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.…
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…
Bulkcone Singularities and Complex Geodesics
Ignacio J. Araya, Chantelle Esper, Yueke Jia +2
Thermal correlators in holographic CFTs on a sphere exhibit bulk-cone singularities at points connected by null geodesics in the bulk. The operator product expansion analysis of th…
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…
Higher-dimensional Willmore energy as holographic entanglement entropy
Giorgos Anastasiou, Ignacio J. Araya, Pablo Bueno +3
The vacuum entanglement entropy of a general conformal field theory (CFT) in spacetime dimensions contains a universal term, , which has a complicated and non-local dep…
