Radiation in Fluid/Gravity and the Flat Limit
Gabriel Arenas-Henriquez, Luca Ciambelli, Felipe Diaz +2
We explore asymptotically locally anti-de Sitter spacetimes exhibiting gravitational radiative behavior, employing null gauges that allow for a well-defined flat limit. The radiati…
Generalized Fefferman-Graham gauge and boundary Weyl structures
Gabriel Arenas-Henriquez, Felipe Diaz, David Rivera-Betancour
In the framework of AdS/CFT correspondence, the Fefferman--Graham (FG) gauge offers a useful way to express asymptotically anti-de Sitter spaces, allowing a clear identification of…
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.…
Revisiting the Carrollian Scalar Field
David Rivera-Betancour, Matthieu Vilatte
We investigate the (conformally coupled) scalar field on a general Carrollian spacetime in arbitrary dimension. The analysis discloses electric and magnetic dynamics. For both, we…
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…
Renormalized holographic entanglement entropy for Quadratic Curvature Gravity
Giorgos Anastasiou, Ignacio J. Araya, Javier Moreno +2
We derive a covariant expression for the renormalized holographic entanglement entropy for Conformal Field Theories (CFTs) dual to Quadratic Curvature Gravity in arbitrary dimensio…
Shape dependence of renormalized holographic entanglement entropy
Giorgos Anastasiou, Javier Moreno, Rodrigo Olea +1
We study the holographic entanglement entropy of deformed entangling regions in three-dimensional CFTs dual to Einstein-AdS gravity, using a renormalization scheme based on the add…
Topological invariants and the definition of energy in quadratic gravity theory
Gaston Giribet, Olivera Miskovic, Rodrigo Olea +1
We provide a simple method to compute the energy in higher curvature gravity in asymptotically AdS spacetimes in even dimensions. It follows from the combined use of topological te…
Energy in Higher-Derivative Gravity via Topological Regularization
Gaston Giribet, Olivera Miskovic, Rodrigo Olea +1
We give a novel definition of gravitational energy for an arbitrary theory of gravity including quadratic-curvature corrections to Einstein equations. We focus on the theory in fou…
Noether-Wald energy in Critical Gravity
Giorgos Anastasiou, Rodrigo Olea, David Rivera-Betancour
Criticality represents a specific point in the parameter space of a higher-derivative gravity theory, where the linearized field equations become degenerate. In 4D Critical Gravity…
