“Quantum Amplitudes and Classical Gravity”

ABSTRACT:

Scattering amplitudes in quantum field theory have received a lot of attention in recent years. We have learned that amplitudes provide a surprising link, known as the double copy, between Einstein gravity and Yang-Mills theory. I will explain why the double copy persists at the classical level, and discuss the resulting two-way flow of knowledge between amplitudes and gravity.
