Weyl double copy in type D spacetime in four and five dimensions
Weicheng Zhao, Pu-Jian Mao, Jun-Bao Wu
In this paper, we present a second realization of the Weyl double copy (WDC) in four-dimensional algebraic type D spacetime. We show that any type D vacuum solution admits an algeb…
Five dimensional Weyl double copy
Weicheng Zhao, Pu-Jian Mao, Jun-Bao Wu
The Weyl double copy (WDC) relation connects the Weyl tensor of the gravity theory and the field strength tensor of the Maxwell theory, which provides a concrete realization of the…
Gravitational vacua in the Newman-Penrose formalism
Pujian Mao
In this paper, we derive the generic solution of the Newman-Penrose equations in the Newman-Unti gauge with vanishing curvature tensor. The obtained solutions are the vacua of the…
Twisting asymptotic symmetries and algebraically special vacuum solutions
Pujian Mao, Weicheng Zhao
In this paper, we study asymptotic symmetries and algebraically special exact solutions in the Newman-Penrose formalism. Removing the hypersurface orthogonal condition in the well…
