Regge Dilaton Gravity from BF Theory
Florian Girelli, Christopher Pollack
In this work we investigate the relation between gauge and geometric descriptions of two-dimensional dilaton gravity at the level of discrete path integrals. We develop a Regge dis…
A Covariant Formulation of Logarithmic Supertranslations at Spatial Infinity
Florian Girelli, Simon Langenscheidt, Giulio Neri +2
We investigate the asymptotic symmetries of asymptotically flat spacetimes at spatial infinity. We propose a new symplectic structure and conservative boundary conditions in a poly…
Beyond Noether: A Covariant Study of Poisson-Lie Symmetries in Low Dimensional Field Theory
Florian Girelli, Christopher Pollack, Aldo Riello
We explore global Poisson-Lie (PL) symmetries using a Lagrangian, or "covariant phase space" approach, that manifestly preserves spacetime covariance. PL symmetries are the classic…
Experimentally bounding deviations from quantum theory for a photonic three-level system using theory-agnostic tomography
Michael Grabowecky, Christopher Pollack, Andrew Cameron +2
If one seeks to test quantum theory against many alternatives in a landscape of possible physical theories, then it is crucial to be able to analyze experimental data in a theory-a…
Lower-dimensional Gauss-Bonnet Gravity and BTZ Black Holes
Robie A. Hennigar, David Kubiznak, Robert B. Mann +1
We consider the limit of Gauss-Bonnet gravity. We find two distinct but similar versions of the theory and obtain black hole solutions for each. For one theory the solutio…
On Taking the limit of Gauss-Bonnet Gravity: Theory and Solutions
Robie A. Hennigar, David Kubiznak, Robert B. Mann +1
We comment on the recently introduced Gauss-Bonnet gravity in four dimensions. We argue that it does not make sense to consider this theory to be defined by a set of solut…
