Remarks on asymptotic symmetries and the subleading soft photon theorem

- Eduardo Conde, P. Mao
- Physics
- 31 May 2016

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 latter. In… Expand

Symplectic and Killing symmetries of AdS3 gravity: holographic vs boundary gravitons

- G. Compère, P. Mao, A. Seraj, M. M. Sheikh-Jabbari
- Physics
- 19 November 2015

A bstractThe set of solutions to the AdS3 Einstein gravity with Brown-Henneaux boundary conditions is known to be a family of metrics labeled by two arbitrary periodic functions, respectively left… Expand

Note on soft theorems and memories in even dimensions

- P. Mao, Hao Ouyang
- Physics
- 22 July 2017

Abstract 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 an… Expand

Conserved currents in the Cartan formulation of general relativity

- G. Barnich, P. Mao, Romain Ruzziconi
- Physics
- 6 November 2016

We derive the expressions for the local, on-shell closed co-dimension 2 forms in the Cartan formulation of general relativity and explicitly show their equivalence to those of the metric formulation.

BMS supertranslations and not so soft gravitons

- Eduardo Conde, P. Mao
- Physics
- 25 December 2016

A bstractIn a previous article [1], 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 the… Expand

Note on asymptotic symmetries and soft gluon theorems

Recently, the leading soft gluon theorem with single soft emission was shown to be the Ward identity of a two-dimensional G-Kac-Moody symmetry. In this paper, we show that the leading soft gluon… Expand

Three-dimensional asymptotically flat Einstein-Maxwell theory

- G. Barnich, P. Lambert, P. Mao
- Physics
- 3 March 2015

Three-dimensional Einstein–Maxwell theory with non-trivial asymptotics at null infinity is solved. The symmetry algebra is a Virasoro–Kac–Moody type algebra that extends the bms3 algebra of the… Expand

More on gravitational memory

A bstractTwo novel results for the gravitational memory effect are presented in this paper. We first extend the formula for the memory effect to solutions with arbitrary two surface boundary… Expand

Hawking radiation of Dirac particles from the Myers–Perry black hole

In this paper, we apply the quantum anomaly cancelation method and the effective action approach as well as the method of Damour–Ruffini–Sannan to derive Hawking radiation of Dirac particles from the… Expand

New electromagnetic memories and soft photon theorems

- P. Mao, Hao Ouyang, J. Wu, X. Wu
- Physics
- 20 March 2017

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 displacement of a… Expand
