I will review some of the connections between asymptotic symmetry groups, soft theorems for scattering amplitudes, and memory effects. If time permits I will also discuss special boundary operators for asymptotically flat gravity and their relation...

All of the tree amplitudes are constructed for four supersymmetric theories in six dimensions using spinor-helicity variables and the CHY formalism. Two of the theories, the world volume theories of an M5-brane and a D5-brane, only have nonzero...

We prove that higher-dimension operators contribute positively to the entropy of a thermodynamically stable black hole at fixed mass and charge. Our results apply whenever the dominant corrections originate at tree level from quantum field theoretic...

Entanglement is an important property of quantum systems, but its precise definition in field theory poses some challenges. The problem is particularly acute in gauge theories and string theory, where extended objects such as Wilson loops and...

I will sample a few interesting results in the subject of $T\bar T$ deformation, mostly from a field-theoretic point of view. I will start with spectrum of the $T\bar T$ deformed QFT and comment on its stringy nature. Then I will talk about the...

Here are some references for Haah's code and the larger world of "fractons". This list is far from complete and does not accurately capture the history of the subject.
