IAS High Energy Theory Seminar

I will discuss the potential importance of a dark-sector phase transition in the early universe in setting the measured relic abundance, for a simple scenario with strongly interacting dark matter. Enhancement of the dark matter density within...

Fracton phases of matter exhibit striking behaviour which seemingly renders them beyond the standard topological quantum field theory (TQFT) paradigm for gapped quantum phases. In this talk, I will discuss progress towards understanding fracton...

In the first half of the talk, I will review the notion of non-invertible symmetries and how they help us to analyze certain strongly coupled QFTs like 2d Adjoint QCD. Then, I discuss the representation theory of non-invertible symmetries and use it...

I will discuss some applications of brane constructions of rational integrable spin chains with Verma modules. These spin chains appear in various gauge theories. They can be created in 4d Chern-Simons theories with line operators, mapped to massive...

We study collisions of localized shockwaves behind the horizon of the eternal AdS black hole. We give a holographic boundary description in terms of the overlap of two growing perturbations in a shared quantum circuit. Due to a competition between...

We study Chern-Simons theories at large N with either bosonic or fermionic matter in the fundamental representation. The most fundamental operators in these theories are mesonic line operators, the simplest example being Wilson lines ending on...

We discuss emergent type III1 von Neumann algebraic structures in the large N limit of certain class of quantum field theories. We show that this is important for understanding various aspects of bulk physics in the AdS/CFT duality, including...

Recent B-meson data show a reinforced set of deviations from the Standard Model predictions, pointing to violations of lepton flavor universality. I will critically review these data and discuss their theoretical interpretation, including their...

 In this talk, we will discuss quantum corrections in the gravitational path integral around nearly 1/16-BPS black holes in asymptotically AdS5 x S5 space, dual to heavy operators in N=4 SYM. We argue these quantum corrections come from a version of...
