IAS Physics Group Meeting

Modular-Invariant Random Matrix Theory and AdS3 Wormholes
Gabriele Di Ubaldo
11:00am|Bloomberg Lecture Hall (IAS)

Abstract: We develop a non-perturbative definition of RMT2: a generalization of random matrix theory that is compatible with the symmetries of two-dimensional conformal field theory. Given any random matrix ensemble, its n-point spectral...

Special Year Seminar I

KP Solitons, Tropical Curves, and Voronoi Cells
2:00pm|Simonyi 101

The Kadomtsev-Petviashvili (KP) Equation has deep connections to algebraic curves, with solutions constructed from Riemann theta functions in the style of Krichever. As a curve undergoes tropical degeneration, its theta function simplifies to a...

Mathematical Conversations

Aperiodic Square Tilings and Lattices in Products of Trees
6:00pm|Simons Hall Dilworth Room

We will consider finite collections of squares tiles, and ask when we can tile the whole plane in an interesting way. This question is related to the algebraic structure of ‘lattices in products of trees’, which are discrete groups acting...

Special Year Seminar II

Measures on Combinatorial Objects
Andrew Snowden
10:00am|Simonyi 101

Suppose given a class of finite combinatorial structures, such as graphs or total orders. Nate Harman and I recently introduced a notion of measure in this context: this is a rule assigning a number to each structure such that some axioms are...

Institute for Advanced Study Astrophysics Seminar

Radiation and Magnetic Pressure Support in Accretion Disks around Supermassive Black Holes and The Physical Origin of Soft X-ray Excess
Yan-Fei Jiang
11:00am|Bloomberg Lecture Hall

The alpha disk model is widely used to describe the accretion disk structures around supermassive black holes, even though it cannot explain many observed properties of AGNs. Various alternative models have been proposed including the ones where...

IAS High Energy Theory Seminar

Symbiosis between Supersymmetry and Compositeness
Raman Sundrum
1:30pm|Bloomberg Lecture Hall (IAS) & Zoom

Abstract: Theories comprehensively addressing the origin and robustness of the observed hierarchical structure of particle physics face significant challenges from the non-appearance of new particles, explicitly in LHC searches or virtually within...

Joint PU/IAS Number Theory

There Are Infinitely Many Elliptic Curves Over the Rationals of Rank 2
David Zywina
3:30pm|Simonyi 101 and Remote Access

For an elliptic curve E defined over Q, the Mordell-Weil group E(Q) is a finitely generated abelian group. We prove that there are infinitely many elliptic curves E over Q for which E(Q) has rank 2. Our elliptic curves will be given by explicit...

Alexia Corradini (University ofCambridge) :The Lagrangian Ceresa Cycle

In algebraic geometry, the Ceresa cycle provided one of the first examples of a nullhomologous cycle which is not algebraically trivial. I will explain how one can obtain a...

Princeton University Galread [Galactic/Extragalactic Reading Group]

TBA
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...
