BMS in higher space-time dimensions and Non-relativistic BMS
Master's thesis. We present a study of the BMS Group is higher space-time dimensions, and the extension of this group to non-relativistic systems.
Asymptotic conformal symmetry at spatial infinity
In this paper, the effects of adding spatial conformal symmetry to the asymptotic symmetry group of an asymptotically conformally flat spacetime are studied. It is shown that, in addition to the BMS…
Generalized BMS charge algebra
It has been argued that the symmetries of gravity at null infinity should include a Diff$(S^2)$ factor associated to diffeomorphisms on the celestial sphere. However, the standard phase space of…
Superconformal Bondi-Metzner-Sachs Algebra in Three Dimensions.
TLDR
An explicit canonical realization of the conformal extension of BMS_{3} is shown to emerge from the asymptotic structure of conformal gravity in three dimensions, endowed with a new set of boundary conditions.
Lectures on the Infrared Structure of Gravity and Gauge Theory
This is a redacted transcript of a course given by the author at Harvard in spring semester 2016. It contains a pedagogical overview of recent developments connecting the subjects of soft theorems,…
Quantum BMS transformations in conformally flat space-times and holography
We define and study asymptotic Killing and conformal Killing vectors in $d$-dimensional Minkowski, (A)dS, $\mathbb{R}\times S^{d-1}$ and ${\rm AdS}_2\times S^{d-2}$. We construct the associated…
Localisation of soft charges, and thermodynamics of softly hairy black holes
Large gauge transformations (LGT) in asymptotically flat space are generated by charges defined at asymptotic infinity. No method for unambiguously localising these charges into the interior of…
Lie theory for asymptotic symmetries in general relativity: The BMS group
We study the Lie group structure of asymptotic symmetry groups in general relativity from the viewpoint of infinite-dimensional geometry. To this end, we review the geometric definition of asymptotic…
Soldering freedom and BMS-like transformations
When two spacetimes are stitched across a null-shell placed at the horizon of a black hole, BMS-supertranslation like soldering freedom arises if one demands the induced metric on the shell should…
Null hypersurface quantization, electromagnetic duality and asympotic symmetries of Maxwell theory
A bstractIn this paper we consider introducing careful regularization at the quantization of Maxwell theory in the asymptotic null infinity. This allows systematic discussions of the commutators in…

Conformal Carroll groups and BMS symmetry
The Bondi–Metzner–Sachs group is shown to be the conformal extension of Levy-Leblond's 'Carroll' group. Further extension to the Newman–Unti group is also discussed in the Carroll framework.
Asymptotic symmetry algebra of conformal gravity
We compute asymptotic symmetry algebras of conformal gravity. Due to more general boundary conditions allowed in conformal gravity in comparison to those in Einstein gravity, we can classify the…
Symmetries of asymptotically flat four-dimensional spacetimes at null infinity revisited.
It is shown that the symmetry algebra of asymptotically flat spacetimes at null infinity in 4 dimensions should be taken as the semidirect sum of supertranslations with infinitesimal local conformal…
BMS charge algebra
A bstractThe surface charges associated with the symmetries of asymptotically flat four dimensional spacetimes at null infinity are constructed. They realize the symmetry algebra in general only up…
Semiclassical Virasoro Symmetry of the Quantum Gravity S-Matrix

Aspects of the BMS/CFT correspondence
After a review of symmetries and classical solutions involved in the AdS3/CFT2 correspondence, we apply a similar analysis to asymptotically flat spacetimes at null infinity in 3 and 4 dimensions. In…
Supertranslations call for superrotations
We review recent results on symmetries of asymptotically flat spacetimes at null infinity. In higher dimensions, the symmetry algebra realizes the Poincar\'e algebra. In three and four dimensions,…
