The Cosmological Grassmannian

Guilherme Leite Pimentel
(Pisa SNS)
Abstract
I will show how a Grassmannian turns out to be the natural kinematic space for describing correlation functions of massless spinning particles, in four dimensional (Anti)-de Sitter space.
In this kinematic space, tree-level cosmological correlators factorize in a simple way and can be bootstrapped with rather ease, revealing some hidden beauty.

Anomalies of Defect Parameter Spaces and a Spin-Flux Duality

Brandon Rayhaun
(IAS)
Abstract

I will explain how the irreversibility of the renormalization group together with anomalies, including anomalies in the space of coupling constants, can be used to constrain the IR phases of defects in familiar quantum field theories. As an example, I will use these techniques to provide evidence for a conjectural "spin-flux duality" which describes how certain line operators are mapped across particle/vortex duality in 2+1d.

From Theorems to Serums, From Cryptography to Cosmology … and The Simpsons - Simon Singh

Further Information

Join science writer Simon Singh on a whistle-stop tour through two decades of his bestselling books. 'Fermat’s Last Theorem' looks at one of the biggest mathematical puzzles of the millennium; 'The Code Book' shares the secrets of cryptology; 'Big Bang' explores the history of cosmology; 'Trick or Treatment' asks some hard questions about alternative medicine; and 'The Simpsons and Their Mathematical Secrets' explains how TV writers, throughout the show’s 35-year history, have smuggled in mathematical jokes.
