Plebański-Demiański solutions in bigravity and Kerr-Schild double copy relations using an effective metric
Hugo García-Compeán, César I. Ramos
In this work a formalism for proportional generalized double Kerr-Schild ansatz in bigravity is considered, where both metrics are coupled to matter. We study time-dependent and st…

Hyper-Hermitian Weyl Double Copy
E. Chacón, H. García-Compeán, G. Robles
The self-dual double copy is further explored. In previous work, it has been shown that hyper-Hermitian manifolds also have associated the self-dual gauge theories via Kerr-Schild…
