Topological Terms and the Misner String Entropy
Luca Ciambelli, Cristóbal Corral, José Figueroa +2
The method of topological renormalization in anti-de Sitter (AdS) gravity consists in adding to the action a topological term which renders it finite, defining at the same time a w…
Weyl Charges in Asymptotically Locally AdS Spacetimes
Francesco Alessio, Glenn Barnich, Luca Ciambelli +2
We discuss an enhancement of the Brown-Henneaux boundary conditions in three-dimensional AdS General Relativity to encompass Weyl transformations of the boundary metric. The result…
New Chiral Gravity
Luca Ciambelli, Stéphane Detournay, Antoine Somerhausen
The phase space of three-dimensional gravity with Compere-Song-Strominger (CSS) boundary conditions is endowed with asymptotic symmetries consisting in the semi-direct product of a…
Fefferman-Graham and Bondi Gauges in the Fluid/Gravity Correspondence
Luca Ciambelli, Charles Marteau, P. Marios Petropoulos +1
In three-dimensional gravity, we discuss the relation between the Fefferman--Graham gauge, the Bondi gauge and the Eddington--Finkelstein type of gauge, often referred to as the de…
Gauges in Three-Dimensional Gravity and Holographic Fluids
Luca Ciambelli, Charles Marteau, P. Marios Petropoulos +1
Solutions to Einstein's vacuum equations in three dimensions are locally maximally symmetric. They are distinguished by their global properties and their investigation often requir…
