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…
Soft gluon theorems in curved spacetime
Peng Cheng, Pujian Mao
In this paper, we derive a soft gluon theorem in the near horizon region of the Schwarzschild black hole from the Ward identity of the near horizon large gauge transformation. The…
deformed soft theorem
Song He, Pujian Mao, Xin-Cheng Mao
In this paper, we derive a deformed soft graviton theorem in the context of celestial holography. As a concrete example, it illustrates that a two-dimensional irrelevant…
Notes on Wormhole Cancellation and Factorization
Peng Cheng, Pujian Mao
In AdS/CFT, partition functions of decoupled CFTs living on separate asymptotic boundaries factorize. However, the presence of bulk wormholes connecting different boundaries tends…
Soft theorems in curved spacetime
Peng Cheng, Pujian Mao
In this paper, we derive a soft photon theorem in the near horizon region of the Schwarzschild black hole from the Ward identity of the near horizon large gauge transformation. The…
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…
Symmetries at Causal Boundaries in 2D and 3D Gravity
H. Adami, Pujian Mao, M. M. Sheikh-Jabbari +2
We study 2d and 3d gravity theories on spacetimes with causal (timelike or null) codimension one boundaries while allowing for variations in the position of the boundary. We constr…
Near horizon gravitational charges
Hai-Shan Liu, Pujian Mao
In this paper, we study the near horizon symmetry and gravitational charges in the Newman-Penrose formalism. In particular we investigate the effect from topological terms. We find…
