Motivated by black hole physics, we study the relationship between quantum chaos, holographic complexity, and fined grained notions of randomness. First, we develop a diagnostic of quantum chaos by directly considering the time evolution of a simple...

Conformal bootstrap equations have demonstrated a strong constraining power in various spacetime dimensions. However, the most exciting results concerning the low-lying spectrum of operators have only been derived using extensive numerics. It is...

When a M5 branes probes the singular locus of the D,E type ALE orbifold, the M5 brane exhibits fractionation, which corresponds to activating tensor branch moduli of the 6d N=(1,0) SCFT living on the M5. I explain how the fractionation patterns can...

The enhanced super-Virasoro symmetries in 2d have allowed us to extract many BPS quantities exactly from 2d superconformal field theories (SCFT). In this talk, we will take advantage of our past knowledge about 2d (2,2) SCFTs, combining with the...

I will describe a proposal for computing the Schur limit of the superconformal index of four-dimensional N = 2 field theories, which counts local operators in the UV, from the spectrum of BPS particles on the Coulomb branch. This proposal can be...

I will describe a new approach to determining the bulk geometry from a dual field theory. This is based on a special class of spacelike cross-sections of the boundary called light-cone cuts. I will first show that the conformal metric in the bulk (i...

Little string theories are UV complete non-local 6D theories decoupled from gravity in which there is an intrinsic string scale. I will present a systematic approach to the construction of supersymmetric little string theories via F-theory. I will...

Moonshine in mathematics originally referred to unexpected connections between the modular J function and the representation theory of the Monster, the largest sporadic finite group. Recently new kinds of moonshine have been discovered connecting...
