Modified Double Copy for Quasitopological Gravity with Matter

Abstract

We extend the modified double-copy construction to quasitopological gravity (QTG) coupled to matter. Spherically symmetric QTG solutions in D dimensions are generated from an auxiliary gauge field in a flat (D+1)-dimensional spacetime. The gravitational field equations reduce to two relations determined by the QTG generating function and the matter stress--energy tensor. For a broad class of spherically symmetric matter sources, solutions of the auxiliary gauge-field equations can be used to construct exact solutions of the QTG field equations. The framework applies to Maxwell theory, nonlinear electrodynamics, and Yang--Mills theory, encompasses both static and Vaidya-type solutions, and reproduces the Einstein-gravity limit.
