In contrast to symmetry breaking phases of matter,
unconventional phases like spin liquids feature long-range quantum
entanglement and relate to the deconfined phases of gauge theories.
However, the realization of these states in materials
has...
As has been known since the 90s, there is an integrable
structure underlying two-dimensional gravity theories. Recently,
two-dimensional gravity theories have regained an enormous amount
of attention, but now in relation with quantum chaos -...
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...
