We study the Eigenstate Thermalization Hypothesis (ETH) in chaotic conformal field theories (CFTs) of arbitrary dimensions. Assuming local ETH, we compute the reduced density matrix of a ball-shaped subsystem of finite size in the infinite volume...

Goldstone modes arising from spontaneously broken symmetries can be added to a hydrodynamic description of charge transport to model quantum critical effects in metals from a symmetry point of view. I will discuss the setup and the effects of weak...

I will give an overview of the integrability-based approach to study correlation functions in planar N=4 SYM. The basic strategy is to "divide and conquer": We decompose the correlators of single-trace operators into fundamental objects called...

A complete and universal equivalence between soft theorems inquantum field theories and asymptotic symmetries in flat spacetimes has recently emerged. We review these developments and show that the equivalence also extends to theories with higher...

The traversable wormhole protocol of Gao, Jafferis and Wall gives us a glimpse behind the horizon of certain black holes. I will describe this effect and discuss some limited applications to the black hole information problem. Based on a recent...

We present recent developments in F-theory compactifications and focus on advances in constructions of globally consistent F-theory compactifications with Abelian and discrete gauge symmetries, emphasizing technical advances and insights into higher...

I formulate the conformal crossing equation in a way that manifests the conformal representation theory. In this form the crossing equation can be generalized to any group. Using SU(2) as a toy model I compute solutions to the crossing equation in...

I will present the concept of a “BPS graph” (a special kind of spectral network) and illustrate its usefulness in the study of theories of class S. BPS graphs encode BPS quivers, even for higher rank and in the presence of non-full punctures, and...

I'll describe the cluster partition function (CPF), a computational tool that uses elements from cluster algebra and representation theory to describe the partition function of Chern-Simons theory with gauge group SL(N,C), on knot complements. I'll...
