Exact Toda Black Holes of Rank-2 Lie Groups
H. Lu, Peng-Yu Wu, Ze-Hua Wu +1
We consider Einstein gravity coupled to two Maxwell fields and one dilatonic scalar, and construct spherically-symmetric and static black holes that are charged under both Maxwell…
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…
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…
Asymptotic Weyl double copy in Newman-Penrose formalism
Pujian Mao, Weicheng Zhao
In this paper, we provide a self-contained investigation of the Weyl double copy in the Newman-Penrose formalism. We examine the Weyl double copy constraints for the general asympt…
Notes on no black hole theorem in three dimensional gravity
Pujian Mao, Weicheng Zhao
In this paper, we revisit the no black hole theorem in three dimensional (3D) gravity in the Newman-Penrose formalism in a generalized Newman-Unti gauge. After adapting the well es…
Null boundary gravitational charges from local Lorentz symmetries
Pujian Mao, Weicheng Zhao
In this paper, we revisit the null boundary gravitational charge in the Newman-Penrose formalism with special emphasis on the charges from local Lorentz transformations. We find th…
Notes on self-dual gravity
Pujian Mao, Weicheng Zhao
In this paper, we study self-dual gravity in the Newman-Penrose formalism. We specify the self-dual solution space from the Newman-Unti solutions. We show that the asymptotic symme…
Note on the asymptotic structure of Kerr-Schild form
Pujian Mao, Weicheng Zhao
The Kerr-Schild form provides a natural way of realizing the classical double copy that relates exact solutions in general relativity to exact solutions in gauge theory. In this pa…
