoom

Abstract: The self-confinement picture of cosmic-ray transport often hinges on the linear theory of growth and damping of magnetic perturbations. Especially the balance between the growth of the resonant streaming instability and non-linear Landau...

Computer Science/Discrete Mathematics Seminar I

Trickle-down Theorems for High-dimensional Expanders via Lorentzian Polynomials
Jonathan Leake
11:00am|Simonyi Hall 101 and Remote Access

High-dimensional expanders (HDX) are a generalization of expander graphs which have seen various applications in coding theory, PCPs, pseudorandomness, derandomization, approximate sampling, and beyond. One technique for proving a complex is an HDX...

IAS CMP/QFT Group Meeting

Generalized Symmetries of Relative QFTs and Chiral Algebras
Brandon Rayhaun
11:00am|Bloomberg Lecture Hall (IAS)

Abstract: I will sketch a theory of finite, generalized symmetries of 2D QFTs which live at the boundary of a bulk topological theory in one higher dimension, emphasizing various new ingredients which arise in the presence of a nontrivial bulk. This...

IAS Phenomenology Lunch and Meet

Information Discussions on Phenomenology and New Theories beyond the Standard Model
12:30pm|Bloomberg Hall Biology Conference Room (1st Floor, Room 113)

This semester, we will be beginning a *very informal* get-together every Monday of people interested in/working on phenomenology and new theories beyond the standard model.  The idea is to discuss over lunch, perhaps meet up around 12.20, grab lunch...

Princeton University Gravity Initiative Seminar

Cryptographic tests of the python's lunch conjecture
Michelle Xu
12:30pm|Jadwin Hall, Princeton Gravity Initiative, 4th Floor

Abstract: In AdS/CFT, a spacetime geometry is said to contain a python's lunch when there exist choices of boundary regions with associated entanglement wedges that contain locally but not globally minimal surfaces. Previously, such geometries have...
