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…
