Chern-Simons action and the Carrollian Cotton tensors
Olivera Miskovic, Rodrigo Olea, P. Marios Petropoulos +2
In three-dimensional pseudo-Riemannian manifolds, the Cotton tensor arises as the variation of the gravitational Chern-Simons action with respect to the metric. It is Weyl-covarian…
Flat from anti-de Sitter
Andrea Campoleoni, Arnaud Delfante, Simon Pekar +3
Ricci-flat solutions to Einstein's equations in four dimensions are obtained as the flat limit of Einstein spacetimes with negative cosmological constant. In the limiting process,…
Ehlers, Carroll, Charges and Dual Charges
Nehal Mittal, P. Marios Petropoulos, David Rivera-Betancour +1
We unravel the boundary manifestation of Ehlers' hidden Möbius symmetry present in four-dimensional Ricci-flat spacetimes that enjoy a time-like isometry and are Petrov-algebraic.…
Holographic Lorentz and Carroll Frames
Andrea Campoleoni, Luca Ciambelli, Arnaud Delfante +3
Relaxing the Bondi gauge, the solution space of three-dimensional gravity in the metric formulation has been shown to contain an additional free function that promotes the boundary…
Relativistic Fluids, Hydrodynamic Frames and their Galilean versus Carrollian Avatars
Anastasios C. Petkou, P. Marios Petropoulos, David Rivera Betancour +1
We comprehensively study Galilean and Carrollian hydrodynamics on arbitrary backgrounds, in the presence of a matter/charge conserved current. For this purpose, we follow two disti…
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…
