Title: The double copy from Coulomb to Kerr
Abstract: The double copy relates scattering amplitudes in gauge theory and gravity. Recent work has shown that interaction potentials, spacetime metrics and gravitational waveforms can be extracted from amplitudes - and so the double copy leads to a relationship between classical solutions of gauge theory and gravity. In this talk I will describe these developments, provide a perspective on the Schwarzschild metric as a “square” of the Coulomb charge, and take a look at the “square root” of the Kerr metric.
