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…
