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…

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…

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…
