Abstract

I will give an overview of the recent progress in the computation and understanding of new structures of scattering amplitudes and related quantities in Quantum Field Theory, gravity and string theory, including all-loop geometries underlying amplitudes and correlators in maximally supersymmetric Yang-Mills theory, as well as the discovery of a combinatorial formulation for real-world scattering of colored scalars, pions and gluons.

Biography

Song He is mostly interested in fundamental questions in QFT, gravity and string theory, as well as applications to particle physics, cosmology and related topics in mathematics. He got his PhD from Peking University in 2009, and worked at Albert-Einstein Institute, Perimeter Institute and Institute for Advanced Study, before joining Institute of Theoretical Physics, Chinese Academy of Sciences in 2015. He was selected for the New Cornerstone Investigator Program in 2025.

Some highlights of his research include a new formulation for scattering of massless particles, discovery of combinatorial geometries underlying real-world scattering (with Arkani-Hamed et al), as well as higher-order/exact results in QFT and quantum gravity.
