"D=5 Holomorphic Chern-Simons and the Pure Spinor Superstring"

Superstring amplitudes can be computed using either the N=1 worldsheet supersymmetric prescription of the RNS formalism or the twisted N=2 worldsheet supersymmetric prescription of the pure spinor formalism. Although all amplitudes computed using the two prescriptions coincide, there...

"Magnetic scattering: pairwise little group and pairwise helicity"

I explain the concept of the pairwise little group which leads to the existence of pairwise helicity for multi-particle states. This pairwise helicity is needed to describe the scattering of magnetically charged particles. I show how to implement pairwise helicity into the...

"Anomalies and Symmetry Fractionalization”

’t Hooft anomalies play a central role in informing nonperturbative dynamics.
I will describe how the ’t Hooft anomalies of a physical
system can depend on additional data, whose physical interpretation we elucidate,
and discuss the implications of this for ’t Hooft anomaly matching.

"Topological symmetry in field theory"

Recently there has been lots of activity surrounding generalized notions of symmetry in quantum field theory, including "categorical symmetries", "higher symmetries", "noninvertible symmetries", etc. Inspired by definitions of abstract (finite) groups and algebras and their linear actions, we introduce a...

"Deriving the Simplest Gauge-String Duality"

The simplest large N gauge theory is, arguably, the Gaussian matrix (or more generally, one hermitian matrix) integral. We will explicitly show that arbitrary correlators of single trace operators in this theory (without any double scaling limit) are identical to corresponding physical correlators in a dual...

"Unraveling Turbulence: Modern Viewpoints On An Unsolved Problem"

Fluid turbulence is a major unsolved problem of physics exhibiting an emergent complex structure from simple rules.
We will briefly review the problem and discuss three avenues
towards its solution: field theory, holography and machine learning.

"From geometry to 4D physics"

New insight into the topological structure of Calabi-Yau fourfolds provides a useful tool for organizing our understanding of chiral matter and how the Standard Model of particle physics can arise in the geometrical framework of F-theory. This work ties into a number of themes that have played an important role in Hirosi...
