The three-dimensional Galilean black hole
Luis Avilés, Oscar Fuentealba, Diego Hidalgo +1
We report a novel solution of three-dimensional Galilean Anti-de Sitter gravity. The theory can be formulated as a topological gauge theory invariant under the doubly extended Newt…
Logarithmic supertranslations as asymptotic symmetries of gravity at null infinity
Oscar Fuentealba, Marc Henneaux, Sébastien Robert +1
Logarithmic supertranslations have been shown recently to be symmetries of the gravitational field at spatial infinity. We extend this work by proving explicitly that they are also…
Logarithmic angle-dependent gauge transformations at null infinity
Oscar Fuentealba, Marc Henneaux
Logarithmic angle-dependent gauge transformations are symmetries of electromagnetism that are canonically conjugate to the standard angle-dependent transform…
AdS Carroll gravity: asymptotic symmetries and C-thermal configurations
Luis Avilés, Oscar Fuentealba, Diego Hidalgo +1
The asymptotic structure of three-dimensional Carroll gravity with negative cosmological constant is studied. We formulate a consistent set of boundary conditions preserved by an i…
Enhanced Conformal Symmetries
Oscar Fuentealba, Iva Lovrekovic, David Tempo +1
An enhanced version of the conformal BMS algebra is presented. It is shown to emerge from the asymptotic structure of an extension of conformal gravity in 3D by Pope and Town…
Logarithmic matching between past infinity and future infinity: The massless scalar field
Oscar Fuentealba, Marc Henneaux
Matching conditions relating the fields at the future of past null infinity with the fields at the past of future null infinity play a central role in the analysis of asymptotic sy…
Non-minimal couplings to -gauge fields and asymptotic symmetries

Oscar Fuentealba, Ricardo Troncoso
-form electrodynamics in dimensions is shown to emerge as the edge modes of a topological field theory with a precise set of boundary conditions, through the Hamiltoni…

Oscar Fuentealba, Marc Henneaux
We show that the non-linear BMS symmetry algebra of asymptotically flat Einstein gravity in five dimensions, as well as the super-BMS superalgebra of asymptotically flat su…
Asymptotic symmetry algebra of Einstein gravity and Lorentz generators
Oscar Fuentealba, Marc Henneaux, Cédric Troessaert
The asymptotic symmetry algebra of four-dimensional Einstein gravity in the asymptotically flat context has been shown recently to be the direct sum of the Poincaré algebra and of…

The asymptotic symmetries of electromagnetism in all higher spacetime dimensions are extended, by incorporating consistently angle-dependent gauge transformations with…

Oscar Fuentealba, Marc Henneaux, Cédric Troessaert
We extend the asymptotic symmetries of electromagnetism in order to consistently include angle-dependent gauge transformations that involve terms growing at spatial infi…

Marcela Cárdenas, Oscar Fuentealba, Cristián Martínez +1
Einstein gravity minimally coupled to a scalar field with a two-parameter Higgs-like self-interaction in three spacetime dimensions is recast in terms of a Chern-Simons form for th…
Logarithmic supertranslations and supertranslation-invariant Lorentz charges
Oscar Fuentealba, Marc Henneaux, Cédric Troessaert
We extend the BMS(4) group by adding logarithmic supertranslations. This is done by relaxing the boundary conditions on the metric and its conjugate momentum at spatial infinity in…

Local supersymmetry and the square roots of Bondi-Metzner-Sachs supertranslations
Oscar Fuentealba, Marc Henneaux, Sucheta Majumdar +2
Super-BMS algebras -- also called BMS superalgebras -- are graded extensions of the BMS algebra. They can be of two different types: they can contain either a finite nu…
