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…
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…
