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, Marc Henneaux, Jules Mas
We analyse the asymptotic symmetries of electromagnetism non-minimally coupled to scalar fields, with non-minimal couplings of the Fermi type that occur in extended supergravity mo…
