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…
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…
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…
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…
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…
Weyl Charges in Asymptotically Locally AdS Spacetimes
Francesco Alessio, Glenn Barnich, Luca Ciambelli +2
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…
Asymptotic structure of Einstein-Gauss-Bonnet theory in lower dimensions
H. Lu, Pujian Mao
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…
Asymptotic Structure of Einstein-Maxwell-Dilaton Theory and Its Five Dimensional Origin
H. Lü, Pujian Mao, Jun-Bao Wu
We consider Einstein-Maxwell-dilaton theory in four dimensions including the Kaluza-Klein theory and obtain the general asymptotic solutions in Bondi gauge. We find that there are…
Note on soft theorems and memories in even dimensions
Pujian Mao, Hao Ouyang
Recently, it has been shown that the Weinberg's formula for soft graviton production is essentially a Fourier transformation of the formula for gravitational memory which provides…
Note on asymptotic symmetries and soft gluon theorems
Pujian Mao, Jun-Bao Wu
Recently, the leading soft gluon theorem with single soft emission was shown to be the Ward identity of a two dimensional -Kac-Moody symmetry. In this note, we show that th…
New electromagnetic memories and soft photon theorems
Pujian Mao, Hao Ouyang, Jun-Bao Wu +1
In this paper, we present a new type of electromagnetic memory. It is a `magnetic' type, or B mode, radiation memory effect. Rather than a residual velocity, we find a position dis…
BMS Supertranslations and Not So Soft Gravitons
Eduardo Conde, Pujian Mao
In a previous article, we have argued that Low's sub-leading soft photon theorem can be recovered as a Ward identity associated to the same large gauge transformations that control…
Soft hairs on isolated horizon implanted by electromagnetic fields
Pujian Mao, Xiaoning Wu, Hongbao Zhang
Inspired by the recent proposal of soft hair on black holes in Phys. Rev. Lett. 116, 231301 (2016), we have shown that an isolated horizon carries soft hairs implanted by electroma…
Remarks on Asymptotic Symmetries and the Sub-leading Soft Photon Theorem
Eduardo Conde, Pujian Mao
A deep connection has been recently established between soft theorems and symmetries at null infinity in gravity and gauge theories, recasting the former as Ward identities of the…
Symplectic and Killing Symmetries of AdS Gravity: Holographic vs Boundary Gravitons
G. Compère, P. Mao, A. Seraj +1
The set of solutions to the AdS Einstein gravity with Brown-Henneaux boundary conditions is known to be a family of metrics labeled by two arbitrary periodic functions, respect…
Acceleration of particles in Einstein-Maxwell-dilaton black holes
Pu-Jian Mao, Ran Li, Lin-Yu Jia +1
It has recently been pointed out that, under certain conditions, the energy of particles accelerated by black holes in the center-of-mass frame can become arbitrarily high. In this…
