Special Year Learning Seminar

The geometry of polynomial functors
10:30am|Simonyi 101 and Remote Access

In these two talks, I will discuss the structure of certain varieties that depend functorially on the choice of a finite-dimensional vector space. Examples include the variety of d-way tensors of "slice rank" at most k and the variety of degree-d...

Institute for Advanced Study Astrophysics Seminar

Fireball in Fast Radio Bursts
Kunihito Ioka
11:00am|Bloomberg Lecture Hall

Fast radio bursts (FRBs) are the brightest radio transients in the universe. Since the unexpected discovery in the 21st century, their extreme nature is one of the biggest mysteries of astrophysics. FRBs are also unique probes of the universe...

Tilted Planets: Exciting Exoplanetary Obliquities via Spin-Orbit Resonances
Yubo Su
12:15pm|Hybrid Zoom and Grad Central Peyton

The obliquity of a planet, the tilt between its spin and orbital axes, reflects the evolutionary history of the planet. In our own Solar System, the 98 degree obliquity of Uranus is hypothesized to be the result of giant impacts during its formation...

Princeton University Gravity Initiative Special Seminar

Black Holes Are Watching You
Gautam Satishchandran
12:30pm|Princeton University, Jadwin Hall, Princeton Gravity Initiative, 4th Floor & Zoom

Abstract: We show that if a massive body is put in a quantum superposition of spatially separated states, the mere presence of a black hole in the vicinity of the body will eventually destroy the coherence of the superposition. This occurs because...

Rutgers University Astrophysics Seminar

Andromeda as a Stepping Stone to the Local Volume: Resolved Stellar Chemodynamics of Extragalactic Streams, Shells, and Disks
Ivanna Escala
2:00pm|Serin Hall, Room W330

Modern spectroscopic studies of resolved stellar populations in Andromeda (M31) will connect the Milky Way (MW) to future observations of disk galaxies in the Local Volume. Thus, our understanding of M31's merger history will be a foundation upon...

Multimessenger Plasma Physics Center (MPPC) Seminar

High-Energy Neutrino Astrophysics in the Multimessenger Era
3:00pm|Virtual

The discovery of high-energy cosmic neutrinos opened a new window of astroparticle physics. Their origin is a new mystery in the field, which is tightly connected to the long-standing puzzle about the origin of cosmic rays. I will discuss...

Princeton University Department of Physics Donald R. Hamilton Colloquium Series

Superconductivity in Infinite-Layer Nickelates
Harold Hwang
4:00pm|Jadwin Hall A-10

Abstract: 

Finding unconventional superconductors in proximity to various strongly correlated electronic phases has been a recurring theme in materials as diverse as heavy fermion compounds, cuprates, pnictides, and twisted bilayer graphene. The...

Joint IAS/PU Number Theory Seminar

New Cohen-Lenstra heuristics by constructing measures from moments
Will Sawin
4:30pm|Simonyi Hall 101 and Remote Access

The Cohen-Lenstra heuristics give predictions for the distribution of the class groups of a random quadratic number field. Cohen and Martinet generalized them to predict the distribution of the class groups of random extensions of a fixed base field...

Probability Seminar

Transcience for the interchange process in dimension 5
Allan Sly
11:15am|Simonyi 101 and Remote Access

The interchange process \sigma_T is a random permutation valued process on a graph evolving in time by transpositions on its edges at rate 1. On Z^d, when T is small all the cycles of the permutation \sigma_T are finite almost surely. In dimension d...
