Soft theorems in de Sitter spacetime
Pujian Mao, Kai-Yu Zhang
In this paper, we derive a soft photon theorem and a soft gluon theorem in the de Sitter spacetime from the Ward identity of the near cosmological horizon large gauge transformatio…
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…
Loop corrections versus marginal deformation in celestial holography
Song He, Pujian Mao, Xin-Cheng Mao
Four-dimensional all-loop amplitudes in QED and gravity exhibit universal Infrared (IR) singularities with a factorization structure. This structure is governed by tree amplitudes…
Anisotropic scaling non-relativistic holography: a symmetry perspective
H. Lü, Pujian Mao, Jun-Bao Wu
We study the holographic dual of the two dimensional non-relativistic conformal field theory with anisotropic scaling from a symmetry perspective. We construct a new four dimension…
Angular momentum and memory effect
Pujian Mao, Jun-Bao Wu, Xiaoning Wu
It is a long-standing problem in general relativity that the notion of angular momentum of an isolated system has supertranslation ambiguity. In this paper, we argue that the ambig…
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…

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…
Hawking radiation of Dirac particles from soft-hairy black holes
Wen-Jie Zhang, Pu-Jian Mao, Jun-Bao Wu
In this paper, we study the Hawking radiation of Dirac particles via tunneling formalism from linearly supertranslated Schwarzschild black hole. We find that the radiation spectrum…
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…
Infrared photons and asymptotic symmetries
Zhengwen Liu, Pujian Mao
S-matrix elements exhibit universal factorization when multiple infrared photons are emitted in scattering processes. We explicitly show that the leading soft factorization of tree…

We discuss an enhancement of the Brown-Henneaux boundary conditions in three-dimensional AdS General Relativity to encompass Weyl transformations of the boundary metric. The result…
Remarks on infinite towers of gravitational memories

An infinite tower of gravitational memories was proposed in \cite{Compere:2019odm} by considering the matter-induced vacuum transition in the impulsive limit. We give an alternativ…

Glenn Barnich, Pujian Mao, Romain Ruzziconi
We derive the expressions for the local, on-shell closed co-dimension 2 forms in the Palatini formulation of general relativity and explicitly show their on-shell equivalence to th…
Asymptotic structure of Einstein-Gauss-Bonnet theory in lower dimensions

Recently, an action principle for the limit of the Einstein-Gauss-Bonnet gravity has been proposed. It is a special scalar-tensor theory that belongs to the family…
Gravitational and electromagnetic memory
Pujian Mao, Wen-Di Tan
We present a unified investigation of memory effect in Einstein-Maxwell theory. We specify two types of memory effect, a velocity kick and a position displacement, by examining the…
