An operator-algebraic formulation of self-testing
We give a new definition of self-testing for correlations in terms of states on C*-algebras. We show that this definition is equivalent to the standard definition for any class of...

Bootstrapping N = 4 sYM correlators using integrability
In this talk we combine integrability and conformal bootstrap to learn about correlation functions of planar maximally supersymmetric Yang- Mills theory. Focusing on correlators of four stress-tensor multiplets, we first...

Notes on Rapid AI Progress
In this talk I'll try to summarize why AI is making such rapid progress and why I expect that it will continue, leading to enormous impacts on pretty much everything...

The Complexity and (Un)Computability of Quantum Phase Transitions
The phase diagram of a material is of central importance in describing the properties and behaviour of a condensed matter system. Indeed, the study of quantum phase transitions has formed...

Holographic scattering from quantum error-correction
We revisit the problem of how interactions emerge in quantum gravity. Namely, we show that bulk scattering of multiple particles in the AdS space requires multipartite entanglement on the boundary...

Localizing Information in Quantum Gravity and State-dressed Local Operators in AdS/CFT
It is well known that quantum information can be strictly localized in quantum field theory. Similarly, one can also localize information in classical gravity up to quantities like the ADM...

The holographic dual of Renyi relative entropy
The relative entropy is a measure of the distinguishability of two quantum states. A great deal of progress has been made in the study of the relative entropy between an...

Strings on the Keldysh Contour
There is a fundamental tension between what string theory computes (S-matrix elements) and what you can compute in QFT on a time-dependent backgrounds (real time operator expectation values). The prescription...
