The self-dual classical double copy, and the Eguchi-Hanson instanton
The self-dual classical double copy, and the Eguchi-Hanson instanton
The double copy is a map from non-abelian gauge theories to gravity, that has been demonstrated both for scattering amplitudes and exact classical solutions. In this study, we reconsider the double copy for exact solutions that are self-dual in either the gauge or gravity theory. In this case, one may …
