Conformal Renormalisation of 8D Einstein Gravity
Giorgos Anastasiou, Ignacio J. Araya, Nicolas Boulanger +2
We show that Holographic Renormalisation (HR) in eight dimensions is encoded in the unique conformal gravity theory that admits an Einstein sector with constant negative curvature.…
Holographic Weyl Anomaly and Kounterterms in AdS gravity
Giorgos Anastasiou, Jahaira Bonifacio-Chavez, Olivera Miskovic +1
The addition of Kounterterms to Einstein gravity leads to a finite action for asymptotically anti-de Sitter (AdS) spaces with a conformally flat boundary. In that sense, it provide…
Universality of pseudoentropy for deformed spheres in dS/CFT
Giorgos Anastasiou, Ignacio J. Araya, Avijit Das +1
We determine the universal part of pseudoentropy for small shape deformations of spherical entangling surfaces in the context of de Sitter/conformal field theory (dS/CFT) correspon…
Renormalized pseudoentropy in dS/CFT
Giorgos Anastasiou, Ignacio J. Araya, Avijit Das +1
We study holographic pseudoentropy for subregions in non-unitary Euclidean conformal field theories (CFTs) within the framework of the de Sitter/conformal field theory (dS/CFT) cor…
Renormalization of Einstein-Gauss-Bonnet AdS gravity
Giorgos Anastasiou, Ignacio J. Araya, Avik Chakraborty +2
The asymptotic analysis for the metric of a generic solution of Einstein-Gauss-Bonnet AdS theory is provided by solving the field equations in the Fefferman-Graham frame. Using sta…
Asymptotic analysis of energy functionals in anti-de Sitter spacetimes
Giorgos Anastasiou, Martin Bravo, Rodrigo Olea
Conformal Gravity (CG) is a Weyl--invariant metric theory whose action is free from divergences for generic asymptotically anti-de Sitter spaces. For Neumann boundary conditions, i…
