Dynamics of Carrollian Scalar Fields
Luca Ciambelli
Adopting an intrinsic Carrollian viewpoint, we show that the generic Carrollian scalar field action is a combination of electric and magnetic actions, found in the literature by ta…
Carroll geodesics
Luca Ciambelli, Daniel Grumiller
Using effective field theory methods, we derive the Carrollian analog of the geodesic action. We find that it contains both `electric' and `magnetic' contributions that are in gene…
Fluid-gravity correspondence and causal first-order relativistic viscous hydrodynamics
Luca Ciambelli, Luis Lehner
The fluid-gravity correspondence is a duality between anti-de Sitter Einstein gravity and a relativistic fluid living at the conformal boundary. We show that one can accommodate th…
Null Raychaudhuri: Canonical Structure and the Dressing Time
Luca Ciambelli, Laurent Freidel, Robert G. Leigh
We initiate a study of gravity focusing on generic null hypersurfaces, non-perturbatively in the Newton coupling. We present an off-shell account of the extended phase space of the…
Symmetries and Charges in Weyl-Fefferman-Graham Gauge
Luca Ciambelli, Arnaud Delfante, Romain Ruzziconi +1
We investigate the asymptotic symmetries of three-dimensional AdS Einstein gravity in the Weyl-Fefferman-Graham gauge, which is a generalization of the Fefferman-Graham gauge induc…
Cornering Quantum Gravity
Luca Ciambelli, Alessandra D'Alise, Vittorio D'Esposito +3
After introducing the covariant phase space calculus, Noether's theorems are discussed, with particular emphasis on Noether's second theorem and the role of gauge symmetries. This…
