IAS Amplitudes Group Meeting

Rays, Residues and the Moduli Space of Polygons
2:30pm|Bloomberg Lecture Hall (IAS)

Abstract: We describe a (surprisingly) novel, uniform formula for all inverse propagators appearing in $tr(\phi^3)$ amplitudes which are dual to a basis of rays of the tropical Grassmannian $TropG(2,n)$.  Our formula manifests the standard kinematic...

Duality of Turbulence to a Solvable String Theory with Discrete Target Space
11:00am|Bloomberg Lecture Hall (IAS)

Abstract: The Navier–Stokes (NS) equations describe fluid dynamics through a high-dimensional, nonlinear partial differential equations (PDEs) system. Despite their fundamental importance, their behavior in turbulent regimes remains incompletely...

Physical Applications of Fusion 2-Categories
Matthew Yu
11:00am|Bloomberg Lecture Hall (IAS)

Abstract: Fusion 2-categories offer a higher dimensional generalization of the category of symmetries in (1+1)d. I will explain how to leverage fusion 2-categories in a special case and apply them to understand the categorical structure of (3+1)d...
