Chetan begins by reviewing the eikonal approximation, and factorization theorems for amplitudes. Amartya then discusses this in context of quantum gravity, causality constraints and regge behaviour. This brings us to Vasiliev gravity the origins of string theory, and Chetan makes interesting...

Santhosh begins this episode with a discussion about transverse field Ising chains and dualities, anyon algebras, and systems with known spectra but unknown states. Amartya then talks about the relation between the emergence proposal in EFTs and the weak gravity conjecture, the graviton forward...

We reunite in person after nearly 2 years. Chetan begins this episode with a discussion about Witten's recent work on the deep connection between gauge-gravity amplitudes and geometry in twistor space, and how this suggests a more fundamental language underlying gauge theories and gravity; with...
