Character of the highest weight module of BMS algebra realized on codimensional-two boundary
Bin Chen, Song He, Pujian Mao +1
In this paper, we investigate the highest weight representation (HWR) of the three and four-dimensional Bondi-Metzner-Sachs (BMS) algebra realized on the codimension-two boundary o…
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…
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…
