DOI: 10.1007/jhep10(2021)211

Abstract: Abstract We study the classical double copy for ungauged half-maximal supergravities using the Kaluza-Klein reduction of double field theory (DFT). We construct a general formula for the Kaluza-Klein (KK) reduction of the DFT Kerr-Schild ansatz.… read more here.

DOI: 10.1103/physrevd.102.086015

Abstract: We apply the classical double copy procedure to a class of regular, non-singular black hole solutions. We give several examples, paying particular attention to a string-theory-corrected black hole solution emerging from T-duality. Non-perturbative stringy corrections… read more here.

DOI: 10.1103/physrevd.104.105012

Abstract: We extend the Kerr-Schild double copy to the case of a probe particle moving in the Kerr-Schild background. In particular, we solve Wong’s equations for a test color charge in a Coulomb nonAbelian potential (… read more here.

DOI: 10.1103/physrevd.95.125010

Abstract: We construct perturbative classical solutions of the Yang-Mills equations coupled to dynamical point particles carrying color charge. By applying a set of color to kinematics replacement rules first introduced by Bern, Carrasco and Johansson, these… read more here.

DOI: 10.1103/physrevlett.130.071603

Abstract: Kerr-Schild double copy is shown to extend naturally to all free symmetric gauge fields propagating on (A)dS in any dimension. Similarly to the standard lower-spin case, the higher-spin multicopy comes along with the zeroth, single,… read more here.

recommendations! Published in 2025 at "Physical review letters"

DOI: 10.1103/xn1j-ddcc

Abstract: The double copy relates gauge and gravitational theories, with widespread application to quantum scattering amplitudes and classical perturbative results. It also connects exact classical solutions of Abelian gauge and gravitational theories in a small number… read more here.
