IAS CMP/QFT Group Meeting

Generalizations of Kitaev’s Honeycomb Model and 2+1d Dualities from Braided Fusion Categories
Luisa Eck
2:00pm|Bloomberg Hall Physics Library (IAS)

Abstract: Fusion surface models, as introduced by Inamura and Ohmori, extend the concept of anyon chains to 2+1 dimensions, taking fusion 2-categories as their input. In this talk, I will focus on fusion surface models constructed from braided...

Rutgers University Astrophysics Seminar

Astronomy Re-envisioned: Investigating the Physics of Galaxy Evolution with Machine Learning
John Wu
2:00pm|Serin Hall Rm 401W, Rutgers and Zoom

Machine learning (ML) techniques are revolutionizing our ability to study galaxy evolution and large-scale structure. Convolutional neural networks (CNNs) can now reliably predict galaxies' physical properties, including cold gas content and...

Spectral Minimal Partitions: Local vs Global Minimality
Gregory Berkolaiko
2:30pm|Simonyi Hall 101 and Remote Access

In this overview talk we will explore a variational approach to the problem of Spectral Minimal Partitions (SMPs).  The problem is to partition a domain or a manifold into k subdomains so that the first Dirichlet eigenvalue on each subdomain is as...

Special Year Seminar I

Standard Monomials for Positroid Varieties
Daoji Huang
2:00pm|Simonyi 101 and Remote Access

Influential work of Hodge from the 1940s led the way in using Gröbner bases to combinatorially study the Grassmannian. We follow Hodge's approach to investigate certain subvarieties of the Grassmannian, called positroid varieties. Positroid...

Special Year Seminar II

Kahler Packages on Valuations on Convex Sets and Their Applications
Semyon Alesker
10:00am|Simonyi 101 and Remote Access

A valuation is a finitely additive measure on the class of all convex compact subsets of $R^n$. Over the past two decades, a number of structures has been discovered on the space of translation invariant smooth valuations. Recently, these findings...
