Radiative Asymptotic Symmetries of 3D Einstein-Maxwell Theory
Jorrit Bosma, Marc Geiller, Sucheta Majumdar +1
We study the null asymptotic structure of Einstein-Maxwell theory in three-dimensional (3D) spacetimes. Although devoid of bulk gravitational degrees of freedom, the system admits…
Towards a quadratic Poisson algebra for the subtracted classical monodromy of Symmetric Space Sine-Gordon theories
Francois Delduc, Ben Hoare, Marc Magro
Symmetric Space Sine-Gordon theories are two-dimensional massive integrable field theories, generalising the Sine-Gordon and Complex Sine-Gordon theories. To study their integrabil…
BMS symmetry in gravity: Front form versus Instant form
Sudarshan Ananth, Sucheta Majumdar
In General Relativity, the allowed set of diffeomorphisms or gauge transformations at asymptotic infinity forms the BMS group, an infinite-dimensional extension of the Poincaré gro…
Corner symmetry and quantum geometry
Laurent Freidel, Marc Geiller, Wolfgang Wieland
By virtue of the Noether theorems, the vast gauge redundancy of general relativity provides us with a rich algebra of boundary charges that generate physical symmetries. These char…
