The Future of Numerical Relativity: Gravitational Memory, BMS Frames, and More
As was realized by Bondi, Metzner, van der Burg, and Sachs (BMS), the symmetry group of asymptotic infinity is not the Poincaré group, but an infinite-dimensional group called the BMS...

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...

: From black holes to the Big Bang: astrophysics and cosmology with gravitational waves and their electromagnetic counterparts
The growing catalog of gravitational-wave signals from compact object mergers has allowed us to study the properties of black holes and neutron stars more precisely than ever before and has...

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...
