Abstract: The Weyl double copy is a procedure for relating exact solutions in biadjoint scalar, gauge and gravity theories, and relates fields in spacetime directly. Where this procedure comes from, and how general it is, have… read more here.

Abstract: Two modern programs involving analogies between general relativity and electro-magnetism, gravito-electromagnetism (GEM) and the classical double copy (CDC), induce electromagnetic potentials from specific classes of spacetime metrics. We demonstrate such electromagnetic potentials are typically gauge… read more here.

Abstract: Recently the Kerr-Schild double copy of gravitational and gauge fields has been studied at the level of equations of motion: the so called classical double copy. In previous work the self-dual double copy has been… read more here.

DOI: 10.1088/1361-6382/ad8f8c
Abstract: We embed the Penrose limit into the Weyl classical double copy. Thereby, we provide a lift of the double copy properties of plane wave spacetimes into black hole geometries and we open a novel avenue… read more here.
