Classical double copy at null infinity

  title={Classical double copy at null infinity},
  author={Tim Adamo and Uri Kol},
We give two double copy prescriptions which construct asymptotically flat solutions in gravity from asymptotically flat gauge fields. The first prescription applies to radiative fields, which are non-linear vacuum solutions determined by characteristic data at null infinity. For any two such radiative gauge fields (linear or non-linear), the characteristic data of a radiative metric, dilaton and axion is constructed by a simple ‘squaring’ procedure, giving a classical double copy at the level… Expand
